Hamed Moghaddam

The document details the configuration of IP SLA with tracking on a Cisco router to manage primary and backup ISP connections. It describes setting up static routes with different administrative distances, using ICMP echo for reachability tracking, and scripting to automate failover between two ISPs. Additionally, it provides step-by-step commands for configuring IP SLA operations and monitoring their status.

IP SLA withTracking Configuration
IP SLA withTracking Configuration Now we will do Lab for Tracking In here we have as follow Above we have a router (R1) that is connected to two ISPs. We want to use ISP1 as the primary and ISP2 as the backup link. All traffic will be sent towards ISP1 but when it’s unreachable we’ll switch over to ISP2. You can achieve this by using two default routes: R1=f0/0 192.168.12.1 /24 connected to ISP1=192.168.12.2 R1=F0/1 192.168.13.1 /24 connected to ISP2= 192.168.13.3 R1#show ip int brief
IP SLA withTracking Configuration Interface IP-Address OK? Method Status Protocol FastEthernet0/0 192.168.12.1 YES manual up up FastEthernet1/0 192.168.13.1 YES manual up up Serial0/1/0 unassigned YES Unset administratively down down
IP SLA withTracking Configuration R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.12.2 R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.13.3 50 As we see in above we are using the floating Static route that is top one has AD=1 for static route and 2nd one the AD=50 , so when I go to R1#show ip route
IP SLA withTracking Configuration I will see the top commands on the routing tables R1#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 192.168.12.2 to network 0.0.0.0 C 192.168.12.0/24 is directly connected, FastEthernet0/0 C 192.168.13.0/24 is directly connected, FastEthernet0/1 S* 0.0.0.0/0 [1/0] via 192.168.12.2 R1#
IP SLA withTracking Configuration Here R1 can ping both ISP and from above we see it prefer top ISP1 R1#ping 192.168.12.2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.12.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms R1# R1#ping 192.168.13.3 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.13.3, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms R1#
IP SLA withTracking Configuration R1#show cdp neighbors Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone, D - Remote, C - CVTA, M - Two-port Mac Relay Device ID Local Intrfce Holdtme Capability Platform Port ID ISP2 Fas 1/0 136 R 7206VXR Fas 1/0 ISP1 Fas 0/0 143 R 7206VXR Fas 0/0
IP SLA withTracking Configuration Now If I go to R1 and shut down the f0/0 (which is connected to ISP1) then since I have the Floating point the R1 #show ip route will be pointed to ISP2 R1#config t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#int f0/0 R1(config-if)#shut
IP SLA withTracking Configuration R1#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 192.168.13.3 to network 0.0.0.0 C 192.168.13.0/24 is directly connected, FastEthernet0/1 S* 0.0.0.0/0 [50/0] via 192.168.13.3 R1#
IP SLA withTracking Configuration As we see in above now R1 goes to internet via ISP2 , which is called the floating point---- But what happen if the link on ISP1 goes than ; then R1 in his table still will have original route to ISP1=192.168.12.2 so in here we will use the concept of Ip SLA with adding the track on the static route of R1
IP SLA withTracking Configuration Lets bring up the int f0/0 on r1; R1#config t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#int f0/0 R1(config-if)#no shut
IP SLA withTracking Configuration R1#show ip int brief Interface IP-Address OK? Method Status Protocol FastEthernet0/0 192.168.12.1 YES manual up up FastEthernet1/0 192.168.13.1 YES manual up up Serial0/1/0 unassigned YES Unset administratively down down
IP SLA withTracking Configuration R1# R1# R1#show ip rou R1#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 192.168.12.2 to network 0.0.0.0 C 192.168.12.0/24 is directly connected, FastEthernet0/0 C 192.168.13.0/24 is directly connected, FastEthernet0/1 S* 0.0.0.0/0 [1/0] via 192.168.12.2 R1#
IP SLA withTracking Configuration Now life is back to normal, that is using ISP1=192.168.12.2 Now we will do tracking with Ip SLA Step 1) I will create an IP SLA instance that pings the IP address of the ISP1 router: R1(config)#ip sla 1 R1(config-ip-sla)#
IP SLA withTracking Configuration R1(config-ip-sla)#? IP SLAs entry configuration commands: dhcp DHCP Operation dns DNS Query Operation ethernet Ethernet Operations exit Exit Operation Configuration frame-relay Frame-relay Operation ftp FTP Operation http HTTP Operation icmp-echo ICMP Echo Operation icmp-jitter ICMP Jitter Operation path-echo Path Discovered ICMP Echo Operation path-jitter Path Discovered ICMP Jitter Operation tcp-connect TCP Connect Operation udp-echo UDP Echo Operation udp-jitter UDP Jitter Operation voip Voice Over IP Operation

IP SLA withTracking Configuration Now we will use the same concept as before that is icmp-echo R1(config-ip-sla)#icmp-echo 192.168.12.2 ( Point to ISP1=192.168.12.2) R1(config-ip-sla-echo)# R1(config-ip-sla-echo)#?

IP SLA withTracking Configuration Here is show run so far R1#show run ip sla 1 icmp-echo 192.168.12.2 frequency 20
IP SLA withTracking Configuration Step 2) Go back to global configuration to schedule now for forever R1# R1#config t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#ip sla R1(config)#ip sla ? <1-2147483647> Entry Number

IP SLA withTracking Configuration Here is show run so far R1#show run ip sla 1 icmp-echo 192.168.12.2 frequency 20 ip sla schedule 1 life forever start-time now
IP SLA withTracking Configuration let’s check with show commands life is good now R1#show ip sla sta R1#show ip sla statistics IPSLAs Latest Operation Statistics IPSLA operation id: 1 Type of operation: icmp-echo Latest RTT: 1 milliseconds Latest operation start time: *05:40:17.723 UTC Thu Dec 15 2016 Latest operation return code: OK Number of successes: 6 Number of failures: 1 Operation time to live: Forever
IP SLA withTracking Configuration R1#show ip sla statistics IPSLAs Latest Operation Statistics IPSLA operation id: 1 Type of operation: icmp-echo Latest RTT: 1 milliseconds Latest operation start time: *05:40:57.723 UTC Thu Dec 15 2016 Latest operation return code: OK Number of successes: 8 Number of failures: 1 Operation time to live: Forever
IP SLA withTracking Configuration R1#show ip sla statistics IPSLAs Latest Operation Statistics IPSLA operation id: 1 Type of operation: icmp-echo Latest RTT: 1 milliseconds Latest operation start time: *05:41:37.723 UTC Thu Dec 15 2016 Latest operation return code: OK Number of successes: 10 Number of failures: 1 Operation time to live: Forever
IP SLA withTracking Configuration Step 3) now I will define the track number; and then later on I will append it to default route pointed to ISP1=192.168.12.2 R1# R1# R1#config t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#trac R1(config)#track 1 ? interface Select an interface to track ip IP protocol list Group objects in a list stub-object Stub tracking object
IP SLA withTracking Configuration R1(config)#track 1 ip ? route IP route sla IP Service Level Agreement R1(config)#track 1 ip sla ? <1-2147483647> Entry number R1(config)#track 1 ip sla 1 ? reachability Reachability state Return code state <cr>
IP SLA withTracking Configuration R1(config)#track 1 ip sla 1 re R1(config)#track 1 ip sla 1 reachability ? <cr> R1(config)#track 1 ip sla 1 reachability R1(config-track)#
IP SLA withTracking Configuration Here is show run so far track 1 ip sla 1 reachability ip route 0.0.0.0 0.0.0.0 192.168.12.2 ip route 0.0.0.0 0.0.0.0 192.168.13.3 50 ! ! ! ip sla 1 icmp-echo 192.168.12.2 frequency 20 ip sla schedule 1 life forever start-time now
IP SLA withTracking Configuration Step 4) now I go to default router that I had; remove it and add it with new track number 1 R1#config t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#no ip route 0.0.0.0 0.0.0.0 192.168.12.2 R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.12.2 ? <1-255> Distance metric for this route name Specify name of the next hop permanent permanent route tag Set tag for this route track Install route depending on tracked item <cr> R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.12.2 tr R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.12.2 track ? <1-500> tracked object number
IP SLA withTracking Configuration R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.12.2 track 1 ? <1-255> Distance metric for this route name Specify name of the next hop tag Set tag for this route <cr> R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.12.2 track 1
IP SLA withTracking Configuration So here is show run so far: r1#show run !track 1 ip sla 1 reachability ! interface FastEthernet0/0 ip address 192.168.12.1 255.255.255.0 duplex auto speed auto ! interface FastEthernet0/1 ip address 192.168.13.1 255.255.255.0 duplex auto speed auto !
IP SLA withTracking Configuration ! ip forward-protocol nd ip route 0.0.0.0 0.0.0.0 192.168.12.2 track 1 ( here I have added the Track) ip route 0.0.0.0 0.0.0.0 192.168.13.3 50 ! ! ! ip sla 1 icmp-echo 192.168.12.2 ( this is IP address of Main ISP1 that I am looking ) frequency 20 ip sla schedule 1 life forever start-time now !
IP SLA withTracking Configuration Now we will test it That is if ISP1=f0/0=192.168.12.2 goes down ; then when I go to R1#show ip route I will see the routing table has been changed to the new one ISP1#show ip int brief Interface IP-Address OK? Method Status Protocol FastEthernet0/0 192.168.12.2 YES manual up up FastEthernet1/0 unassigned YES NVRAM administratively down down FastEthernet1/1 unassigned YES NVRAM administratively down down
IP SLA withTracking Configuration ISP1#config t Enter configuration commands, one per line. End with CNTL/Z. ISP1(config)#int f0/0 ISP1(config-if)#shut ISP1(config-if)#
IP SLA withTracking Configuration Now I will go to R1#show ip route and see the routing table should point to ISP2=192.168.13.3 R1#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 192.168.13.3 to network 0.0.0.0 C 192.168.13.0/24 is directly connected, FastEthernet0/1 S* 0.0.0.0/0 [50/0] via 192.168.13.3 R1#

Cisco CCNA IP SLA with tracking configuration

  • 1. CISCO CCNA IP SLA withTracking Configuration To watch our Cisco CCNA Video Trainings Please Check out the link below: www.asmed.com/c1 ASM Educational Center Inc. (ASM) Where Training, Technology & Service Converge Phone: (301) 984-7400 Rockville,MD
  • 2. IP SLA withTracking Configuration
  • 3. IP SLA withTracking Configuration Now we will do Lab for Tracking In here we have as follow Above we have a router (R1) that is connected to two ISPs. We want to use ISP1 as the primary and ISP2 as the backup link. All traffic will be sent towards ISP1 but when it’s unreachable we’ll switch over to ISP2. You can achieve this by using two default routes: R1=f0/0 192.168.12.1 /24 connected to ISP1=192.168.12.2 R1=F0/1 192.168.13.1 /24 connected to ISP2= 192.168.13.3 R1#show ip int brief
  • 4. IP SLA withTracking Configuration Interface IP-Address OK? Method Status Protocol FastEthernet0/0 192.168.12.1 YES manual up up FastEthernet1/0 192.168.13.1 YES manual up up Serial0/1/0 unassigned YES Unset administratively down down

  • 6. IP SLA withTracking Configuration I will see the top commands on the routing tables R1#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 192.168.12.2 to network 0.0.0.0 C 192.168.12.0/24 is directly connected, FastEthernet0/0 C 192.168.13.0/24 is directly connected, FastEthernet0/1 S* 0.0.0.0/0 [1/0] via 192.168.12.2 R1#
  • 7. IP SLA withTracking Configuration Here R1 can ping both ISP and from above we see it prefer top ISP1 R1#ping 192.168.12.2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.12.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms R1# R1#ping 192.168.13.3 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.13.3, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms R1#
  • 8. IP SLA withTracking Configuration R1#show cdp neighbors Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone, D - Remote, C - CVTA, M - Two-port Mac Relay Device ID Local Intrfce Holdtme Capability Platform Port ID ISP2 Fas 1/0 136 R 7206VXR Fas 1/0 ISP1 Fas 0/0 143 R 7206VXR Fas 0/0
  • 9. IP SLA withTracking Configuration Now If I go to R1 and shut down the f0/0 (which is connected to ISP1) then since I have the Floating point the R1 #show ip route will be pointed to ISP2 R1#config t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#int f0/0 R1(config-if)#shut
  • 10.

  • 11. IP SLA withTracking Configuration As we see in above now R1 goes to internet via ISP2 , which is called the floating point---- But what happen if the link on ISP1 goes than ; then R1 in his table still will have original route to ISP1=192.168.12.2 so in here we will use the concept of Ip SLA with adding the track on the static route of R1
  • 12. IP SLA withTracking Configuration Lets bring up the int f0/0 on r1; R1#config t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#int f0/0 R1(config-if)#no shut
