HSRP and tracking

[Amos Kafwembe]

hello all.

I have dual ISP's comming into my network on two different routers. i have configured HSRP on my gateway router to failover if any of the tracked interfaces go down. How ever, there are instances where we lose internet connectivity upstream (not that the interface has failed or gone down) and in these cases the failover doesn't work.

is it possible to track eg, pings to google, such that, should pings fail HSRP should failover?

Dear Amos,

Can you post the config removing sensitive areas and have you included tracking interfaces in your config

You can configure it using IP SLA to check the ping reachability to the ISP IP address

track 10 ip sla 123 reachability
 delay down 10 up 10

ip sla 123
 icmp-echo x.x.x.x

ip sla schedule 123 life forever start-time now
 
Calling this track in hsrp
standby 1 track 10

take a look below.

(config)#ip sla ?

  key-chain  Use MD5 Authentication for IP SLAs Control Messages

  responder  Enable IP SLAs Responder

  server     IPPM server configuration

what should i do....??

what version of IOS are you using? is it the same as the one in the "show vwersion" i pasted earlier?

[patrick.preuss]

Hi

Can you please provide a Show Version. Ip sla has changed over Time. Old Versions May know rtr and track as commands.
