I have enquries for the interface tracking to the WAN connection. Below is the case scenario.
I have 2 routers (router A and router B) that running HSRP with OSPF connect to remote side router (router C and router D) seperately. If the interface for router C or router D go down, either router A or router B will become Primary router by using the tracking interface feature. Gig0/0 is the connection to WAN and gig1/0 is the connection to LAN. Not sure whether the configuration below is correct. Please feel free to input any comment. Thank you.
However the config may not meet your requirements as the tracking only monitors the physical router interface, so if there is a switch etc between router A/B and the WAN, this would effectivly mask the WAN or router C/D going down. It is dificult to say though without knowing the topology!
Yes the idea here should work. You have missed 1 important part of the config on Router B, I have highlighted this in the configs below
Router A will be the gateway on 220.127.116.11 until its G0/0 goes down. Router B will take over.
Because you are using the PREEMPT command Router A will take over as soon as G0/0 recovers. So the Router B will not hold the address until its G0/0 goes down. To me I dont see any point in tracking G0/0 on Router B as it should never be active untill RouterA has a failure
Router A ! interface GigabitEthernet1/0 ip address 18.104.22.168 255.255.255.0 no ip redirects standby 1 ip 22.214.171.124 standby 1 priority 105 standby 1 preempt standby 1 track GigabitEthernet0/0 !
Router B ! interface GigabitEthernet1/0 ip address 126.96.36.199 255.255.255.0 no ip redirects standby 1 ip 188.8.131.52 standby 1 preempt standby 1 track GigabitEthernet0/0 !
Use the "show standby brief" command to verify that the HSRP is in active & standby mode on both routers A & B
Router A should be active Router B should be in standby
