HSRP -Tunnel Configuration

[cemrecanaltinel]

Hello, in my central structure, there are 2 routers on which I apply hsrp, and I set up a Gre tunnel between the router in the backup center and the active router in the center, and the 2 routers talk to each other. There are static routes on each router to access the vlans behind the routers. My configurations are as follows;
Active Router-Main
interface Tunnel20
ip address 192.168.80.1 255.255.255.224
ip mtu 1400
ip tcp adjust-mss 1360
tunnel source GigabitEthernet0/0/7
tunnel destination 10.82.46.20

backup router
interface Tunnel20
ip address 192.168.80.2 255.255.255.224
ip mtu 1400
ip tcp adjust-mss 1360
tunnel source GigabitEthernet0/0/2
tunnel destination 10.82.46.56

Active router static route;192.168.20.0(backup vlan side) 255.255.255.0 192.168.80.2
Backup Router static route:192.168.10.0(main vlan side) 255.255.255.0 192.168.80.1,

My hsrp configurations are correct and both routers use the same interfaces. I want the traffic to pass to the passive router if the active router is down. I will create a new tunnel between the passive router and the router in the backup center, that's for sure, but what kind of static route should I write for the passive router and the backup router? Does this work?

where is your HSRP Configuration, can you show how your high level network diagram looks like ?

you looking tunnel failover you can do different methods or tracking the interfaces or using any IGP so on..

Hello,

if you need to use static routes, you could simply configure routes that track IP SLAs...

BTW, for ordinary GRE, you only need to allow for 24 bytes overhead.
