Two firewalls are connected in Active-standby mode and tracking the inside and outside interfaces. There is a connectivity from router to the primary firewall portX and router is used for reaching the backoffice locations.Here my problem is whenever the firewall failover happens i lost connectivity to the backoffice networks from my inside network of firewall. So is ther anyway to configure the Cisco router with redundant interface like if the interface (connected to primary firewall) goes down, traffic should automatically pass through some other port and it should be connected to standby firewall portX.
You can use IP SLA to change your routing such as default route, PBR, etc. You can find tons of Cisco documentation and examples if you search for them. Otherwise you can read the post below directly from this community:
Here one problem is there for using the IP SLA. I don't have two next hop IP's, only one is there(firewalls are in HA. So same config is there in active and standby FW). Can you suggest how can i proceed in this.
What about using the hop after the next as the IP SLA destination interface, like a switch they are plugged in to? For the reachability you can have it track google if you want...
In my scenario it will not work. Router interfaces are connecting to both the active firwall and standby firewall. Standby firewall remains idle until there is problem in active firewall. Standby firewall is having the replica config of active firewall. So we cannot mention two static routes. If you have any suggetions please let me know.
