Hi all, need a little help !
As per attached diagram, I have configured 'reliable static routing' to route between two different ISP'S and internet connections. This gives the user some resillience when connecting to a remote server (AS400).
The problem I have is when a user has a session open on the remote server (AS400) using telnet or IBMS client software, the sessions drop during a failover to the secondary link and they have to re-connect.
Reliable Static Routing is configured on both routers in the diagram which track (poll) each others f0 interfaces. If the routers cannot see each other, they instantly point their default-gateways at the secondary firewall each end.
Failover appears to take 3-4 seconds and tunnels on both primary and secondary firewalls are contstantly active.
Im trying to find out why the user sessions are dropping during failover and what config I could possibly put in place on each cisco router to help prevent sessions dropping.
One of my routers configs .
