I have configured two site to site vpn on the two routers. The core switch is connected to vpn router. To avoid configure lots of static route I configured the reverse route on both sides. From the test It looks like i need to configure some staic route or default route on core switch or route the traffic to the vpn router and then it will trigger the rri works. With out those static or default route, it looks like the RRI did not inject the route into the core switch.
i have eigrp configured between the router/switches. the problem is i do not want the default route to point to the vpn route at all. If I configure the static route, then why i need the rri..
So my question is how to let the RRI works once it is configured. If it works right away the core switch will receive the route and do not need to configure the static route at all
Thanks for your reply. The default route should not go to vpn router, otherwise any traffic to the internet has to go to the vpn router-http etc.
From my lab test it looks like with "reverse route static" will create the static route on the vpn router permanatlly and then redistribute into the eigrp.ospf. By this way the core switch will receive the customer subnet route to point to the vpn router then.
