I have an existing VPN 800 series router that is connecting to a 7600 series fine. crypto ISAKMP reaches the QM_IDLE state. RRI is enabled and the reverse route is being injected into the 7600. The problem is there is an additional route on the 7600 pointing to the IP this VPN connected yesterday and I cannot clear it out.
7600 - sh ip route static (my vpn network IP's are changed for security purposes)
S 126.96.36.199 /29 [1/0] via 188.8.131.52 << THIS WAS THE VALID ROUTE YESTERDAY
[1/0] via 184.108.40.206 <<THIS IS THE VALID ROUTE
When I clear the route: clear ip route 220.127.116.11 255.255.255.248
S 18.104.22.168 /29 [1/0] via 22.214.171.124
This route will not clear out of the routing table. After I reset the VPN session the valid route is re-inserted but the 126.96.36.199 destination will not remove from the routing table.
Here is a ping to my network across the VPN
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 188.8.131.52, timeout is 2 seconds:
. ! . ! .
Success rate is 40 percent (2/5)
This is obviously due to the router attempting to load balance across the 2 static routes.
I have debugged the route: debug ip routing static route 184.108.40.206 255.255.255.248
and the invalid route updates the same time as the valid route. I have reviewed the configs on the local (7600) and the remote (800) routers and all is good.
Any thoughts on how to clear the invalid route or determine where it is coming from? I have 4 other VPN routers that are connected and operational.
Thoughts, comments, solutions?
