We have two cisco 837 routers (R1 & R2) located at our main office. Another cisco 837 router (EA) is located at remote office.
There are two tunnel interface configured. tunnel1 connects R1 and EA routers. Tunnel2 connects R2 and EA routers.
Static route table is configurate as follow:
In R1: ip route 18.104.22.168 255.255.255.0 Tunnel1 In R2: ip route 22.214.171.124 255.255.255.0 Tunnel2 (Where 126.96.36.199 is remote office network address)
In EA: ip route 188.8.131.52 255.255.255.0 Tunnel1 ip route 184.108.40.206 255.255.255.0 Tunnel2 5 (Where 220.127.116.11 is main office network address)
Usually everything works right. Both tunnels are up and we can connect to EA throught either R1 or R2.
Problems begins when adsl connections at R1 fail. We think EA must detect that tunnel1 is down and route trafic over Tunnel2, but EA didn=B4t route over tunnel2 until we manually shutdown tunnel1.
Can you help me about this?
