Multiple IPs for GRE over IPSec configuration

[zenta2000]

Hi ,

I have to configure two Cisco routers , working with tunnel interfaces for GRE encapsulation over IPSec.

One of the routers , has two external interface's IPs , the second only one interface.

How to configure both routers to work with different IPSec tunnels ? Router with one interface should understand that he's working towards ONE peer , but with two IPs . Decision of active IP , could be done by OSPF.

Thanx.

just replace the ip addresses with some other value and post them here.

tht would help to understand the current config and the way out to achive ur requirement.

Ok .

-- Cisco 1 -- IP=1

..........\ -- IP=2 --Internet -- IP=3 Cisco2 --

I need OSPF in GRE over IPSec between both routers ,

Cisco2 should decide which Cisco1 interface is active and route traffic towards it , till next failover , which will be discovered by OSPF.

In case when both Cisco1 interfaces are up , an active route will be chosen by metric or Rounf robin mechanism.

Thanx
