I'm trying to establish simple plain GRE tunnel between two GSR boxes. No matter what I try, tunnel interface is up, while line protocol is down. I mean, how hard can it be to configure plain gre tunnel? On every other box it's working without problem, but not on GSR. Currently I'm running Service Provider 12.0.30(S5) IOS on both boxes, and config is really standard one: box 1 interface Tunnel0 ip address 10.1.1.1 255.255.255.252 tunnel source 10.2.2.1 tunnel destination 10.3.3.1 ! interface FastEthernet2/0 ip address 10.2.2.1 255.255.255.0 box 2 interface Tunnel0 ip address 10.1.1.2 255.255.255.252 tunnel source 10.3.3.1 tunnel destination 10.2.2.1 ! interface FastEthernet2/0 ip address 10.3.3.1 255.255.255.0 Both Ethernet interfaces are of course connected and ping works fine between 10.2.2.1 and 10.3.3.1. Also based on Cisco feature navigator this IOS supports GRE, so I have really no idea anymore. I would appreciate any hint, since I'm really without any further ideas about this.
