Add "Tunnel mode " at your config  :-)

Subject: [c-nsp] GRE tunnel on GSR

Hi guys

I guess I'm missing something obvious here, but I really have no idea
anymore. 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.

Have fun,
