Hello,
I'm trying to setup a gre tunnel over my mpls network in a VRF called Intra. Here is my conf. It's weird because the tunnel protocol is up on one side, down on the other side.
I can ping the destination ip address on each side.
interface Loopback30
ip vrf forwarding Intra
ip address 192.168.252.80 255.255.255.255
interface Tunnel1
ip vrf forwarding Intra
ip unnumbered Loopback30
keepalive 3 3
tunnel source Loopback30
tunnel destination 10.10.40.1
sh int tunnel 1
Tunnel1 is up, line protocol is down
Hardware is Tunnel
Interface is unnumbered. Using address of Loopback30 (192.168.252.80)
MTU 1514 bytes, BW 9 Kbit, DLY 500000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation TUNNEL, loopback not set
Keepalive set (3 sec), retries 3
Tunnel source 192.168.252.80 (Loopback30), destination 10.10.40.1, fastswitch TTL 255
Tunnel protocol/transport GRE/IP, key disabled, sequencing disabled
Tunnel TTL 255
Checksumming of packets disabled, fast tunneling enabled
Last input 00:00:00, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 421
Queueing strategy: fifo
Output queue: 0/0 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec

one command is missing
"tunnel vrf Intra" on the first device.
07-07-2008 10:37 PM
The command does not exist on that one (6500 12.2)

You should upgrade IOS on the 6500
I have such command with 12.2(33)SXH2

Ok thank you, i'm in 12.2(18), that should be the problem !

If you can't put "tunnel vrf" command in router A tunnel , that's not works , "tunnel vrf" command for it uses the tunnel destination and source addresses from the routing table of VRF
is not set the tunnel destination is unreachable, tunnel use backbplane routing table..
