EIGRP and GRE

[jgmitter]

I need to pass EIGRP and IGRP through a gre tunnel through a pix! The tunnel is up through the pix and with show ip route: i see the route for the tunnel. however, I dont see the other routes for the other remote networks! any thoughts on what I am missing with this config! I also have neighbor statements pointing to each tunnel interface

Router2

interface Tunnel10

ip address 10.1.2.1 255.255.255.0

tunnel source Ethernet0/0

tunnel destination 10.1.3.1

!

interface Ethernet0/0

ip address 10.1.1.1 255.255.255.0

full-duplex

Router 1

interface Tunnel10

ip address 10.1.2.2 255.255.255.0

tunnel source Ethernet0/0

tunnel destination 10.1.1.1

!

interface Ethernet0/0

ip address 10.1.1.1 255.255.255.0

full-duplex

take a look at this. Its about multicast but i think it applies.

this is the exact doc I used to get this far! the tunnel is up, but not seeing routes passed through!

Could you ping the interface tunnel frome each other?

The configurations you provided have same ip address on ethernet port.

Do some tests to confirm the cause of the problem, tunnel or multicast?

I cant ping the destination tunnel interface!

Do your routers know how to get to the tunnel destination?

If the Ethernet interfaces in your config the ones that connect to the firewall, you may have to put static routes like so:

Router 1

ip route 10.1.1.1 255.255.255.0 10.1.3.2 (or whatever the firewall IP address is)

Router 2

ip route 10.1.3.1 255.255.255.0 10.1.1.2 (or whatever the firewall IP address is)
