GRE tunnel betweent frame-relay and atm

[paublo]

Hi, i'm trying to get a tunnel up between a frame relay router and and 827 cisco atm router.

both tun des/source gets replies from both sides of the the tunnel. But i can't seem to be able to 1. ping the tunnel ips within each router and 2. route traffic across it. I'm really not sure what im doing wrong.



here is the config.

interface Tunnel0
ip address 172.100.0.6 255.255.255.252
no logging event subif-link-status
tunnel source xx.xx.xx.130
tunnel destination 172.100.0.2

ip route 10.16.27.0 255.255.255.0 172.100.0.5

interface Tunnel0
ip address 172.100.0.5 255.255.255.252
tunnel source 172.100.0.2
tunnel destination xx.xx.xx.130
!

ip route 10.16.20.0 255.255.255.0 172.100.0.6

Type escape sequence to abort.

problem was, that tunnel encaps were not matching on the ATM cisco 827 side, even though it was set for GRE it didnt show as a gre tunnel when i did sh int tun0.

i changed it to ipip encaps for the tunnel and both sides came up.
