[HECnet] Issues With Virtual Cisco Tunnels and HECnet

Hello, all! Dave and I have been attempting to establish a link between us using dynamips on my end, and real cisco gear on his end and we've hit some issues. The GRE tunnel comes up fine, I can ping DECnet nodes on his end, and I can set host to nodes in his area. It is also possible for nodes in his area to reach nodes in my area so packets are indeed getting /somewhere/. However! Despite this tunnel being identical to the other tunnels, I am unable to reach the rest of HECnet via the tunnel to him. Here's the output of SHOW DECNET ROUTE: --- marianne#sh decnet route Area Cost Hops Next Hop to Node Expires Prio *1 16 3 Tunnel0 -> 61.1 *2 16 3 Tunnel0 -> 61.1 *3 19 4 Tunnel0 -> 61.1 *4 16 3 Tunnel0 -> 61.1 *5 16 3 Tunnel0 -> 61.1 *6 16 3 Tunnel0 -> 61.1 *7 18 4 Tunnel0 -> 61.1 *8 16 3 Tunnel0 -> 61.1 *9 0 0 (Local) -> 9.1023 *11 16 3 Tunnel0 -> 61.1 *12 16 3 Tunnel0 -> 61.1 *18 17 4 Tunnel0 -> 61.1 *19 16 3 Tunnel0 -> 61.1 *20 17 4 Tunnel0 -> 61.1 *28 16 3 Tunnel0 -> 61.1 *33 17 4 Tunnel0 -> 61.1 *42 15 2 Tunnel0 -> 61.1 *44 16 3 Tunnel0 -> 61.1 *47 18 4 Tunnel0 -> 61.1 *51 18 4 Tunnel0 -> 61.1 *52 15 2 Tunnel0 -> 61.1 *59 15 2 Tunnel0 -> 61.1 --- And ping: --- marianne#ping 61.1 Type escape sequence to abort.
