[HECnet] HECnet GRE Tunnels...

[Mark Darvill]

It would probably be worth working out again who is using GRE and redefine and re-establish all of the tunnels.

GRE works well for me as it is always on and there when I need to use it.

The tunnels I can see and am peering with are:

0   12.1023  Tunnel57             0000.0000.0000 A 
0   23.1023  Tunnel59             0000.0000.0000 A 
0   42.1022  Tunnel51             0000.0000.0000 A 
0   61.1023  Tunnel53             0000.0000.0000 A

I am routing to the rest of HECnet through area 12 currently and can decent ping mim:: 1.13

My tunnel IP is 81.138.115.178 and am happy to peer with anyone else using GRE. The IP 81.135.164.245 is my current dynamically assigned address so Tim, probably better if you switch to 81.138.115.178 as it will likely change.
