[HECnet] GRE

[Dave McGuire]

  Brian, I think the best way to approach it is to just try this:

interface Tunnel1
no ip address
decnet cost 10
bridge-group 1

  Sometimes the simplest approach is best. =)   Offhand I don't see why that wouldn't work.

  Another possibility might be to to just bridge everything across the tunnel, then use ACLs to filter on EtherType (DECnet Phase IV is 0x6003):

access-list 200 permit 0x6003
...
interface Tunnel1
  no ip address
  bridge-group 1 input-type-list 200     # or output-type-list?www

                    -Dave
