Mike,
I can't find an official note on Cisco.com about this, but AFAIK you
can't assign a tunnel interface to a bridge group.
Not sure if this would help, but you could try routing DECnet between
both locations through a tunnel:
GW1_3640(config)#interface tunnel 0
GW1_3640(config-if)#dec
GW1_3640(config-if)#decnet ?
<0-3> ATG network number
access-group Set access control for outgoing packets
accounting Enable Accounting of DECnet traffic
cluster-holdtime Interval to hold PhaseIV VAX cluster adjacencies
congestion-threshold Congestion avoidance threshold
cost Set cost value for interface
hello-timer Set interval between transmitted HELLO messages
in-routing-filter Set up access control for incoming routing
information
multicast-map DECnet multicast mapping on token ring
out-routing-filter Set up access control for outgoing routing
information
route-cache Enable fast-switching of DECnet datagrams
router-priority Set priority for determining default router
routing-timer Set interval between transmitted routing
messages
split-horizon Enable split horizon on interface
Brgds,
Yasser

Subject: Bridge-group on a Tunnel interface?
Hello all,
I recently got a call from a friend at a firm with a very large network.
He has been tasked with bridging DEC protocol from one side to the
other. Again, this is a large routed network, so going to each routed
interface and making it part of a bridge-group would be not only a pain,
but almost impossible to get management to sign off on. So he wanted to
setup a Tunnel interface (on each end of course) then bridge from (say)
the ethernet interface on each side to the Tunnel interface. Problem
is, it appears the bridge-group command isn't available on Tunnel
interfaces...... Could this be an IOS thing that perhaps a newer
version supports, or is he just out of luck?
We even thought about trying to setup a PPTP or L2TP tunnel from end to
end.... any suggestions are welcome!
TIA,
Mike W.
