[c-nsp] Bridging ethernet to MLPPP

[Joe Freeman]

I've got a situation where a customer is having to relocate from one
facility to another a few  miles away. This customer has a 100Mb metro
ethernet connection at the old location, and can't get it moved for several
months.

To help them out, we're trying to setup a pair of 3620's that we had with
wic-1dsu-t1's (4 ea router) to bridge the metro e across a multilink ppp
group and back to an ethernet connection at the new site.

For some reason, I can't get this to work. Here's the config I'm using on
each side-

bridge irb
bridge 1 protocol ieee

int serial 0/0
encaps ppp
multilink-group 1
int serial 0/1
encaps ppp
multilink-group 1
int serial 1/0
encaps ppp
multilink-group 1
int serial 1/1
encaps ppp
multilink-group 1

int multilink 1
encaps ppp
bridge-group 1

int fa0/0
bridge-group 1


So I figure I'm either missing something simple, or something major, like
it's just not possible with this hardware. Either way, I'd appreciate
whatever thoughts anyone has.

Thanks-
Joe
