[j-nsp] NSRP through 802.1Q trunks

[Ivan c]

Doesn't seem to be the case though, even though logic would dictate
that the switch should just pass the frames....

I am starting to suspect that the Nortel do not recognise the frames
and thus are dropping it, as the HA interface MAC only appears on the
access port and not on the trunk port.

                  HA1                      dot1q trunk
       HA1
NS5400<------------------->5520<-------------------------->5520<------------------->NS5400

It would be helpfull if Juniper provided at least minimual detail on
the protocol.

Any Nortel ninja's out there?

cheers
Ivan
