Re: encapsulation failed? forus FALSE? sendself FALSE? Huh?

I'm using a proctorlabs rack. S1 is a 3550. Everything is using SVIs.

3550 - 12.2.(44)
and
3560s - 12.2.(25r)SEC

The tasks of the lab require one instance of spanning tree (MST 0) so all my
vlans are going from S2 to S1. If I tamper with the cost of the interface, I
can bring up the S2 to S4 leg but I kill the S2 to S1 leg. So I can make it
work but only by sacrificing another path.
