Hello,
Maybe someone can help out.
Trying to setup router on a stick setup for a 3550, having one issue with
the config though. I am able to make the same config work with a Cat5000.
In fact I can just pull cables from 3550 and plug into Cat5000 and it works
(after a couple "clear arp")s.
Am able to ping R7 to 3550, 3550 to R7, R7 to R1 and R1 to R7.
Unable to ping from R1 to 3550 or 3550 to R1.
Confiig:
BVI ISL vlan 20,21 g0/1 g0/3 access vlan 20

Just noticed the "spanning-tree extend system-id", I will try without it on
Thursday when I have access to the 3550 again.
Any other ideas would be appreciated.
TIA,
Tim
