Hello Group,
Below are my configurations on cat3920. Routers are attached using ports as per
the CDP info. TrBRF's were defined with corresponding TrCRF's under it. Ports
are then assigned to TrCRF's accordingly.
When SRB bridging mode is used on TrCRF's, why is it that ping from r3 to r8 is
unsuccessful ??? But when I changed the bridging mode to SRT I was able to pin
g r8 from r3. Is there a way to make it work using SRB on TrCRF's ??? I'm kind
of confuse about those bridging mode.
Appreciate any feedback.
Thanks,
Neil
