You mentioned "create a vlan with a TrBRF type SRT". In Catalyst 3920,
bridging mode (SRB/SRT) is specified in each TrCRF not in TrBRF. So we can
have the TrBRF doing SRB for TrCRF1 and SRT for TrCRF2.
To eleborate my initial question, if we have two hosts (Token Ring routers),
says R1 and R2. R1 is connected to TrCRF1 and R2 is connected to TrCRF2.
TrCRF1 and TrCRF2 are connected to the same parent TrBRF. We will leave the
bridginging mode as default (SRB) on both TrCRFs.
R1 ip is 172.16.0.1/24.
R2 ip is 172.16.0.2/24.
Can R1 pings R2? Why?
Now change both briding mode from SRB to SRT.
Can R1 pings R2? Why?
Next step is to enable "multiring all" on R1 and R2. Try the same test, what
will happen?
Thanks!
5 days left..
