Hi everyone,
I have an issue that I need to confirm how to resolve.
I have an alcatel 6850 switch connected to a 3750. Two connections (cables) are used between the switches. The two connections from the alcatel are in different vlans 10 and 60 , but the cisco ones are in the same vlan ie 1 (I know not best practice but keep with it ).
The cisco cables are connected into port 1 and 4. Port 1 is forwarding and 4 is blocking.
The 3750 is configured with basic default pvst configuration.
The alcatel is the root bridge.
As can be realised traffic from alcatel on vlan 10 cannot pass traffic to the 3750, This was established by the spt seeing the same mac from the root bridge therefore blocking port 4.
To stop this from blocking in this scenario I was going to use bpdufilter. Any ither suggestions would be helpful thanks.
Cheers
Tony
