Hi all,
What is the recommended way for tackling PVST+ BPDU flooding through a SPB network?
There is a use-case where three (3) switches are connected to two (2) BEBs and PVST+ BPDUs need to:
1. be allowed on the UNI ports
2. be allowed to be flooded through the BEB NNI interconnection of
PVST+ is needed to offer uplink redundancy to the CISCO switches and have loop avoidance.
The fabric facing design is the following:
CISCO SWITCH1 --> BEB-SW01 UNI PORT 1
CISCO SWITCH2 --> BEB-SW01 UNI PORT 2
CISCO SWITCH3 --> BEB-SW02 UNI PORT 1
BEB-SW1 NNI PORT X <--> BEB-SW2 NNI PORT X
Each UNI port will have multiple VLANS each mapped to their own ISID.
There are multiple other BEB/BCB switches which currently work for the VLAN-ISID mappings as expected and are pure fabric based.
Any recommendation is more than welcomed.
Thank you
Best Regards
Konstantinos Betsis
