3.1.2.15. Provider Backbone Bridging (IEEE 802.1ah)
Provider Backbone Bridging (PBB), also called MAC-in-MAC, supports larger
networks by encapsulating frames in the network. By hiding the MAC addresses, it
enables scalability of the backbone network.
The PBB of this product supports the followings:
IB Component
Customer network port matching S tag, C tag, or any frames
Point-to-point connection
One backbone MAC address
Since multicast is not supported, PBB networks can not have more than three BEBs
that use the same I-SID.
