April 11, 2016

Shortest-path-bridging is increasingly expanding its reach beyond the data center and is providing network administrators a new alternative for service separation, while at the same time reducing or eliminating the use of spanning tree in their networks.

What is shortest-path-bridging?

Shortest path bridging is an open standard supported by multiple vendors and is fully described in IEEE 802.1aq. in essence, it uses MAC-in-MAC encapsulation in the data plane and IS-IS in the control plane to provide loop-free separation between services in a network.
