No blocked ports - Sub-second Network re-convergence - Well-known networking paradigm (link state)ĮCT (Equal Cost Tree) algorithm is used to find the best path during ECMP (Equal Cost Multiple Path) Network Efficiency Fast resiliency Simplicity SPB is a Spanning-Tree Protocol replacement for Ethernet and introduces: SPB Shortest Path Tree for BEB-1 to BEB-2 SHORTEST PATH BRIDGING (SPB) IEEE 802.1aq & RFC 6329 PROVIDER BACKBONE BRIDGE NETWORK (PBBN).Mostly beneficial for widely distributed network with mesh connectivity across multiple locations. This permits it to support much larger Layer 2 topologies, with faster convergence, and vastly improved use of the mesh topology without creating loops in the complex and most redundant connectivity network.Ĭombined with this is single point provisioning for logical connectivity membership, which includes point-to-point, point-to-multipoint variations.

Provides a clear separation of customer traffic (between different customers) and between the provider network domain The Alcatel-Lucent name and logo are trademarks of Nokia used under license by ALE.Ĩ02.1aq allows for most efficient shortest path forwarding in a mesh Ethernet network context utilizing multiple equal cost paths. Transparently extends Layer 2 domain (VLAN segments) across a large virtual service Layer 2 backbone network. Maintains a loop-free network while providing efficient use of available bandwidth Uses 802.1AH standard for MAC-IN-MAC encapsulation(SPB-M) Why do we need SPB?

Spb protocol how to#
The snippets below show you how to configure OSPF on the ASA and an Avaya VSP. You can actually use a routing protocol between your Avaya SPB network and the Cisco ASA. It’s been around for a really long time, and in my experience, is very reliable.įar too often, people just configure an ASA with a bunch of static routes to their internal networks , one default route to the internet, and call it a day. Naturally, you would need to protect your network from intruders.A great firewall product for this purpose, is the Cisco ASA. If you have an SPB network, at some point you’ll need to connect to the internet or some other external network.
