A friendly competition among presenters Help @punbehagen win Easy to remember name @randy_cross? Too forgettable Tweet this session with #AvayaATF and #SDN You could win a iPad Mini… If you don’t have a twitter account… Get one, you can delete after the show Help me WIN by coming to my other sessions (and Tweeting!)

All rights reservedFebruary 26-28, 2013 | Orlando, FL SPB’s Forwarding Model Multicast traffic originates at Edge-1. One multicast packet sent to Core-1. Replication done at optimal point based on shortest path algorithm Edge-1 Edge-2 Edge-4 Core-2 Core-1 Edge-5 Edge-6 Edge-8 Edge-9 Common VLAN service Packets only traverse SPF links, no out of order packets, only nodes that are a member of the same service receive packets Edge-3 Unicast and Multicast always follow the same path No intervention needed, no root bridges, just turn it on VLAN evolves into a Service with simple end point provisioning All traffic is forwarded in the most optimal path based on SPF calculations 20

21 ©2013 Avaya Inc. All rights reservedFebruary 26-28, 2013 | Orlando, FL©2013 Avaya Inc. All rights reservedFebruary 26-28, 2013 | Orlando, FL Multicast traffic originates at Edge-1. One multicast packet sent to a root bridge. Replication NOT done at optimal point, but to the SPF to the root bridge Edge-1 Edge-2 Core-2Core-1 Common VLAN service TRILL’s Forwarding Model Problem unicast and multicast can take different paths Root Bridge Edge-3 Edge-4 Edge-5 Edge-6 Edge-8 Edge-9 Unicast can take a different path, risking reordering packets In Trill model, unicast and multicast take different paths 21

22 ©2013 Avaya Inc. All rights reservedFebruary 26-28, 2013 | Orlando, FL©2013 Avaya Inc. All rights reservedFebruary 26-28, 2013 | Orlando, FL Multicast traffic originates at Edge-1. One multicast packet sent to Core-1. Packets sent to non-service participating nodes, just to be dropped Edge-1 Edge-2 Core-2Core-1 Common VLAN service TRILL’s Forwarding Model Problem the solution is worse then the original problem… Make every edge a ROOT Bridge! Root Bridge Edge-3 Edge-4 Edge-5 Edge-6 Edge-8 Edge-9 To get best multicast model they have to make every edge a root bridge Lots of manual config of where root bridges exist Causing every edge to receive a packet whether it has a service or not 22

With TRILL, no two vendors implementation is the same; no multi-vendor interoperability!! 30
