Join us for the next Cisco TechAdvantage Webinar, a 2-hour technical discussion on the benefits of Layer 2 VPN (L2VPN) in the Data Center. This webinar will describe the motivation for using IP/MPLS technologies as a Data Center inter-connect technology.
Data Center Interconnect is a service that Service Providers (SP) can offer to interconnect Enterprise Data Centers, interconnect SP Data Centers, or allow Enterprise to connect to SP-owned compute and storage resources.
We will discuss:

Many thanks for the great documen
I have few questions please regarding A-VPLS. Appreciate If you can assist
@ Slide 22 -- For part C IP/MPLS
1- P router has to use port-channel so it can calculate a hash based on the flow label, correct ?
2- Also I should configure "port-channel load-balance mpls" at P router, correct ?
3- If I am correct, flow label should be the 3rd label and according to command reference for "port-channel load-balance label" only last 2 labels are taken into considersation !?
------------Quote----------
v If you select label, these guidelines apply:
• With only one MPLS label, the last MPLS label is used.
• With two or more MPLS labels, the last two labels (up to the fifth label) are used.

Q1: P router has to use port-channel so it can calculate a hash based on the flow label, correct ?
A: If you are refering to the 6500 VSS then it is a PE router but you are partially correct first you need to configure "load-balance flow" at the PW level after you configure "flow-label enable" that will enable load balncing on ECMP. the "port-channel load-balance <method>" command does not recognise the flow label but mac-addresses, IP addresses, ports and L2 mpls label.
Q2: Also I should configure "port-channel load-balance mpls" at P router, correct ?
A:no necessarely you can load-balance on any supported algorithms supported
Q3:- If I am correct, flow label should be the 3rd label and according to command reference for "port-channel load-balance label" only last 2 labels are taken into considersation !?
A: the port-channel does not use the flow label for load balancing
A-VPLS uses the etherchannel load balancing and the flow label load balancing techniques indepedently.
Hope I answered your question
