Hi all,


Is it possible to provide redundancy for a L2 MPLS VPN Customer between his two sites. ( I thought of having a parallel pseudowire link and run any routing protocol between his CE's). Apart from this any other possibility of providing redundancy??



Thanks in advance....

Arun, depending on your SLA to your customer you can choose the appropriate method for redundancy. The method which you have proposed if also fine.


Here is a feature called L2VPN pseudowire redundancy where in only one pseudowire would be active for the customer at a time just like what you have in opticals called protection circuits.
