Shadow MPLS port concept

[abhishekatulip]

Hi

A client has asked for 'shadow MPLS port" for their DR site. This query is not very clear. following is the scenario:

They have two service provides (VPN). They want to have links from both service providers (they will be primary at some locations and backup at some locations). They have their DC and DR in place. What they want to know is about the concept of using 'Shadow MPLS poer" at their DR site.

Can any one help please.

You have to use VLAN subinterfaces on the core facing interfaces and hence to set up the shadow in the context of MPLS-VPN for their specific design guidleines this would mean to use a dedicated port, defined as an extra-net and connected to the 12k.
