Sure Gabriele,

I was just limiting the discussion to the coordination between edge nodes, but it applies also to core nodes.

Cheers
Daniele

Hi Daniele,

Also the case 2 in some conditions requires the Core nodes need to co-ordinate each other.
This is unless the edge node has the knowledge of the LSPs ERO

Regards,
Gabriele

Subject: [CCAMP] Question on LSP diversity

Hi,

bringing this to the list due to time constraints.

We said we have 4 use cases for LSP diversity:

-          1. Single homing

-          2. Dual homing

-          3. LSPs with different edge and core nodes

-          4. Multi domain

In cases 3 and 4 there is the need for "coordination" between edge nodes. Is such coordination in CCAMP scope or we assume that "somehow" the two edge nodes exchange such piece of info (e.g. NMS, the triangle with the eye, or whatever)?

BR
Daniele
