[c-nsp] Inter AS MPLS hybrid thingy...

[JC Cockburn]

Hi Oli,
You understood correct.
So one of the ways is to get another (logical/physical) link from Child_net1
to Parent_net and do Inter-AS MPLS over that link...can be the same physical
routers. Option 10b would be the best to suite our requirements as the
number of L3VPN's might grow...

Thanks guys
Ciao
JC

Yes, so I read it as well.. But I guess the question is how Child_net1 wants
to interconnect with a L3VPN (not CsC) customer on Parent_net.. If
Parent_net just imports the L3VPN customer's Routes into the CsC VRF towards
Child_net (and vice versa), this would provide connectivity between
Child_net's global table and the L3VPN customer. But not (and this is how I
read it) between a Child_net L3VPN customer and the L3VPN customer on
parent_net..
So enough speculating, let's wait for JC to clarify the requirements :-)
