[c-nsp] IGX over MPLS

[Manaf Oqlah]

Thanks Dave,
I think this is what I want. But could you please send me a sample
configuration for the IGX Virtual Trunk and router ATM interface.

Regards,
Manaf

Manaf,

	You need to look at AToM on the routers (specifically you need ATM
VP trunking, NOT VC).  Only certain revisions of IOS support VP trunking -
mostly in the 12.0S train (don't think they've ported it to 12.3T
yet/or
are ever going to)...

On the IGX you'll need to set up virtual trunks, which creates a trunk
that works like everything else but it does it over a single VP.  The
routers then take this VP and trunk it over the MPLS network.

It's relatively complicated the first time you set it up but once it's up
and running it's pretty simple and relatively easy to troubleshoot.

If you want some more detail get in touch with me off-list.   I set this
up about a year and a half ago.
