Here is the response I got from Jim Guichard, the
author of the book "MPLS and VPN Architecture".
> >1. Does the MPLS stack of a ATM-LSR maintain a IP
routing table? If so,
> >what kind of routing protocols does it support?
I can only really comment on Cisco equipment. The
ATM-LSR has an LSC attached (Label switched
controller). The LSC is basically a router with an
interface to the ATM-LSR. It runs the routing
protocols and instructs the switch to setup the
cross-connects for each LVC. Any routing protocol
should be fine.
> >2. Does a ATM-LSR use VC 0/32 to exchange IP
routing information?
no. The edge LSR using 0/32 to exchange information
with the LSC rather than the ATM-LSR ..
Hope this helps. Jim
