1. The ATM-LSR switches cells based on the VPI/VCI value in the atm header.
The switching mechanism is the same as traditional ATM cell switching, and
the MPLS label allocation/distribution methods are responding for binding
those inbound/outbound VPI/VCI mappings.
The ATM edge-LSR can do the same function as the ATM-LSR but can also do IP
lookups.
2. Yes, the control channel for TDP or LDP is 0/32 (must be aal5snap)

Subject: Routing of cell mode MPLS
Hi, I need some clarification on how the cell-mode
MPLS operates.
1. Does the MPLS stack of the ATM-LSR maintain a IP
routing table?
2. Does a ATM-LSR use VC 0/32 to exchange IP routing information?
Thans!
