Cell mode MPLS

After all this is not so hard.
Going to describe only ATM realted stuff here:

Main issues:
1. ip routing information
2. control pvc (used to exchange ldp/tdp information, igp adjancencies)
3. label distribution protocol (tdp/ldp) - defined globaly, can by changes per interface basis
4. ip cef (cometimes c7200 looses it - on dynamips probably)
5. mpls forwarding table (atm uses PVCs insted of mpls tags)
