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)

Copy IOS files via ftp
sometimes is not very easy to copy file to router's flash using ftp.
For example source interface (ip address) problem. this can be tuned using commands:
ip ftp username
ip ftp password
no ip ftp passive
ip ftp source
after that:
