[toc:faq]The ProblemOn traditional switches whenever we have a trunk
interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...

Sup32 that allows one to capture packets on the RP or SP inband. The

network. From this picture each router independently runs the Shortest
