as explained in 8.1, it's a two step logic; First step is based on destination mac only. STP destination mac is 01-80-C2-00-00-00, so for EP-LAN, table B applies, which reads "must tunnel". Second step (table F in 8.1.3) only comes into play for destination macs 01-80-C2-00-00-01 through -0A and 01-80-C2-00-00-0E, but STP does not run on those macs at all normally so only step 1 applies. and note this document only applies to L2CP with destination macs in the 01-80-C2-00-00-00 to -0F range. E.g. for Cisco and others proprietary stuff using other macs you can do whatever you please. -- Daniel. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
