Submitted Dec 16, 2009 by einval
Rapid per-VLAN spanning tree capture of a trunk port, configured with native VLAN 5, VLAN 1 is also active over the trunk.
Capture shows that 3 BPDUs are sent out, one for classic STP (Frame 4, for example), one for the native VLAN 5 (not tagged - Frame 5) and one for each other active VLAN (tagged - Frame 3).
The PVST BPDUs contain the VLAN ID at the end of the frame (01 and 05, respectively).

Submitted Oct 12, 2009 by pierky
Routers at 1.1.2.1 and 1.1.2.2 are PEs in a MPLS cloud. LDP starts at packet 8 and they build up a pseudo-wire VC (last FEC in packets 11 and 13). At packet 15 we already have STP running between CE1 and CE2 (two routers with ESW), encapsulated in 2 MPLS headers. All the ethernet stuff follows: CDP, ARP, ICMP between two hosts on the same subnet.
