Righto. Apologies for the 2-3 short storms this morning between 9:30am-10am, that was me :-(. Specifically, I reenabled Quest's port, and everything went pearshaped. From what I can gather, this is because United are offering circuits with redundant VLAN's that assume that the connection at the end is going to provide spanning tree blocking. Spanning tree was turned off on the Citylink APE switch, so as soon as they were plugged in, boom, it all went yucky. That being the case, I've taken Kevin(a)Telecoms suggestion, and renabled spanning tree on the APE vlan, with a priority of 10, which means it should win all ST elections, and become the root of spanning tree on APE. That has fixed the United problems, Quest appear to be running fine, I'd be interested to know if the Netgate/Mercury problems are improved, and also if the Tangent circuit for Attica can be made to work.

IGMP, I wouldn't have thought so, CGMP, probably. Worst case, I guess I could do it by hand, and assign each port to a multicast VLAN. (Sez me, knowing little about vlans, less about multicast, and nothing about IGML and CGMP :-).
CGMP (when I had it turned on) has a source MAC of the thing sending them (funny that), ie the routers. So MAC filtering shouldn't break it. And having CGMP enabled is probably a good thing, because it'll stop peoples links getting flooded with other peoples multicast pr0n streams.
