How are VLANs annoying? Bridge configuration can partition the cloud (“I’ll use ‘LAN’) if data is tagged with VLAN A, but not if tagged with VLAN B, for some values of A and B We don’t want to have multiple DRBs on the LAN You conclude you are DRB if you hear no other IS-IS Hellos, so bad if send Hellos on partitioned VLAN So…what VLAN tag do you use when sending Hello? |
