Re: [c-nsp] TCN's - Causing brief outages on ASR1K

Switches can have rate-limiters (aka storm-control measures) to control broadcast, multicast and unknown-unicast. BPDU's are layer-2 multicast. Your issues sounds like you're losing BPDUs. Try "debug spanning-tree root" to see if it's causing root changes. If you are running a lot of VLANs wort

Re: [c-nsp] Understanding ASR1k / ESP40 capacity
