Re: [j-nsp] Tricks for killing L2 loops in VPLS and STP BPDU-less situations?

One think I noticed when working with the BUM filter under VPLS instance is that there is no way to declare a per instance policer that I could find. Your can call the same filter/policer in multiple VPLS instances, but the named policer is a single global instance. So, if you call the same

We have had the unfortunate experience of having users plug in small mini-switches into our network that have the capability of filtering out (by-default) BPDUs while allowing other traffic through. The nightmare situation is when a user plugs in such a switch accidentally into two of our EX

Hi Clarke, We pass through BPDUs through VPLS the MX'es- but yes, miscreant users / switches will always be a problem. We do the following to every customer-facing VPLS instance, but only #3 would help you here: 1. Mac Limiting per VPLS Interface (100) (i.e per 'site') 2. Mac Limiting per
