I didn't came across any limitations/scalability issues running PIM to distribute customer m-cast state did any of you please? I'm a fan of the idea to let BGP carry everything, but I fail to see an added value here (maybe PIC-Edge for m-cast?) And yet I'd still have to run PIM at the edge Also

[c-nsp] Rosen mVPN and NG-nVPN together?

2012-06-11 Thread Peter Rathlev
We're currently using Rosen mVPN in a pure C6k/Sup720 network and are happy about it. We might end up in a situation where we need to introduce e.g. Juniper equipment and are wondering if Rosen mVPN and NG-mVPN can coexist. Having the two multicast domains interface with each other via non-MPLS

Hey all, I'm just wondering if the aforementioned switches will listen for NTP requests by default. We have a rigid Change Management policy, and unfortunately I have no spares for these units. I'm trying to come up with the appropriate config so that these units both sync time off the

Keep in mind that SNTP clients don't do the sanity checking that normal NTP does, so an out of sync router could provide bad time to an SNTP client. I've used a time-based ACL in the past so that if the router's clock was before a reasonable time, it would block those packets. I can't remember
