[c-nsp] RSVP QoS, CAC and HQF

Hello, I'm working on setting up RSVP Call Admission Control for Cisco's call manager. I have the CAC working nicely, but my problem is with ensuring that the reserved bandwidth will actually get queuing reservation in the data plane. So my question is not voice specific but rather RSVP with Dif

[c-nsp] WRED thresholds and queue-limit

Hello, Is this a valid configuration of WRED, where the queue-limit is set to 64 packets (default), the WRED Min Threshold is 100 (packets) and Max threshold is 400 (packets)? Would this configuration defeat the whole purpose of using WRED, as the average queue depth will never reach 100 packets (m

Re: [c-nsp] MPLS/BGP - want to add backup IPSEC VPN

Peter If you are the customer and have multiple sites, then I would suggest you look at Dynamic Multipoint VPN (DMVPN). With DMVPN you can have each branch site create a tunnel dynamically when it needs to send traffic to the other sites in case of the MPLS link failure. DMVPN only works on routrs,

I would defiantly check out http://onesc.net/communities/ it lists communities of major providers. You can see if your ISP_2 is on there and supports modifying the LOCAL_PREF with communities. That happened to me before where one ISP was setting a higher preference for a path with longer AS. To

Re: [c-nsp] Detect Upstream ISP's BGP problems.

That sounds like a good idea. Thank you very much. What do you think of using conditional advertisement based on their Route Reflector to advertise a default route? (I think the biggest problem is that most ISPs might not want to do that correct?) Thank you again. Tom -Original Message--

So what would be the behavior if I set the community for Cogent to set the Local Preference to 50 in terms of transit traffic?

Re: [c-nsp] BGP Multihomed Selective/Conditional Advertisement

So what you are saying is that if I use communities to have Cogent prepend the pefix few times, Cogent's routers will ignore the multiple ASN in the path, but when they export it to their peers that path should be longer than the path through ATT because of Cogent's extra ASN in there, correct?
