[c-nsp] BGP Filtering Policy with regular expressions

Hello all I am trying to write a BGP policy using regular expressions for outgoing filtering. I need to allow customer AS numbers to be announced by our network as well as any prepends they send or any AS behind our customer's AS. e.g allow 12345 678 9123 12345 12345 etc I did try

Re: [c-nsp] BGP Filtering Policy with regular expressions

Your regex should accomplish what you want... as long as you are prefix filtering your peers incoming and/or filtering your outgoing prefix announcements then you should be ok... if you are not then you are leaving yourself open to the possibility of a peer accidentally or intentionally announcing

Re: [c-nsp] BGP Filtering Policy with regular expressions

The solution to what you are describing is really using community strings to tag routes coming from customers then filtering announcements based on those tags. Google is your friend here. If not, hit me off-list for some cisco config examples. John van Oppen Spectrum Networks LLC

[c-nsp] Rate-limiting traffic on 3500

Hello, I am trying to figure out a way to set up some traffic limiters. Specific situation is: I have several VLANs in a 802.1q trunk on one port. I need to control the _outbound_ traffic rate with a different CIR for each VLAN. Traffic-shaping would be nice, but I don't think it's supported.

Re: [c-nsp] PBR and BGP Question

How are you getting the default route into your core? If your ISP border routers, and core are running iBGP, simply use the local preference variable in BGP to send out the prefered ISP. If that ISP connection goes down, the next highest local pref will become the default. Depending on the

Hello, I've got a cisco 3560 (WS-C3560G-48TS-S) pulling in (80Mbs, 6500pps) on one switch port, and sending it out a trunk... cpu load is 5%. Another cisco 3560, pulling in that same traffic on a trunk and sending it out a layer3 point-to-point gigE is running at 70 to 80% (cpu hog is IP Input).

Re: [c-nsp] PBR and BGP Question

We are sending the default routes via eigrp. BGP only runs on the border routers so using the BGP method probably won't work. I was looking at filtering out a subset of customer outgoing traffic and sending it over a cheaper bandwidth provider but I did not want to send all traffic out one or
