Recommendation for customer monitoring network tool/portal for a large ISP
by Alex Nderitu 27 Oct '11

27 Oct '11

Hello, What solutions do you guys in the fixed network business/ISPs use to provide customer portals for network KPI reporting to customers in a fixed network on real time basis. The KPI in question are network availability, utilization, memory/cpu of managed routers/firewall, jitter, packet loss etc in a multi vendor environment. What would you recommend especially in the licensed/supported options and not the free ones like Zabbix, Cacti, MRTG etc. This solution should scale well for hundreds of thousand of clients. We have been using Orion NPM and it pretty much does the job but would wish to move to something more scalable for SP environment. Regards, Alex.

BGP AS question
by Cliff Bowles 27 Oct '11

27 Oct '11

Greetings. We have a few facilities within a 30 mile radius, and each has an ISP link. We use P2P links at the edge to make certain traffic sourcing from one facility, and destined to the Public IPs at another, stay on the "dirty" links rather than punting out to the ISP. All sites use the same BGP AS. Recently, we were required to turn up an additional facility in a short time frame. It also uses the same BGP AS. However, it does not have a dirty cross-connect link. So, even though this facility has unique /24 public IP blocks, it still has the same AS. One thing we are noticing is that some ISPs don't seem to have a problem allowing this traffic, and some do. I suspect some don't like traffic with the same source and destination BGP AS, even though the prefixes are different at each location. But other ISPs seem to permit this with no problem. My question is: is normal BGP default behavior to permit or to allow this type of traffic? Also, would it be easier to ask the ISP to make an exception, or to buy another AS for the rogue facility? Thanks. Clifford W Bowles, Technical Director Apollo Group | IT Services | Network Engineering 4025 S.

Advice on BGP traffic engineering for classified traffic
by Jack Bates 26 Oct '11

26 Oct '11

I'm curious if anyone has a pointer on traffic manipulation for classified traffic. Basics, I have a really cheap transit connection that some customers are paying reduced rates to only use that connection (and not my other transits). Though I've considered support for cases where NSP peering disputes break out. While I can advertise their networks out the correct transit for return traffic, I still have to figure out how to handle egress traffic. I'm guessing the crux of it is policy routing based on source address, but I'm interested in ways to engineer it to easy management and scalability. I've considered the possibility of an l3vpn to interconnect customers that are not requiring full routes, and possibly some type of vpls tunnel terminated at the necessary router for customers who need full routes. Thoughts, pointers, suggestions? Jack
