I'm looking into network monitoring utilities for both gathering basic statistics conducive to my enterprise as well as looking for anomalies in traffic traffic. I'm curious as to how NANOG approaches this problem. Are most of your statistics gathered via netflow, or sFlow? How do you gather them, and process them? What do most of you use the data for? Deciding (de)peering agreements? Reducing latency to your biggest customers? How 'standard' are the industry standards (Fluke, Arbour). I've experimented with pm-acct, and flow-tools. How do you leverage flow-tools and pmacct? -- Sargun Dhillon deCarta VoIP (US): +1-925-235-1105

"we'll fix our ipv6 support by, well, > not using it!" It's not Microsoft's IPv6 support they're fixing, which works fine from my experience with it, they're making sure you can access sites if your ISP or Router's IPv6 handling is screwed up. --------------------------------------------------- No, they're just going to force Micr0$loth machines prefer IPv4 on World IPv6 day, rather than the normal prefer IPv6: "The following Fix it solution will resolve the issue by configuring your computer to prefer IPv4, instead of IPv6. By default, Windows prefers IPv6 over IPv4." Kinda makes IPv6 day semi-moot doesn't it... scott

7206 NPE-G2 with 4 full table feeds
by Eric Morin 01 Jun '11

01 Jun '11

Hi I have an application where I have a 7206 with NPE-G2 (1G RAM) that currently has a full table from an eBGP peer and a full table from a co-located IBGP peer. I want to mesh this guy to two other IBGP peers that will also send their full tables. There is roughly 400Mbps (adding both direction) with an OSPF process (<30 routes) and an ISIS process (<20 routes). I haven't been very successful at finding real life BGP scaling for this platform and was hoping that someone out there may be doing something similar (4 x full table feeds with ~400Mbps) and can provide feedback on performance and/or stability. I have soft reconfig inbound enabled on the current two feeds, I assume that this will make a difference in this application with regards to available memory for all 4 feeds? Thanks in advance Eric
