Ciscos, BGP, L2TPV3 pseudowires and loopback IPs
by James Smallacombe 11 Nov '10

11 Nov '10

A simpler question(s) than it sounds: Customer just brought up their first BGP session at a new location. It is up fine with a full routing table, the second provider hookup is a few weeks away. The provider allocated a /24 (x.x.1.0/24) for the network and a /30 for the PTP connection (x.x.129.172/30). For the initial setup, I did not configure a loopback, I just put x.x.129.174 on the WAN interface and set up the neighbor as x.x.129.173. It's working fine. We will need to set up a L2TPV3 tunnel to their old location (single homed, no BGP on that side). Upon initial reading of Cisco docs to do this, we will need a routable IP on a loopback interface for starters. Using one from the /24 LAN is out unless we subnet it, which we don't want to do. So the question is, can I just "move" the PTP IP address x.x.129.174 from the WAN interface to the loopback like this? interface Loopback0 ip address x.x.129.174 255.255.255.252 (that's the mask we're using on the WAN- Cisco's loopback examples show .255) interface WAN1 (actually a gigether) ip unnumbered loopback0 (or no ip addr?) neighbor x.x.128.173 update-source Loopback0 Does this look even close to right? Or do we need another, single routabe IP from the provider for the loopback? Also, I am assuming we don't need separate loopback interfaces for BGP as for the Bridge/Tunnel. What about when the second provider comes up? A second or third loopback to nail up their WAN IP? ***OR*** is there a way to put their WAN I/F IP on the loopback and take it off their LAN Ether...and then do IP unnum loop0 on the LAN?

Gratuitous syn/ack
by Pete Carah 11 Nov '10

11 Nov '10

I'm seeing a significant number (about 1/minute 24 hr/day) of syn/ack packets coming from port 80 of random addresses to random ports on my nameserver and a few other systems. This isn't enough traffic to be really annoying, but is curious. I wonder if the simple explanation (backscatter from syn floods with spoofed source addresses) is more likely, or if there are some probing techniques in "normal" use that use these packets (one could accomplish a traceroute using port 80 packets in either direction...) -- Pete

Extra latency at ATT exchange for UVerse
by Srikanth Sundaresan 11 Nov '10

11 Nov '10

Can anyone explain why ATT's UVerse adds significant delay to packets compared to their ADSL service? For example, pinging 8.8.8.8 from an ADSL gateway shows a latency of ~10ms. From an UVerse gateway, it's about 40ms. Of the extra 30ms, about 10ms can be explained by the fact that UVerse last hop is interleaved. ADSL seems to have Fastpath enabled more often than not (at least in my city). The extra 20ms is more interesting. By pinging each hop obtained by tracerouting to 8.8.8.8, the extra latency seems to be added on the exchange between ATT and Google. It's not just for 8.8.8.8. The same holds for other hosts too. ATT seems to add 20ms when it hands off a (UVerse) packet at an exchange. Thanks, Srikanth
