Thanks to everyone who responded. Looks like I'm going to have to invest in a PA-MC-2T3+ card for the 7206...I have at least four PA-MC-T3 cards, and they're not going to work the way I want them to (unless I rate-limit them).

This is for point-to-point DS3, right? I don't think you want -MC- anything, you'd want e.g. PA-2T3+ . (I don't remember the original message though.) mm

Thanks. I not very familiar with the integrated DSU T3/E3 command set - still used to the good ol HSSI ports. I'll agree, this sounds like a better solution if you are using one of the integrated cards. Yes - you are correct, in my solution both sides should always use a traffic-shape or other shaping QoS command. The rate limit is a final "police" in case the customer does try to send more than you would like them to. Again, agreed, obviously if you can control the port speed (above - DSU bandwidth), that's a better solution. -- Daniel Ellis, CTO, PenTeleData (610)826-9293 "The only way to predict the future is to invent it." --Alan Kay -----Original Message----- From: Michel Py [mailto:michel@arneill-py.sacramento.ca.us] Sent: Friday, December 19, 2003 10:58 AM To: Bryan Heitman; nanog(a)merit.edu Subject: RE: Bandwidth Control Question > Bryan Heitman > Why not simply use configuration option Cisco gives > you to set your DS3 to 6 meg dsu bandwidth X That's what I do, works fine. > Dan, your suggestion will unncessarily tax his equipment. Not only that, but the rate-limiting on the input interface will likely force the customer to do some QOS at their end too; the discrepancy between what the customer's router thinks the bandwidth is and what it really is will cause packet loss. I like the solution of the sending interface to queue the egress traffic at whatever speed is available better. Michel.

Tom, My suggestion is to enable the full DS3 and have each router traffic-shape to 6M on the neighboring interfaces. Rate-limit on the input of your router to disallow the customer from sending you more than the limit. Remember that for the most part rate-limiting polices, where traffic shaping performs more buffering and shaping. That's why you should use the combo of a shape on the sender side and a police on your side to protect. --Dan -- Daniel Ellis, CTO, PenTeleData (610)826-9293 "The only way to predict the future is to invent it." --Alan Kay -----Original Message----- From: Claydon, Tom [mailto:Tom.Claydon@DobsonTelco.net] Sent: Friday, December 19, 2003 10:26 AM To: 'nanog(a)merit.edu' Subject: Bandwidth Control Question Hello, A customer of ours in the next building would like 6M of Internet bandwidth from us, so we would wire a DS3 between the two buildings for connectivity.

Hello, Can anyone confirm claims from Cogent that there is an MFN fiber issue between PHL and DCA that creates 10-15% packet loss? Simple test are pointing at the Cogtent not having enough capacity between PHL and DCA. According to Cogent that issue had been happening for several days now. Alex

I'm seeing the following in RouteViews (possibly since they started getting data from paix): route-views.oregon-ix.net>sh ip bgp 0.0.0.1 BGP routing table entry for 0.0.0.0/, version 19579757 Paths: (2 available, best #2, table Default-IP-Routing-Table) Not advertised to any peer 6939 6461 216.218.252.152 from 216.218.252.152 (216.2t8.252.152) Origin IGP, localpref 100, valid, external 6939 6461 216.218.252.145 from 216.218.252.145 (216.218.252.145) Origin IGP, localpref 100, valid, external, best Is this routeviews own set default or some other default route improperly appearing in there (weren't routeviews filters supposed to filter out this kind of all-net advertisements)? P.S. And am I correct in assuming this 0.0.0.0/0 and not 0.0.0.0/8 route? -- William Leibzon Elan Networks william(a)elan.net
