You have three problems. 1. How do you get 8mbps of traffic into the router. For the 2600 series, it includes.. a. Switched Full-duplex 10baseT Port b. 100BaseT or Faster ethernet Port. c. 8 port T-1 nm with IMA (8 port t-1 atm module) If your providers aren't providing connections via one of the above, you'll have to switch to a different series of routers so you can get the traffic into the router.
2. What routers will support 8 mbps of traffic. 8mbps = 8000000 bytes-sec. 8000000 bytes-sec/1500 bytes-packet = 5333 pps. add a 10% safety margin and you get 6kpps. Look at http://www.cisco.com/warp/public/752/qrg/ The Cisco 2610/11 (The lowest in the 2600 series) is rated for 12-15 kpps. 3. What routers will support full or Partial BGP routes. That depends on how partial they are. If you are accepting only a default route, then it doesn't significantly change your memory requirements. You need an IP Plus image to run BGP, so minimum is 40 mb. I.e. 40Mb of ram is the minimum to run bgp and accept only the default route. If you are planning on accepting the full routing table, then 128mb is the current requirement, but that is continually increasing. 128 Mb is the maximum memory a 26xx will accept, and that's only on the 2650/51 so .... A cisco 2651 with maximum ram would be the minimum choice for full routes, and a Cisco 2621 would be acceptable for partial routes. If your ISP connections are via ethernet, then you're all set with the 2621 or 2651 as they have two FastEthernet ports. Recap: A 2610/11 can take the traffic, and can accept default or partial routes via bgp. If you want to use the 10BaseT ports for the network connections, they need to be connected to a full duplex switch to fit 8mbps of traffic on the line. This is probably not the best unless you are using something other than the 10BaseT port to squeeze the traffic onto the network. A 2620/21 can take the traffic, and can accept default or partial routes via bgp. It is a significantly better choice than the 2610/11 if you are using the FastEthernet ports A 2650/51 can take the traffic, and can accept Full, default, or partial routes via bgp. If you don't require full bgp routes, this isn't a significantly better choice than the 262x. -Ejay ...Cisco Consultant for sale or rent, e-mail off list if you need help. -----Original Message----- From: suaveguru [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 17, 2002 10:03 PM To: [EMAIL PROTECTED] Subject: Least cost router to run BGP (partial or Full) [7:32397] hi all, I am looking at a least cost router that can run full BGP and supports 8mbps of WAN traffic.
