Although 64MB can still cut it with a limited number of peers. CPU is also important. 3640's are very popular, and they work well. Alot of people use the migration to 3660 which has a very fast processor and can take their exisiting 3640 modules. 3620 could also be used, but it has the 64MB limitation. CPU works however. Larger ISP's prefer the 7206vxr, which has an excellent price point, fast processors, and is very service provider centric. 7000's and 7500's are also used where high density is a concern. Usually however, high density is not a function of the borders of most providers.......they will deploy 7200's for the border and the larger chassis like 7000/7500 can be populated with more dense blades. The 7000 is still a very good value. We slam them with serial ports and use them to serve t1 customers (32 t1's per box). An 8 port serial blade is only $500 or so for a 7000. Compare that to a 4 port blade on a 3600 that would run $2000 easy. 7000's can have the RP/(S)SP swapped out with a RSP7000 which essentially turns the 7000 into a 7500 with RSP1. So long as the 7000 can do 64MB (RSP7000 and RP64 can do 64MB) then it can do BGP today and keep up. 2600's fell behind for a while. The cpu couldn't cut it, but it was fine on memory. Now that cisco has the 265x and above out, they are contenders in the BGP game once again. So basically if you have 64MB and a decent cpu, it is a common router for BGP. You can do BGP on a 2501.........don't get me wrong........I am talking about a full table however. 2650 3620/40 7206 those are probably the most popular for customers doing bgp. 7000/7500 and some other more legacy hardware may be found however. brian > > Thanks in advance. > > _________________________________ > FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] > ----------------------------------------------- Brian Feeny, CCNP+ATM, CCDP [EMAIL PROTECTED] Network Administrator ShreveNet Inc.
