hmm; why do you keep questioning people how to run their own networks? step 1. know the limits of your devices step 2. know the limits and purpose of each routing protocols step 3. test test test step 4. does it work for you? if yes: do it, if no: don't it may be entirely approprirate to have a L3 switch run bgp just for internal / small number of prefixes, or for other reasons, depends on the hardware limits and configuration of your topology. getting back to the topic, 2950 switches can create dot1q vlan tags, so can 3500. so can 2900XL but never tried myself.. -J On Sun, Apr 25, 2004 at 10:31:25PM -0700, Alexei Roudnev wrote:

Yes. I've been looking at it and a 7505 with a 3550 behind it seems the way to go for our type of operation.
As a cost cutting alternative - has anyone played with the 2900 XL series using sub interfaces to turn them into virtual router ports ? or vlan groups ? Is it better to just buy a 3550 ?

Yuck. Unless you have very few flows you do not want to use MSFC1/PFC1.
This platform would be good for a file server with few but highspeed flows.
This system costs somewhere around 1300.00 more than a: Cisco 7505 w RSP4 256 Plus (2) VIP 2-50/128 and 3 PA-FE-TX
Obviously the Catalyst is a better unit. But will it be as "burned in" and robust as the venerable 7505 ?
The 7505 will probably handle lots of flows massively better than the SUP1A.
