If you were gonna put down the $$ for a 7206, I would look hard at a little Juniper M5 with a 4-port ethernet card. 40M pps and 5 Gbps ought to be all the throughput you can handle for less than $40K. A 7206VXR's throughput is a fraction of that. Brantley At 07:26 PM 11/1/2000 -0500, Mike Rae wrote:
Are we talking the support of FE interfaces, or support of FE throughputs ?
The switch may indeed support FE ports, but performance of the router will vary with packet size, IOS featues etc. I would be very suspect of the 2621 supporting even 1x10baseT FD at wirespeed ...
Based upon my experience (limited I conceed) the 72xx is the minimum router to support the potential throughput of multiple FE ports ...

You could always use a 2620 or 2621 with their internal 1 or 2 fast ethernet ports and then use an external VLAN savvy switch to get as many more as you need.
Use one switch port for the 802.1q vlan trunk, and set each other switch port to be in a seperate vlan. Create subinterfaces on the router for each, and use the vlan number as the .<whatever> subinterface number for simplicity.
Some reports say a 262x can actually hold 128 meg dram. If not, cisco has again proven they don't learn, or that engineered obsolescence is the arrogant thing to do.
There is the 2650 or 2651 option that DOES support 128 meg, but is sadly overpriced with no expansion to speak of.
If getting the 7206, realise that there is now a dual 10/100 option for the I/O controller card as well as a gig-e/10meg dual port I/O card option. It is less $ than the PA-GE card. The gig-e can do VLANS, too. DON'T get the PA card with dual 100 meg as it isn't designed for full speed.
Also consider the 300 processor as obsolete now with the 400 at the same price. I wonder why the 400 is less $ than the NSE-1, too.

Can anything less than a 7200 handle three (preferably four) fast ethernet interfaces? That was my sole reason for going that route as it seems to be the smallest Cisco that will provide four fast-E connections (according to Cisco docs that I may have misread).
(not sure of cost...)
Well, it's certainly cheaper than a 7206...
