[c-nsp] Router or Layer3 Switch

Arie thanks for the information.  I have another thing before I make a
decision.  I have my network setup as follows:


7206VXR
Int f0/0 has several (50 or so) /28 subnets 

F0/0 <--------> 2950 port 1


Now if I had a L3 Switch (in place of the 2950) can an interface on an L3
switch have multiple subnets?  If I put a router in place of the 2950 switch
I could easily define multiple subnets per Interface like I do on my edge
router. I am just trying to look for the best way to do this since I have
never dealt with any L3 switches.

K,

If you need L3 with many Ethernet ports a L3 switch would be just what
you need.
Be aware that these switches use hardware resources for L3 forwarding,
so you may need to choose the right model. This is especially relevant
if you plan for example to run a full internet BGP table (look at
7600/6500 at this case...)

Take a look at this kind of L3 switch. I think it is the right entry
point for what you may need:

We run a fairly large Wireless Internet service.  Right now my network
is all switched/bridged and is time to route this network.  I have 8
Radios at my main location that are connected to the segments of our
network.
Currently all these 8 Radios Ethernet ports plug into a 2950 switch with
1 port on the switch going to my router.  I currently have NO Vlans,
just switching only.  I would like to segment the broadcast domains by
using a router or possibly a layer3 switch.  I am running DHCP on this
network and that is the only service that I am running.  I have limited
experience with
Layer3 switches, so would this be a good fit for one since I need so
many Ethernet ports?  Can a layer3 switch run routing protocols like
OSPF, EIGRP, BPG if in the future we decided to deploy these on our
network?
