[WBEL-users] Layer 3 Routing

Alon,

I think what they meant by layer 3, is the actual routing protocols as 
in OSPF(open shortest path first), RIPv1/v2 (routing information 
protocol) or whatever else, considering this NOC probably uses cisco or 
some other "routers".  In which case there are daemons like routed and 
zebra you may want to check out.  There are premade linux routers with 
such protocol support built in.  check out:

http://www.coyotelinux.com/   --Ive heard and seen great things done 
with this.

Google'ing for linux routers should put you on the right track.
