Hi Rick, We have been in a similar situation last year. Originaly we had 7206 VXR NPE-G1's as both access routers and core routers, however maintaining a full bgp table on the core routers became a bit to much for the 7206's and we wanted more interfaces for our access network (and needed to expand the access network).
In the end we went for the 7606/RSP720 as a core router(s) and moved the `core` 7206's to the access network . First of all because our entire network is Cisco which means our support staff wouldn't have to learn a new router OS. Next to that we've tested a M7i which performed flawlessly and I personally like the JunOS config style (tested mpls/ldp/ospf/bgp only, no ip vpn/virtual routers/BBA etc just plain packet forwarding). However we have a policy that every access device needs 2 direct connections to the core routers which means we need quite a few interfaces. Interface pricing on the Junipers is ridicules imho, 18k$ for a single gigabit ethernet connection, for a fraction of that you would get a 24x SFP module for the 7600 series... (add to that that we have a few STM-1 connections which are even more expensive) Kind regards, Erik Rick Ernst schreef: > I'm looking at a network refresh and both Cisco and Juniper are on the > radar.
