[j-nsp] Juniper box equivalent to GSR

[Dusan Avbreht]

M-320 can be used as edge and core IP/MPLS routers. Cisco XR12k and way more
CRS-1 are core routers lacking edge feauters.
i.e XR12k and CRS-1 they don't have VPLS support.

Differences:

M-320                               XR12k        	CRS-1

VPLS BGP style                      no               no
L3/VPN                              yes              no
Graceful restart for L3VPN          no               no
L2VPN BGP style                     no               no
L2VPN LDP                           yes              no
BGP flow spec                       no               no
MPLS Pt-to-multipoint LSP           no               no
vrrp-passive learning               no               no

We're planning on getting a new Core (P) router, we had a BPX-MGX(cisco)
network, which ran Cell mode MPLS, we need to migrate to Frame-mode

The BPX was used as shelf feeder from MGX ATM switches which had a router
acting as PE, now we'll continue using the BPX as aggregator PEs trunks(pure
ATM switch),

So we initially looked at GSR 12410, in my humble opinion, it has decent
port density compared to price (around 250K US$) when compared to Juniper
boxes with similar ports density,

We talked with Juniper folks, they were showing us M40 which was quite
expensive, still not the same port density, which router in Juniper would be
equivalent disregarding prices, due to price limitations we were trying to
do it with M7i, processing wise, it'll do it, but with no room for growth,
add to that the Multicast module that should be added if you decide to add
Multicast.

Our GSR as P will only run IGP and MPLS transport, it'll initially have 3
GigaE ports with NPE-G1, 4 ATM OC3 ports and a bunch of PoS for new PEs
we'll add later

Has anyone had this experience before, people recommend Engine 3 cards and
were pointing that IOS is one huge advantages/features to go over Juniper,
please, i welcome your opinions on both GSR and equivalent Juniper boxes.

Any known problems with GSR or Juniper ?

Thanks
