[j-nsp] Going Juniper

[Aaron Gould]

I'm literally up working right now in a maintenance window throwing one of
my cable modem cmts communities behind my pair of mx104's... I'm excited to
finally start natting my cable modems...

Previously I have natted all 6,000 of my dsl customers behind this same pair
of mx104's.

I do cgnat via mpls l3vpn's.  it's quite nice as I inject a default route (2
of them) from each mx104, into the cgnat vrf domain, and all my PE's begin
flowing all outbound traffic via the nat boxes.

I understand the MS-MIC-16G cgnat module inside my mx104's can do about 7
million translations and about 7.5 gbps of cgnat throughput.  X2 for both
mx104's in my cgnat arechitecture. (so 15 gbps of nat44 total)

I recall paying about $25k for each MX104 with single RE and one MS-MIC-16G
module, and I think a license that allows for 20 gbps (two 10 gig) ports to
be used.  I simply agg-ether those 2 interfaces and plump them into the P
core and do nat-on-a-stick via 20 gbps of link capacity.

p.s. ftth cgnat will be done via my new mx960's w/MS-MPC-128G's

Greetings,

    I am looking for some advice concerning juniper as an edge router.

    I see there is a terrific amount of used mx104 and mx240 out there and
the specs all seem great. What I'm looking to do is have 2x 10g feeds, route
bgp, do flow exporting, and do a certain amount of ingress filtering to
protect the network from ddos.Id even like to do cgnat for up to 5000 users
but not sure if a single box setup would be wise.

    I just don't have a handle on the various juniper platforms and route
engine options. Love to keep this under $20,000 and get a load of 10g
interfaces. Anyone here can tell me what I should be looking for?

Mike-
