Does Juniper Routers mainly used for disctribution level?. I mean is it directly connected to backbone?.
I have not seen Juniper router being used other than as an border router (connected right to your upstream provider). However, I don't have much experience with Juniper router. We are still waiting for our M7i ourselves.
Dave,
I'm aware of the cost involved. But, do you honestly know of how many people actually go and get it relicensed with Juniper directly? It's very very few. Not many people at all.

Yes, The upstream connection is plugged into the Juniper PIC Card as Dave said and then is configured on the router. You then plug in a Core Switch to one of your 100Mpbs/GigE ports and run the core switch to handle all the switchs on your network or several of the core switchs.
The 3550 is great for an edge device and runs OSPF well.
The Summit catches alot of heat for being flow based in a L3 enviorment, but the newer 48si's do ICMP/IGMP in hardware, and Extremeware 7.3, while not true prefixed based routing, uses a IPDA, which will prevent thrashing of the IPFDB and keep up the throughput of the switch under conditions which in the past may have caused high CPU utilization and packet loss.
Alot of people trash extreme, and they have had their dud products, but so has cisco. I had the pleasure of working on a Black Diamond 10k and I was very Impressed. The 6500 has some serious completion from the 10k in the high throughput/high density area.
