Using CE Router for Internet and VPN services

Hi, can someone explain me why service providers (Internet and/or L3 VPN services) obligate customers to use CE routers. Why they cannot configure more than /30 (in some cases /31) subnet mask on PE interface side for me? In that case I can use cheap L2 switch and use default gateway on all my

Please describe all benefits and detriments of using more than /30 subnet on SP PE. Some good links will be very useful for me. Don't know all, but have you see the arp tables on a PE router? Have you seen some of the crazy things devices other than routers can do on ethernet? Good

Re: Border routers

Thank you guys, This will be useful, but I still have some questions: Where can I see comparations between the routers? Also, where can I find datasheets containing FIB, RIB and BGP routes limits for cisco and Juniper? It is quite dificult! Thanks again! 2009/7/17 Larry Stites

Visio diag automations

Hi All: I have to create Visio diagrams for sales engagements for a webhosting provider. I use the same template based on our standard architecture but vary the number/model/detail of the servers. I am sick of the cut-n-paste approach and am wondering who has automated some of these processes.

Cisco 7600 (7609) as a core BGP router.

I have an opportuniy to put two 7609s into the core of my network. Currently we have 3 upstream providers, taking full BGP routes. (2 in one router and one in another). We have 17 BGP peers/customers (peering to each router), and adding about one new BGP peer every 2-3 months. It is a modest

Re: Cisco 7600 (7609) as a core BGP router.

We use the 7600 platform as a Customer Border device. It attaches directly to our core, and directly to our customers. This has been a solid platform. Before this we used to use the 7600 as a load balancer for a DNS cluster. Worked fairly well. We use the 6500 series for our main network
