We have two 6509 will active/passive sup 720-3BXL cards in each and 1GB DRAM. Each handles full bgp routing table with 4-5 ISP(eBGP) connections. The problem we are facing is.. 6509 were meant for core/aggregation and seam to be wasted are edge devices. With each ISP added the DRAM creeps up to a point were is it 80% utilized.
I am looking to replace both 6509's with routers which were meant to work on the edge. As mentioned earlier, it will have 4-6 external bgp peers per router. Handle full bgp tables. Should be capable of policy based routing. Any suggestions? I can provide more details if they would help.
Wow. That's huge.
For that kind of WAN bandwidth, you may need to look into an ASR 1004 with ESP 10 or ESP 20. You may also consider an RP2 with it as well.
When you have choosen the ASR, please don't hesitate and have the DRAM loaded up to the eyeballs.
