Thread Index RE: [isp-bgp] Cisco 3560 question
Hmm . . . I question if that is correct (the 1GB DRAM part of your statement). I have two 2811s each receiving full routes from a different Tier-1 ISP across a T-1, and of course an iBGP session between them. I was originally running only one router with full Internet routes from only one carrier with 256M, no problem. When I added the second router and second BGP peer also with full routes, the routers couldn't maintain the sessions -- kept resetting due to memory insufficiency. So I upgraded both routers to 512M and no problems. I suspect I could probably run in this configuration with 320M or 384M, but I just figured why screw around and upgraded to 512M. With that said, I doubt the 2851 has much if any more overhead at idle than the 2811, and could probably get by on 384M-512M. Below is output from one of my 2811s Note: I am running NTP server, DHCP (very little overhead), OSPF (very little mem overhead), HSRP, ACLs on these routers. No CBAC or QoS.
