Has someone out there experiences with a real multihomed network (two different ISPs) using cisco 3660 as border routers. Actually we will use two 2 Mbps links (E1), later there might be an upgrade to 34 Mbps (E3).
We want to take the full routing table! Someone told us that we have to use 2 cisco 7204. Nevertheless, cisco 3660 has enough DRAM to take all those routes an it should be able to support two 2 Mbps (34 Mbps) links.
Any objections using cisco 3660 instead of cisco 7204 are welcome.
Full internet routes approx consume 72 MB of DRAM. THE DS3 modules need a minimum DRAM of 64megs for Enterprise feature set IOS, or 48 megs for IP Plus feature set. I would recommend to go for a 3660 with 256 meg. The 3600 has only system DRAM, while the 7000 series have system DRAM as well as Packet DRAM(separate memory to store packets). The Packet DRAM slots depends on the type of NPE used on the 7200. Using two routers, will always be better, because it gives you router redudancy. Cost wise, 3660 would be cheaper compared to a 7200.
Every router, uses, system as well as packet memory. Most routers,share the main DRAM, for the packet/ system memory. The 7200 has separate slots for installing the Packet memory. That means, that they dont share the system DRAM for storing packets. These reside on the NPE of the 7200. I didnt mean to recommend buying 7204 just on the basis of system/packet memory. I was just trying to pitch in some difference between the memory models of the two routers.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
j ai une question j ai achete un routeur cisco 887VA-k9 , je le configuré avec la configuration ci- dessous
