a) receive default routes from the two eBGP peers.
b) no NAt is required on the box
you need an IP services image to run BGP
Advanced IP unicast routing protocols (Open Shortest Path First [OSPF], Interior Gateway Routing Protocol [IGRP], Enhanced IGRP [EIGRP], Border Gateway Protocol Version 4 [BGPv4, IS-ISv4]) are supported for load balancing and constructing scalable LANs. The IP Services image is required.
I am looking at a new router as well. I Have two gateways, one is a 100 meg connection and another 50 meg connection. No BGP just separate providers. I'm an ISP. Would a 2841 with expanded memory work well for this application?
No it would not. Look at the above router performance attachment.
As another poster said you are looking for at least a 7201 with an NPE-G1, better an NPE-G2. This will likely cost you $30k+.
The bare minimum I would use would be a 3845 with max memory, this being ~$12k.
Others have touched it but let me state it plainly -- if you have two providers with >10Mbps links, you will need a router that can move that much traffic while also providing services (it will need some CPU horsepower, which a 28xx does not have a lot of).
You will also want a router that can take two full Internet routing tables so your can choose the best path between the two providers. Each Internet routing table is >200k routes, and this means you will want at least 1GB of memory.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
