We recently added an additonal T1 to our 2621 router. Both T1's are point-to-point to the same ISP. How do you config these two T1 interfaces to aggregate or load-balance our outbound internet traffic? Thanks in advance for any help
Here the routers will treat the two T1's as a single 3mbps pipe by splitting up the traffic packet by packet at Layer 2 (PPP).
You can also do equal cost IP load balancing by configuring two default routes on your router that point to the each of the ISP's routers. Here you should ask the ISP to use equal cost load balancing to your assigned address space so you can get inbound
traffic to load balance ... as this is the majority of traffic in a typical environment.
The notion that you really need a pumped-up router to run BGP is mostly overblown. Yes it is often advisable to have a good router to do your BGP, but it's not as necessary as a lot of people think. I've run BGP just fine on a 2500 with 8 MB RAM. The key is not to accept the entire BGP Internet route table and not to have lots of BGP peers, but regular enterprise networks have little reason to do either.
And even if you insist on accepting the entire BGP route table, it doesn't require THAT much memory. For example, 100,000 routes consumes only 71 MB of RAM, and 30,000 routes consumes less than 30 MB. BGP is resource-intensive, but not as resource-intensive as it is often made out to be.
