Morning! I have an OT question... I have two 40mbps internet connections from the same ISP today, each one runs into a 2921 router. I receive a default route via eBGP with ISP and the two routers peer via iBGP with each other. I'm going to be dropping one internet connection soon and picking up a second ISP, same bandwidth. We're just doing this to diversify. Question is: Would the 2921s have enough resources to accept full internet tables from each ISP? The way I look at it, each router would store the BGP table from the ISP, and also store the table from its iBGP peer... with soft-reconfiguration enabled, It then stores a second copy of each peer's updates. Basically requiring the router to store the entire internet BGP table 4 times... Am I looking at this correctly?
I know my current ISP has an option for them to advertise their originated routes (core routes) and a default, so that would significantly decrease the update size from that peer, but I don't know if my incoming ISP has that option. Routers are default hardware spec, 1g RAM, 256mb Flash IOS 15.2(4)M3 Thoughts?? _______________________________________________ Free CCIE R&S, Collaboration, Data Center, Wireless & Security Videos :: iPexpert on YouTube: www.youtube.com/ipexpertinc
