Redunant Internet connectivity design question
Posted on 2009-02-17
We are looking to implement a redundant Internet connection with another carrier. I had implemented a similar scenerio years ago with Internap and Sprint, 2-6509's, our own AS number, and running BGP on the out and EIGRP on the inside. Worked like a champ but this required FlexWan modules with DS3 WICs on both cores and the whole thing was very $$.
Currently we have a 20MB pipe with Comcast. They have their gear installed at our loction and hands off the Internet connection thru a switch port to our core 6513. We use their IP addresses and have no AS number.
Is there another way to do this without all that $$? Has anyone out there implemented something similar? Does anyone know if I can get redundant Ethernet hand-off's and what routing protocols have you used?
