We are looking to implement a redundant Internet connection with another carrier. &nbsp;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 $$.<br />
<br />
Currently we have a 20MB pipe with Comcast. &nbsp;They have their gear installed at our loction and hands off the Internet connection thru a switch port to our core 6513. &nbsp;We use their IP addresses and have no AS number. &nbsp;<br />
<br />
Is there another way to do this without all that $$? &nbsp;Has anyone out there implemented something similar? &nbsp;Does anyone know if I can get redundant Ethernet hand-off's and what routing protocols have you used?<br />
<br />
Thanks<br />

Redunant Internet connectivity design question

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
