Here's a quick note to clear the air. A routing protocol learns the path(s) to remote networks. Examples are OSPF, RIP, EIGRP, BGP, RTMP, AURP, Novell RIP and NLSP, etc. EIGRP is a routing protocol that can handle routing for IP, AppleTalk, and IPX. That makes it unique. It has a routing engine that can be used by each of these protocol suites, as well as separate mechanisms to deal with unique issues for each suite. This multiprotocol feature of EIGRP has nothing to do with redistribution. Redistribution is the process whereby a routing protocol can learn routes from some other routing protocol. For example, you can redistribute RIP routes into OSPF. I don't know if this is what the responder had in mind, but by default, the Cisco IOS software redistributes AppleTalk RTMP routes into AppleTalk EIGRP, and vice versa. By default, the Cisco IOS software redistributes IPX RIP routes into EIGRP, and vice versa. These are nice features for companies that still run RTMP and IPX RIP on their LANs but have migrated to the more efficient EIGRP on WANs. Cisco made up the silly term "routed protocol," and they use it somewhat inconsistently. But in general, it means the network-layer protocol that carries the payload that gets routed through the network. Examples include IP, DDP, IPX, etc. A router has two jobs: 1) Participating in a routing protocol to learn paths 2) Forwarding routed traffic (This is sometimes called switching, just to confuse matters) OK, that's enough for now.

RE: Routing Protocol Load-Sharing
Chuck, Thanks for the input. I agree with your logic. But part of the problem is that these are International circuits going from one country to another. And believe it or not, most of the time it's much cheaper to bundle several E1s or T1s together instead of getting a fractional T3 or E3 internationally (I know, I work for WorldCom). - Evan -Original Message- From: Chuck Larrieu [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 26, 2000 11:02 AM To: Cisco Mail List; Evan You Subject:RE: Routing Protocol Load-Sharing Evan, at some point you might want to look beyond single circuits. An alternative might be to aggregate your bandwidth by having your carrier terminate it as ATM, and populate your routers with IMA cards to give you bandwidth. Fractional DS3 should be a lot less expensive and gives you a lot more room to grow. As you have now discovered, adding T-1s to solve bandwidth problems has its limits. The fact that you have 12 point to points between two sites tells me 1) that it's past time to look at this with fresh eyes, 2) your company must have too much money, and 3) your telco really loves you :- OSPF is 4 equal cost paths. EIRP is 6, and the paths can be of unequal cost. Where are you located? Contact me off line.

Some routing protocols run right on top of IP, some on top of UDP, some on top of TCP, and IS-IS runs directly over the data-link layer, so researching the answer is a bit difficult. Your best bet is to go to the RFC for the protocol of interest or RFC 1700, the Assigned Numbers RFC, as Chuck L. said.
