A bunch of different concepts are getting mixed up in this discussion.
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.
