separate routing updates sent by the respective routing protocols. Each separate routable
protocol (IP, IPX, and AppleTalk) uses a separate routing protocol. (IP uses RIP, IPX uses RIP,
and AppleTalk uses RTMP.)
multiprotocol routing to exist. In particular, if Router1's E0 interface failed, then IP subnet
10.1.1.0/24, IPX network 1, and AppleTalk Cablerange 1-1 would all be inaccessible. In fact,
the key similarity is that all three Layer 3 protocols use the same concept of grouping devices;
that is, a group consists of all interfaces attached to the same medium. In fact, the following
statement can be made about this similarity:
directly connected IPX and AppleTalk routes associated with that same data link to fail.
