My dear Friends,
Please justify and help clearing doubt:
Why are RIP and BGP, Application Layer Protocols and IS-IS, OSPF, IGRP and EIGRP are non Application Layer/Network layer protocol?
My understanding:
RIP (UDP/520) is a Distance Vector routing protocol and RIP routers exchange complete routing table, BGP (TCP/179) is Path Vector protocol and also exchanges complete Routing Table.
However,
OSPF and EIGRP are network layer protocols, EIGRP has its own transport protocol (RTP) but both these protocols exchange only link state information and prepare their own indigeneous routing table.
Is it because:
RIP and BGP have to exchange the routing table and OSPF, EIGRP need not?
EIGRP has its own transport layer protocol?
Thanks,
