Routing protocols

Name IGP or EGP Type VLSM? Updates Algorithm Metric Convergence Port/Protocol
RIP interior (intra-AS) distance vector classful broadcast full routing table periodically Bellman-Ford hop count slow UDP 520
RIP-2 interior (intra-AS) distance vector classless multicast full routing table periodically Bellman-Ford hop count slow UDP 520
IGRP interior (intra-AS) distance vector classful ?broadcast/multicast full routing table periodically constrained bandwidth and cumulative delay (optionally others) slow IP 9
OSPF interior (intra-AS) link state classless LSA. partial updates to topology to known neighbors Dijkstra shortest paths sum of links' cost (cumulative bandwidth) fast IP 89
EIGRP interior (intra-AS) balanced hybrid classless partial updates of topology to neighbors DUAL constrained bandwidth and cumulative delay (optionally others) * 256 very fast IP 88
BGP exterior (inter-AS) classless routes with ASN to peers none. policies TCP 179

5 Striping with parity 3 yes yes

HA cluster
notepad virus yes, it's a virus. just don't run it on Windows.
