Appendix A. Comparison of Protocols

This appendix compares some of the well-known protocols that your router

supports. It is provided as a memory aid and is not meant as a reference.

Key to Protocols

Table76 is a key to the protocols.

Table76. Protocol Key
Protocol Description
BGP Border Gateway Protocol.An IP external routing protocol.
FTP,TFTP File Transfer Protocol; TrivialFile Transfer Protocol.
ICMP Internet Control Message Protocol. Used to send network level error
and control messages between routers and hosts.
IP Internet protocol. IP is a widely used standard transport protocol. IP is
the 2210 routers’ basic protocol. IPleaves some error-checking to
higher-level (end-to-end) protocols.
IPX InternetPacket Exchange Protocol.
RIP RoutingInformation Protocol (Routing protocols are used to determine
network topology and data paths). RIP is the most common IP routing
protocol.
SGMP SimpleGateway Monitoring Protocol. Used to obtain statistics in
machine-readable form from 2210 routers.
SNMP SimpleNetwork Management Protocol. Used to obtain statistics in
machine-readable form from 2210 routers.
TCP Transport Control Protocol. An end-to-end (host-to-host) protocol that is
often used with IP.Useful for sending streams of data. Uses checksums,
acknowledgments, and timeouts to ensure the correct delivery and
sequence of data.
