Configuring IP Routing
This chapter contains the following topics:
Introduction to IP routing on the Pipeline
An IP router moves data towards its destination using the most efficient path it
knows. IP routers keep track of the source and destination addresses of packets it
handles, builds tables with this information, collects information in routing tables
of other routers, and can advertise its own routes. (For information about routing
packets using the Internet Packet eXchange protocol used in NetWare LANs, see
Chapter 4, “Configuring IPX Routing.”)
The most common uses for IP routing connections in the Pipeline are to:
• Enable IP connections to the Internet (through Internet Service Providers).
• Connect distributed IP subnets to a corporate backbone (telecommuting and
remote office hubs).
The Pipeline supports IP routing over PPP, MP, MP+, and Frame Relay
connections. The Pipeline is fully interoperable with non-Ascend products that
conform to the TCP/IP protocol suite and associated RFCs.
