OUTING
IPX RIP Mode
You can exchange routing information on a NetWare network using the
ipx rip mode
option. This option selects the IPX RIP mode that is
appropriate for your network and selects the routers that use RIP mode to
create and maintain their dynamic routing tables.
In IPX RIP mode, one router exchanges routing information with a
neighboring router. When a router discovers any changes in the network
layout, it broadcasts this information to any neighboring routers. IPX
routers also send periodic RIP broadcast packets that contain all routing
information. These broadcasts synchronize all routers on the network and
age those networks that might become inaccessible if a router is
disconnected abnormally from the network.
Important
Considerations
Consider the following guidelines before you use the
ipx rip mode
option:
■
The system has three RIP modes:
■
Off — The system processes no incoming RIP packets and
generates no RIP packets of its own.
■
Passive — The system processes all incoming RIP packets and
responds to RIP requests, but it does not broadcast periodic or
triggered RIP updates.
■
Active — The system processes all incoming RIP packets, responds
to explicit requests for routing information, and broadcasts
periodic and triggered RIP updates.
■
The system has two RIP triggered modes:
■
disabled — Broadcasts IPX routes 3 seconds after learning them.
■
enabled — Broadcasts IPX routes immediately after learning them.
