RIP

Name

RIP -- Routing Information Protocol.

Description

Routing Information Protocol (RIP) allows routers to learn about each other's routing, similar to the way that NetRom exchanges nodes broadcasts.

There are various versions of RIP, and XRPi currently implements RIP2RIP98 which was developed by G8BPQ specifically for radio-based routers. If there is a need for other versions of RIP, they may be included in a later version.

RIP98 works by sending its routing table to nominated peers at regular intervals, and accepting routing information from peers. The routes learned by this means are added as temporary entries to the IP routing table. These entries have a finite lifetime, and if not updated regularly they drop out of the routing table.

Configuring XRPi to use RIP98

The following configuration commands are available:

	RIP ACCEPT      Remove a peer from the refuse list.
	RIP ADD         Add a peer to the broadcast list. (*)
	RIP DROP        Remove a peer from the broadcast list.
	RIP LEARN       Allow / disallow route learning. (*)
	RIP REFUSE      Ignore broadcasts from a peer. (*)
	RIP STATUS      Show status of RIP.
	RIP TIMEOUT     Specify lifetime of learned routes. (*)

Commands marked (*) may be used in BOOTCMDS.SYS or IPROUTE.SYS to configure the system automatically.

By default, RIP98 route learning is OFF, so you need to include at least a "RIP LEARN ON" command, to enable your system to learn routes from others. Your neighbours will also need to add your IP address to their RIP broadcast lists.

If you wish to inform your neighbours of your existence and your routing capabilities, you need some RIP ADD commands, one for each neighbour to who you wish to send RIP updates.

If you have LEARN enabled, and there is a neighbour who is sending unwanted RIP updates to you, you may ignore them using RIP REFUSE.

The RIP commands are explained in more detail in section 2 of this manual.
