6.7. Using RIP Dynamic Routing on Debian

Problem

Your networks aren't all that complex, but you don't want to hassle with manually configuring routes. Isn't this the kind of work that computers should be doing, the repetitive boring stuff? Your routers are Debian-based.

Solution

Indeed, this is the sort of drudgery that computers excel at handling. There are two categories of dynamic routing protocols: interior and exterior. In this recipe, we shall look at Routing Information Protocol, the simplest interior routing protocol. RIP is included in the Quagga suite of routing protocols.

Installation is boringly easy:

	# aptitude install quagga

Now, you must edit some configuration files. Start with /etc/quagga/daemons, and enable zebra and ripd:

	##/etc/quagga/daemons
	zebra=yes
	bgpd=no
	ospfd=no
	ospf6d=no
	ripd=yes
	ripngd=no
	isisd=no

Next, create /etc/quagga/zebra.conf:

	!/etc/quagga/zebra.conf
	hostname router1
	password bigsecret
	enable password bigsecret
	service advanced-vty
	log file /var/log/quagga/zebra.log
	!
	!administrative access controls- local machine only
	!
	access-list localhost permit 127.0.0.1/32
	access-list localhost deny any
	!
	line vty
	  access-class localhost

Now, create /etc/quagga/ripd.conf:

 !/etc/quagga/ripd.conf hostname router1 password moresecret enable password moresecret router rip network eth1 redistribute static redistribute connected service advanced-vty log file /var/log/quagga/ripd.log ! !administrative access controls- local machine only ! access-list localhost permit 127.0.0.1/32 ...
