RIP (Routing Information Protocol)
A dynamic route is a path to another network that is “learned”
dynamically. A router that uses RIP broadcasts its entire routing table
every 30 seconds, updating other routers about which routes are
usable. Dynamic routes age and if no updates are received, they
eventually expire.
The SIA2410R unit supports RIP1 and RIP2, RIP1 (version I) does not
support the subnet mask information, whereas RIP2 (version II)
supports CIDR (Classless Inter-domain Route) block address, VLSM
(Variable Length Subnet Masking), route summarization, and security.
RIP is saved as a form of routing table in the internal cache. This
routing information is periodically broadcast to the neighboring routers
by means of the UDP protocol. To update its routing table the host can
receive information that has been broadcast from other routers, and it
can compare its own information with the received information to
generate optimum routing entries. RIP uses a distance vector metric,
so the metric is interpreted as a hop count.
Configuring RIP
Receiving or transmitting for RIP1 or RIP2 updates can be configured
for each interface.
Command
rip enable
<ifname> rxrip1|txrip1|rxrip2|txrip2
Parameters
<ifname>
interface name
rxrip1|txrip1
receives and transmits RIP1 updates
rxrip2|txrip2
receives and transmits RIP2 updates
Usage examples (conf)#
rip enable wan rxrip2 txrip2
