Routing Information Protocol (RIP) is a distance vector protocol used in moderate-sized
autonomous systems (AS). Security devices support RIPv1 and RIPv2 (as defined by RFC
2453) and additional MD5 authentication extensions (as defined by RFC 2082).
Use RIP for dynamic routing on moderate-sized networks and to manage route information
within a small, homogeneous, network such as a corporate LAN. The longest path allowed
in a RIP network is 15 hops; a metric value of 16 indicates an invalid or unreachable
destination. RIP supports both point-to-point networks (used with VPNs) and broadcast
or multicast Ethernet networks. RIP does not support point-to-multipoint interfaces.
RIP maintains its own database of routes, including RIP protocol routes and redistributed
routes. This database contains one entry for every destination that is reachable through
the RIP routing instance. RIP adds the best routes to the VR routing table based on the
virtual router's ECMP limit (configured in the General Properties area of the virtual router)
and the alternate route limit (configured in the virtual router's RIP parameters). RIP sends
out messages that contain the complete routing table to every neighboring router every
30 seconds. These messages are normally sent as multicasts to address 224.0.0.9 from
the RIP port.
To enable RIP on a security device, you must first enable RIP on a virtual router, then
enable RIP on individual interfaces. You can also configure optional RIP settings, such
as the following:
Global settings, such as timers and trusted RIP neighbors, that are set at the VR level
for the RIP protocol.
