RIP
Issue 5 October 2007 237
Reference IP
Address
The IP address borrowed for an unnumbered interface.
A value of 0.0.0.0 indicates either that the IP address is not valid, or
that the IP interface is borrowing the IP address from a dynamic IP
interface whose IP address is not allocated yet.
If the IP address is not unnumbered this field returns a value of N/A.
State The operational status of the RIP interface - active or inactive.
Status The administrative status of the RIP interface. If checked, the RIP
interface status is enabled. If unchecked, it is disabled.
RIP Version The router can be configured to operate either RIP version 1 or RIP
version 2 on each IP interface. The configuration of the RIP version
must be consistent on each subnet. That is, all routers should be
configured with the same RIP version on their interface to the subnet.
When possible, homogeneous configuration of the RIP version in the
network is recommended.
● Rip1 - The router runs regular RIP on that interface, following
the RIP version 1 subnet aggregation rules. That is, it advertises
an aggregate route for the net as opposed to advertising subnet
routes across the network boundary.
● Rip2 - The router runs RIP version 2 on that interface. RIP
version 2 advertisements are sent as multicast rather than
broadcast. No route aggregation is done in RIP version 2. RIP
version 2 allows for Variable Length Subnets Masks (VLSM),
meaning that subnets of the same net may have masks of
different lengths, and may be of different sizes.
Send Receive Mode What the device sends on this interface. Values are:
● Talk-listen - RIP updates contain the entire routing table.
● Talkdefault-listen - RIP updates contain only a single entry.
This advertises the router as the default router.
● Listen-only - No RIP updates are sent.
Cost The cost of using this interface. RIP chooses the route with the lowest
total cost (metric) for each destination.
Default Route
Metric
The metric of the default route entry in RIP updates originated on this
interface, if configured to SendDefaultOnly.
Default Route Mode If talk-listen, accepts default route entries in RIP messages received
from other routes on this interface. If talk-only, does not accept default
route entries in RIP messages received from other routes on this
interface.
