Description
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.
The cost of using this interface. RIP chooses the
route with the lowest total cost (metric) for each
destination.
The metric of the default route entry in RIP updates
originated on this interface, if configured to
"Default Route Only".
Whether to accept default route entries in RIP
messages received from other routes on this
interface.
The method for handling routes learned from this
interface, when sending updates to this interface.
Possible methods are:
• Poisoned Reverse - The routes are advertised
to this interface as unreachable.
• Split Horizon - The routes are not advertised
to this interface at all.
• None - The routes are advertised to this
interface as is.
Authentication Method. Possible methods are:
• None
• Simple
