IP Configuration: RIPv2
How Rip Operates on the Device
Cisco 500 Series Stackable Managed Switch Administration Guide
Using RIP in Network with Non-Rip Devices
Static route configuration and connected interfaces must be taken into account
when using RIP. This is shown in the following, which illustrates a network where
some routers support RIP and others do not.
A Network with RIP and non-RIP Routers
Router rA does not support RIP. Therefore, routing entries with an appropriate
metric are configured statically on this router. While on router rB the route to router
rA is considered a connected route. In contrast, routers rB and rC derive and
distribute their routing entries using RIP.
The connected route configuration of router rB, can be propagated to router rC
using either the default metric or transparent system. A static/connected route is
redistributed either with the route's metric (transparent metric) or with the metric
defined by the default-metric command.
See Redistribution Feature
RIP Authentication
You can disable authentication of RIP messages per IP interface or enable one of
the following types of authentication:
• Plain text or password—Uses a key password (string) that is sent along
with the route to another router. The receiving router compares this key to
its own configured key. If they are the same, it accepts the route.
