RIP
How RIP Operates on the Device
Cisco 500 Series Stackable Managed Switch Administration Guide
This results in the following behavior:
- If the metric value of a static route is equal to or less than 15, this value is
used in the RIP protocol when advertising this static route.
- If the metric value of a static route is greater than 15, the static route is
not advertised to other routers using RIP.
The static route configuration 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 and on IP interfaces connected to
router rA (router rB). In contrast, routers rB and rC derive and distribute their routing
entries using RIP.
The static route configuration of router rB, can be propagated to router rC using
either the default metric or transparent system. A static route is redistributed
either with the static route's metric (transparent metric) or with the metric defined
by the default-metric command.
