Your Action
Configure the number of seconds that RIP waits before updating the
routing table. Use this option to prevent route flapping when handling
high metric routes. By default, RIP waits 120 seconds between routing
table updates. When configuring this option:
Ensure that the value is at least three times the value of the Update
Timer.
Ensure that the value does not exceed the sum of the Update Timer
value plus the Flush Timer value.
For example, if the Update Timer is 60 and the Flush Timer is 180,
you can set the hold down time value between 181 and 239.
Configure the number of seconds that elapse before RIP resends the
RIP routing table to a demand circuit neighbor that did not respond.
You can also configure the number of times RIP attempts to
retransmit the routing table. By default, RIP resends every 5 seconds.
Configure the number of seconds between demand circuit checks.
By default, RIP sends a request through the demand circuit every
three minutes to verify that the tunnel interface is up. You can also
configure the number of times a demand circuit must fail to respond
before RIP considers the circuit down. By default, RIP never considers
an unresponsive circuit down (Number of Retries is 0).
Configure the following timers:
Update Timer—Configure the number of seconds that the virtual
router sends RIP route database updates to neighbors.
Invalid Timer—Configure the number of seconds after a neighbor
stops advertising a route that RIP considers the route invalid. By
default, RIP considers a route invalid 180 seconds after a neighbor
stops advertising it.
Flush Timer—Configure the number of seconds an invalid route
remains in the RIP route database. By default, RIP removes a route
that has been invalid for 120 seconds.
Configure the maximum number of packets that the VR can receive
per RIP update.
Configure the maximum number of RIP neighbors allowed on a single
interface. By default, RIP allows up to 16 neighbors for the same
interface.
Configure the access list that defines trusted RIP neighbors. If you do
not select an access list, RIP uses multicasting or broadcasting to
detect neighbors on a RIP-enabled interface.
To control which routes RIP learns and advertises, configure the
following:
The inbound route map defines the routes that RIP learns.
The outbound route map defined the routes that RIP advertises.
