Enabling Rip On Dynamic Ip Interfaces; Clearing Dynamic Rip Interfaces - Juniper IGP - CONFIGURATION GUIDE V11.1.X Configuration Manual

Enabling RIP on Dynamic IP Interfaces

You can use the ip rip copy-to-dynamic command to enable RIP on dynamic,
unnumbered IP interfaces. This command allows the dynamic interfaces, as they
are created, to copy RIP settings from a numbered IP interface to which the interfaces
refer for their source address.
CAUTION: RIP transmits a complete set of routing updates at each update interval.
This can result in a very large number of RIP updates. When configuring RIP over
dynamic interfaces, we strongly recommend that you configure an output policy on
the reference interface to limit the amount of routing information that RIP transmits
to each peer.
ip rip copy-to-dynamic
CAUTION: Issuing the ip rip copy-to-dynamic command enables RIP on all dynamic
unnumbered interfaces that reference the interface and become active after issuing
the command. This may unintentionally include dynamic interfaces created on MPLS
tunnels or subscriber interfaces where you would not want to enable RIP. To avoid
this possible misconfiguration, take care to reference dynamic interfaces where RIP
is not required to another numbered interface on which RIP is not enabled.

Clearing Dynamic RIP Interfaces

You can use the clear ip rip dynamic-interfaces to clear any existing dynamic RIP
interfaces that were created by the ip rip copy-to-dynamic command. If the router
Use to enable RIP on dynamic, unnumbered IP interfaces. This command allows
the dynamic interfaces to copy RIP settings from the numbered IP interface to
which the interfaces refer for their source address.
Once created, the dynamic RIP interfaces do not track configuration changes on
the numbered interface from which they originally inherited the configuration.
To reinherit RIP settings, use the clear ip rip dynamic-interfaces command.
Example
host1(config-if)#ip rip copy-to-dynamic
Use the no version to stop the use of RIP configuration on any new, dynamic,
unnumbered IP interfaces. The no version does not remove all existing, active
RIP interfaces that were created after issuing this command. To remove all
existing, active RIP interfaces, use the no rip copy-to-dynamic command to
stop the use of RIP on any new, dynamic interfaces, and then use the clear ip
rip dynamic-interfaces command to clear any existing RIP dynamic interfaces.
