8-8 CHAPTER 8: IP UNICAST ROUTING

enable rip splithorizon Enables the split horizon algorithm for RIP. Default setting is

enabled.

enable rip triggerupdate Enables triggered updates. Triggered updates are a

mechanism for immediately notifying a router’s neighbors

when the router adds or deletes routes, or changes the

metric of a route. The default setting is enabled.

config rip add {vlan <name> | all} Configures RIP on an IP interface. If no VLAN is specified,

then all is assumed. When an IP interface is created, per

interface RIP configuration is enabled by default.

config rip delete {vlan <name> | all} Disables RIP on an IP interface. When RIP is disabled on the

interface, the parameters are not reset to their defaults.

config rip garbagetime {<delay>} Configures the RIP garbage time. The default setting is 120

seconds.

config rip routetimeout {<delay>} Configures the route timeout. The default setting is 180

seconds.

config rip rxmode [none | v1only |

v2only | any] {vlan <name> | all} Changes the RIP receive mode for one or more VLANs.

Specify:

■none — Drop all received RIP packets.

■v1only — Accept only RIP version 1 format packets.

■v2only — Accept only RIP version 2 format packets.

■any — Accept both version 1 and version 2 packets.

If no VLAN is specified, the setting is applied to all VLANs.

The default setting is “any”.

config rip txmode [none | v1only |

v1comp | v2only] {vlan <name> | all} Changes the RIP transmission mode for one or more VLANs.

Specify:

■none — Do not transmit any packets on this interface.

■v1only — Transmit RIP version 1 format packets to the

broadcast address.

■v1comp — Transmit version 2 format packets to the

broadcast address.

■v2only — Transmit version 2 format packets to the RIP

multicast address

If no VLAN is specified, the setting is applied to all VLANs.

The default setting is “v2only”.

config rip updatetime {<delay>} Changes the periodic RIP update timer. The default setting

is 30 seconds.

disable rip Disables RIP.

disable rip aggregation Disables the RIP aggregation of subnet information on a

RIP version 2 interface.
