RIP

Layer 3 Management > RIP > RIP VRF Creation

• VRF Name—default is available for a VRF context name for which RIP has to be enabled or disabled. VRF allows multiple instances of a routing table to co-exist within the same router at the same time.
• VRF Status—select the VRF status in the router. The default option is Disabled. The list contains:
  • Disabled—disables RIP on the VRF instance.
  • Enabled—enables RIP on the VRF instance to allow multiple instances of a routing table

• Add—adds and saves new configuration.
• Delete—deletes the selected entry.

Layer 3 Management > RIP > Basic Settings

• Select—click to select the Context ID for which the RIP configuration is modified.
• Context ID—default.
• Context Name—displays the Context name for the VRF instance. This value represents unique name of the VRF instance and is a string of maximum sizeof 32.
• Security—select the security level of RIP to accept / ignore RIPv1 packets when authentication is in use. The default option is Maximum. The list contains:
  • Minimum—sets the security status for the RIP domain context as minimum. When minimum security is set, the RIP packets will be accepted even when authentication is in use.
  • Maximum—sets the security status for the RIP domain context as maximum. When maximum security is set, RIP packets will be ignored when authentication is in use.

• OutputDelay—select Output Delay status for the RIP Domain Context. The default option is Disabled. The list contains:
  • Enabled—sets Output Delay status as Enabled and enables interpacket delay for RIP updates, where the delay between packets in a multiple-packet RIP update is in milliseconds. This interpacket delay feature helps in preventing the routing table from losing information due to flow of RIP update from high speed router to low speed router.
  • Disabled—sets Output delay status in the RIP Domain context as Disabled; thereby, disabling interpacket delay for RIP packets.
• Trusted Neighbour Feature—select Trusted Neighbour Feature for the RIP domain context. The default option is Enabled. The list contains:
  • Enabled—sets the Trusted Neighbour Feature status as Enabled. When Enabled, a list of routers’ IP addresses can be configured. RIP Packets from those routers will be processed by RIP, and packets from other routers will be dropped.
  • Disabled—sets the Trusted Neighbour Feature status as Disabled. When Disabled, RIP Packets from all routers will be processed.
• Auto-Summary Status—select the Auto Summary status for the RIP domain context. The default option is Enabled. The list contains:
  • Enabled—sets the Auto Summary Status for the RIP domain context as Enabled. When Enabled, summary routes are sent in regular updates for both RIP version 1 and version 2. The summary is sent only if at least one subnet route, which is different from the interface over which the update is sent, is learned over an interface.
  • Disabled—sets the Auto Summary Status for the RIP domain context as Disabled. When Disabled, either individual subnet route is sent, or subnet routes are sent based on the specific aggregation configured over the interface.
• Retransmission Timeout Interval—enter the timeout interval to be used to retransmit the update request packet or an unacknowledged update response packet. The packets are transmitted at the specified interval till a response is received or the maximum number of retries is reached. The value ranges from 5 to 10. The default value is 5.
• Maximum Retransmitions—enter the maximum number of retransmissions of the update request and update response packets. If no response is received. the routes via the next hop router are marked unreachable. This value ranges from 10 to 40 seconds. The default value is 36.
• Distance—enter the distance value for the specified context id. This value ranges from 1 to 255. The default value is 121.

  • Enabled—activates RIP2 process throughout the system.
  • Disabled—disables RIP2 process in the system.
  • Passive—runs RIP2 process as a passive one.
• Split Horizon—select the operational status of split horizon in the system. The default option is Poison Reverse. The list contains:
  • Split Horizon—enables the Split Horizon updates for the RIP which prevents the routing loops in distance routing protocol. This is done by prohibiting the router from advertising a route back onto the interface. The Split Horizon updates are applied in the response packets sent.

• Split Horizon—the list contains (cont):
  • Poisson Reverse—enables the poison updates for the RIP which sends route with the metric value 16 on an interface from which route is learnt.
  • Disabled—disables Split Horizon updates for the RIP which sends route on all interfaces with the metric same as that in the RIP Routing Table.
• Default Route Installation—select the default route installation status in the RIP Interface. The default option is No. The list contains:
  • Yes—enables default route installation which installs the default route received in updates to the RIP database.
  • No—disables default route installation which blocks the installation of default route received in updates to the RIP database.
• Send Version—select the version of RIP packets that will be sent by the router. The default option is RIP1 Compatible. The list contains:
  • Do not send—stops the IP RIP transmitting advertisements to be sent on a VLAN interface / router port
  • RIP Version1 sends only RIP updates compliant with RFC 1058.
  • RIP1 Compatible—sends both Multicasting RIP updates and RIP updates compliant with RFC 1058 on the interface.
  • RIP Version2—sends only Multicasting RIP updates on the interface
• Receive Version—select the version of RIP updates to be received. The default option is RIP1 or RIP2. The list contains:
  • RIP1—receives only RIP updates compliant with RFC 1058 on the interface.
  • RIP2—receives only multicasting RIP updates on the interface.
  • RIP1 or RIP2—receives both multicasting RIP updates and RIP updates compliant with RFC 1058 on the interface.
  • Do not receive—sets that no IP RIP transmitting advertisements are received on a VLAN interface / router port.
• Route Age Timer—enter the time (in sec) after which the route entry goes in garbage collect (marked as invalid). The value is from 30 to 500 sec—default 180.
• Update Timer—enter the time interval (in seconds) at which the RIP updates should be sent. This is the fundamental timing parameter of the routing protocol. The value ranges from 10 to 3600 seconds. The default value is 30.
• Garbage Timer—enter the time (in seconds) after which the route entry marked as invalid is deleted. The advertisement of this entry is set to INFINITY while sending to others. The value ranges from 120 to 180 seconds with a default of 120.
• Rip Default Originate—enter the metric to be used for default route propagated over the VLAN interface / router port in a RIP update message and generates a default route into RIP. This value ranges from 0 to 15. The default option is 0 which implies that origination of default route over the interface is disabled.
