Rip version 2 triggered updates

Triggered updates are exactly how they sound. Updates are not send to neighboring routers unless one of four things happen to cause the update to be sent which include the following;. The configuration of triggered updates is done on a per interface basis and must be configured on both sides of the link. The command used to enable triggered updates is ip rip triggered You can verify the configuration via the show ip protocols command. In this lab you will configure triggered updates on the point to point Frame relay link between R2 and R3.

Objective 1. The router receives a specific request for an update. Information from another interfaces has caused a modification to the RIP database causing an update to be triggered.

RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops allowed for RIP is This hop limit, however, also limits the size of networks that RIP can support. RIPv2 is actually an enhancement of RIPv1's features and extensions raether than an entirely new protocol. Unicast addressing is still allowed for special applications.

The version command is used to specify which RIP version to use either 1 or 2. The "network" command is used to specify the directly connected subnets on the router to be configured and that are intended to be included in the routing updates. According to the classful, network specified, the subnets of that network are automatically identified and participate in the routing update. By default routing updates are summarized at network boundaries.

In RIPv2 this auto summarization behavior can be turned off using the "no auto-summary" command. Moreover, manual summarization can be configured on a per interface level. FastEthernet0 2 2.
