  1. In the RIP Settings dialog, do the following:

    1. Default Metric: Choose the default hop count from 1 to 16. RIP uses the hop count as the metric for determining the number of routers (hops) from the source router through which data must travel to reach the destination. RIP supports up to 15 hops, and a hop count of 16 is considered inaccessible.

    2. Receive Version: Choose the RIP version you want to use for incoming traffic on the interface. RIP version 1 is an open-standard classful protocol, and it works with most routers. RIP version 2 supports CIDR (Classless Inter-Domain Routing), can carry subnet information, supports authentication, and can perform subnetting and multicasting. For an HA configuration, select 2 as the receive version.

    3. Send Version: Choose the RIP version you want to use for outgoing traffic on the interface. For an HA configuration, select 2 as the send version.

    4. ECMP: By default, this field is set to Enabled.

    5. Interfaces: Only the LAN interface is supported.

    6. Timer Settings:

      1. Flush Interval: Enter the number of seconds that must pass before the router removes an inaccessible route from its routing table. The default is 120 seconds. 

      2. Holddown Interval: Enter the number of seconds within which the routing information about better routing paths is suppressed to prevent the router from learning about a failed path. A routing path enters the hold-down state when an update packet indicates that the path is inaccessible. When the hold-down interval expires, better paths advertised by other sources are accepted and the path is no longer inaccessible. The default hold-down interval is 180 seconds.

      3. Update Interval: Enter the number of seconds within which the routing paths learned by RIP are advertised to neighbors. This is the time interval between routing updates. The default is 30 seconds.

    7. Inject Routes: Click the Add button, and specify the IP address for the inject route.
