Select the IPv6 precedence option here. Options to choose from are Routine, Priority, Immediate, Flash, Flash Override, Critical, Internet, and Network. Use this feature to set the precedence value in the IPv6 header. This option only takes effect when policy routing involves the IPv6 packet. Select and enter the metric value here that will be used in the modification. The range is from 0 to 4294967294. Select the metric type here that will be used in the modification. Options to choose from are Type-1 and Type-2. • Type-1 - Specifies to use the OSPF external type-1 metric. • Type-2 - Specifies to use the OSPF external type-2 metric. Select the origin option here that will be used in the modification. Options to choose from are: • IGP - Specifies that the prefix is originated from an Interior Gateway Protocol. • EGP - Specifies that the prefix is originated from an Exterior Gateway Protocol. • Incomplete - Specifies that the prefix is originated from an unknown source. Select and enter the weight value here that will be used in the modification. The range is from 0 to 65535. Select and enter the AS path value here that will be used in the modification. Select and enter the dampening values here. There are 5 places where we can enter value here. They are listed below in order from top to bottom: • Half Life Time - Enter the half-life time value here after which the penalty of the reachable routes is decreased by half. The range is from 1 to 45 minutes. • Reuse Value - Enter the re-use value here. This specifies that if the penalty of a route is lower than this value, the route is unsuppressed. The range is 1 to 20000. • Suppress Value - Enter the suppress value here. This specifies that if the penalty of a route is higher than this value, the route is suppressed. The range is from 1 to 20000. • Max Suppress Time - Enter the maximum suppress time value here that a route can be suppressed. The range is from 1 to 255 minutes. • Unreachable Route's Half Life - Enter the unreachability half-life time value here after which the penalty of the unreachable routes is decreased by half.
