Action

Action

Select an action value from the list.

Default Action

Select a value from the list.

Specifies that any action that is intrinsic to the protocol is overridden. This action is also non terminating so that various policy terms can be evaluated before the policy is terminated.

Next

Select a value from the list.

Specifies the default control action if a match occurs, and there are no further terms in the current routing policy.

Priority

Select a value from the list.

Specifies a priority for prefixes included in an OSPF import policy. Prefixes learned through OSPF are installed in the routing table based on the priority assigned to the prefixes.

BGP Origin

Select a value from the list.

Specifies the BGP origin attribute.

AS Path Prepend

Enter AS path prepend value.

Affixes an AS number at the beginning of the AS path. AS numbers are added after the local AS number has been added to the path. This action adds an AS number to AS sequences only, not to AS sets. If the existing AS path begins with a confederation sequence or set, the affixed AS number is placed within a confederation sequence. Otherwise, the affixed AS number is placed with a non confederation sequence.

AS Path Expand

Enter the following details:

  • Type—Select the type and type a value.

    Extracts the last AS number in the existing AS path and affixes that AS number to the beginning of the AS path n times, where n is a number from 1 through 32. The AS number is added before the local AS number has been added to the path. This action adds AS numbers to AS sequences only, not to AS sets. If the existing AS path begins with a confederation sequence or set, the affixed AS numbers are placed within a confederation sequence. Otherwise, the affixed AS numbers are placed within a non confederation sequence. This option is typically used in non-IBGP export policies.

  • Value—Enter the As path value.

Preference

Enter the following details:

  • Action—Select the preference action and type a value.

  • Value—Enter the preference value.

Local Preference

Enter the following details:

  • Action—Select the action and type a value.

    Changes the metric (MED) value by the specified negative or positive offset. This action is useful only in an external BGP (EBGP) export policy.

  • Value—Enter the tag value.

Metric

Enter the following details:

  • Action—Select the action and type a value.

    Specifies that the value entered here maintains the packet counts for a route passing through your network, based on the source address.

  • Destination Class—Enter the destination class.

    Specifies the value entered here maintains packet counts for a route passing through your network, based on the destination address in the packet.

  • Forwarding Class—Enter the forwarding class.
