| Action | ||
Action | Specifies the action to take if the conditions match. | Select a value from the list. |

AS Path Prepend | 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 nonconfederation sequence. | Enter AS path prepend value. |
| AS Path Expand | ||
Type | 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.

This policy action allows you to optimize VPLS traffic flows across multiple paths. | Select the check box to enable the option. |
| Tag | ||
Action | Specifies the tag value. The tag action sets the 32-bit tag field in OSPF external link-state advertisement (LSA) packets. | Select the action and type a value. |
