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.

  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.

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.
