Field Function
AS Path Prepend Affixes an AS number at the beginning of the AS path. The 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.
AS Path Expand 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 nonconfederation sequence. This option is typically used in
non-IBGP export policies.
Load Balance Per Specifies that all next-hop addresses in the forwarding table
Packet must be installed and have the forwarding table perform
per-packet load balancing. This policy action allows you to

in OSPF external link-state advertisement (LSA) packets.
