Table 48: Terms Configuration Parameters (continued)
Field Function
Protocol Specifies the name of the protocol from which the route was
learned or to which the route is being advertised.
Action tab
Action Specifies the action to take if the conditions match.
Default Action Specifies that any action that is intrinsic to the protocol is
overridden. This action is also nonterminating, so that various
policy terms can be evaluated before the policy is terminated.
Next Specifies the default control action if a match occurs, and
there are no further terms in the current routing policy.
Priority 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 Specifies the BGP origin attribute.
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
optimize VPLS traffic flows across multiple paths.
Tag Specifies the tag value. The tag action sets the 32-bit tag field
in OSPF external link-state advertisement (LSA) packets.
Metric Changes the metric (MED) value by the specified negative or
positive offset. This action is useful only in an external BGP
(EBGP) export policy.
