| - Identifier for the path when using BGP ADD-PATHS for the SR-TE
policy SAFI.
- Reference to the path-id list key
- When the BGP speaker supports advertisement of multiple
paths for a prefix, the path identifier is used to
uniquely identify a route based on the combination of the
prefix and path id. In the Adj-RIB-In, the path-id value is
the value received in the update message. In the Loc-RIB,
if used, it should represent a locally generated path-id
value for the corresponding route. In Adj-RIB-Out, it
should be the value sent to a neighbor when add-paths is
used, i.e., the capability has been negotiated.
- If the route is learned from a neighbor, the path-id
corresponds to the path-id for the route in the
corresponding adj-rib-in-post table. If the route is
injected from another protocol, or the neighbor does not
support BGP add-paths, the path-id should be set
to zero, also the default value.
- Reference to the path identifier for the SR-TE Policy SAFI
route. The value is only non-zero if ADD-PATHS is not being
used.
- Reference : draft-ietf-idr-add-paths - Advertisement of Multiple Paths
in BGP
- The default value is : 0
