Release Information

Statement introduced before JUNOS Release 7.4.

Statement introduced in JUNOS Release 9.0 for EX Series switches.

Description

Modify the value of the LOCAL_PREF path attribute, which is a metric used by IBGP sessions to indicate the degree of preference for an external route. The route with the highest local preference value is preferred.

The LOCAL_PREF path attribute always is advertised to internal BGP peers and to neighboring confederations. It is never advertised to external BGP peers.

Default

If you omit this statement, the LOCAL_PREF path attribute, if present, is not modified.

Options

local-preference—Preference to assign to routes learned from BGP or from the group or peer.

Range: 0 through 4,294,967,295 (232 – 1)
Default: If the LOCAL_PREF path attribute is present, do not modify its value. If a BGP route is received without a LOCAL_PREF attribute, the route is handled locally (it is stored in the routing table and advertised by BGP) as if it were received with a LOCAL_PREF value of 100. By default, non-BGP routes that are advertised by BGP are advertised with a LOCAL_PREF value of 100.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
