Table 524 loop-detect command
Description This command enables setting the BGP local-preference attribute in incoming routes if not
specified and configures the default value for the attribute. This value is used if the BGP route
arrives from a BGP peer without the local-preference integer set.
The specified value can be overridden by any value set via a route policy. This configuration
parameter can be set at three levels: global level (applies to all peers), group level (applies to
all peers in peer-group) or neighbor level (only applies to specified peer). The most specific
value is used.
The no form of the command at the global level specifies that incoming routes with
local-preference set are not overridden and routes arriving without local-preference set are
interpreted as if the route had local-preference value of 100.
The no form of the command used at the group level reverts to the value defined at the global
level.
The no form of the command used at the neighbor level reverts to the value defined at the
group level.
Default no local-preference — Does not override the local-preference value set in arriving routes and
analyze routes without local preference with value of 100.
Parameters local-preference — The local preference value to be used as the override value, expressed as
a decimal integer.
