enable lpm
enable lpm
Description
Enables Selective-LPM routing.
Syntax Description
This command has no arguments or variables.
Default
Default is disabled.
Usage Guidelines
This command alters the state of the Selective-LPM routing feature (which is disabled by default). If
Accounting is disabled, non-MPLS traffic to known routes is forwarded by hardware and the MSM CPU
is used for slow-path traffic. When LPM is enabled, slow-path traffic is forwarded by the MPLS/ARM
module at a faster rate. Also, if LPM is enabled, fast-path traffic to specified vlans or route-maps can be
forwarded using longest prefix match on the module without installing IP FDB entries.
Example
The following command enables the Selective-LPM feature:
enable lpm
