Configuring FIB compression

Use the following procedure to enable FIB compression on the SLX 9540 and SLX 9640 devices.

1. Enter hardware configuration mode.
   

   device# config
   device(config)# hardware
   device(config-hardware)# 

2. Enable FIB compression by using the profile route route-enhance command as in the following example for both IPv4 and IPv6 compression.
   

   device(config-hardware)# profile route route-enhance v4_fib_comp v6_fib_comp on
   

3. Confirm the configuration by using the show hw route-info command for an interface.
   

   device# show hw route-info interface 1/2
