Configuring FIB compression

  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
