Enable BGP PIC

BGP PIC is disabled by default.
  1. Enter global configuration mode.
    device# configure terminal
  2. Enable BGP.
    device(config)# prefix-independent-convergence
  3. Confirm the configuration. Backup paths are not displayed in the output.
    device(config)# show running-config
  4. Confirm changes in the next-hop path.
    device(config)# show ip route
    IP Routing Table for VRF "default-vrf"
    Total number of IP routes: 2
    '*' denotes best ucast next-hop
    '[x/y]' denotes [preference/metric]
    
    10.20.30.0/24,
        *via DIRECT, Null0, [1/1], 0m11s, static, tag 0
    10.20.31.0/24,
        *via DIRECT, Null0, [1/1], 0m5s, static, tag 0
    

    Although the route remains untouched in hardware, the timestamps (highlighted in the example) reflect changes in the next-hop path.

The following example summarizes the commands in this procedure.
device# configure terminal
device(config)# prefix-independent-convergence
device(config)# show running-config
device(config)# show ip route
