Cisco RPL vs Huawei XPL Route Policy Language Configuration

 

Cisco uses RPL (Route Policy Language) while Huawei uses XPL (Extended Route Policy language). Basically they are the same concept but of course the commands are slightly different, though editing the policy or prefix-set requires vi/vim knowlege.

Adding Prefix-Set:
xpl ip-prefix-list FNT-Prefixes

Creating Route Policy:
route-policy FNT-EXPORT
  if (destination in FNT-Prefixes) then
    prepend as-path 65555 2
