Upgrading to the AF Style

In order to have a smooth upgrade path, support has been added to parse the old-style 12.0S commands (which had the nlri keyword). These commands are as follows:

• neighbor

• network

• aggregate

• set nlri and match nlri in route maps

The only caveat is that the old-style commands can be used as long as no new features need to be activated. In that event, the old-style BGP commands need to be translated to the new style.

To migrate to the new command set, you must enter the bgp upgrade-cli command in router configuration mode:

Router(config-router)#bgp upgrade-cli

This command will translate the old configuration to the new one. As always, a wr mem will need to be done in order to save the new configuration. (Note: The bgp upgrade-cli command is not shown in the configuration.)
