The components that have to be updated for the other MXs are:

  • The fxp0 interface addresses

  • The loopback interface address

  • The internal interfaces (addresses and OSPF)

  • The external interfaces (addresses and BGP)

  • The exterior BGP groups

The policies and the firewall filters are all generic in nature, except for the customer-specific policies. The use of the apply lists eliminates the manual labor for the prefix lists. By using show | display set and Notepad, the configurations for the remaining backbone MXs can easily be created.

Once the configurations were loaded, we were able to verify that BGP was set up correctly with:
