  2. jslaven says:

    In IOS XR there is no concept of default address family. An address family must be explicitly configured under the BGP router configuration for the address family to be activated in BGP.

    Similarly, an address family must be explicitly configured under a neighbor for the BGP session to be activated under that address family.

  3. waseem says:

    there appears to be some limitation when it comes to configure simulation;

    agreed, you do have to configure address-family explicitly when it comes to BGP sessions under neighbor however you can’t ‘redistribute connected’ and no need for ‘bgp router-id.’
