default-information-originate

This command enables the generation and sending of the default route, if it is registered in the routing table of the FIB, for:

  • NSSA areas (route advertising) as NSSA-LSA;
  • BGR IPv4/IPv6 address family.

The use of a negative form (no) of the command disables the route generation by default.
