-This command configures a route to be originated into BGP, just as with the
-previous command, but additionally sets an AS-Pathlimit TTL to be advertised
-on the route. See draft-ietf-idr-as-pathlimit.
-
-Specifying a TTL of 0 can be used to remove pathlimit from a previously
-configured network statement.
-
-Note that when advertising prefixes with AS-Pathlimit set, all less-specific
-prefixes advertised SHOULD also have the Atomic-Aggregate attribute set.
-Failure to do so increases the risks of accidental routing loops occuring.
-
-This implementation will try to automatically set Atomic-Aggregate as
-appropriate on any less-specific prefixes originated by the same speaker,
-however it will not (and often can not) do so where @b{other} speakers in
-the AS are originating more specifics.
-
-Hence the system administrator must take care to ensure that all
-less-specific prefixes originated carry atomic-aggregate as appropriate, by
-manually configuring speakers originating less-specifics to set
-Atomic-Aggregate on those advertisements!
