Configure which (S,G) entries from the multicast routing table
are advertised in SA messages.
By default, only sources within the local domain are advertised.
(Optional) For list access-list-name, enter the name or
number of an IP standard or extended access list. The
range is 1 to 99 for standard access lists and 100 to 199
for extended lists. The access list controls which local
sources are advertised and to which groups they send.
(Optional) For asn aspath-access-list-number, enter the
IP standard or extended access list number in the range 1
to 199. This access list number must also be configured in
the ip as-path access-list command.
(Optional) For route-map map, enter the IP standard or
extended access list number in the range 1 to 199. This
access list number must also be configured in the ip
as-path access-list command.
The switch advertises (S,G) pairs according to the access list
or autonomous system path access list.
