Configuring MSDP
Redistributing Sources
SA messages originate on RPs to which sources have registered. By default, any source that registers
with an RP is advertised. The
A flag is set in the RP when a source is registered, which means the source
is advertised in an SA unless it is filtered.
Beginning in privileged EXEC mode, follow these steps to further restrict which registered sources are
advertised. This procedure is optional.

advertised in SA messages.

(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.
