Configuring MSDP
To remove the filter, use the
no ip msdp redistribute
global configuration command.
Filtering Source-Active Request Messages
By default, only switches that are caching SA information can respond to SA requests. By default, such
a switch honors all SA request messages from its MSDP peers and supplies the IP addresses of the active
sources.
However, you can configure the switch to ignore all SA requests from an MSDP peer. You can also
honor only those SA request messages from a peer for groups described by a standard access list. If the
groups in the access list pass, SA request messages are accepted. All other such messages from the peer
for other groups are ignored.

Create an IP standard access list, repeating the command as many times
as necessary.
or
Create an IP extended access list, repeating the command as many times
as necessary.
•
For
access-list-number
, the range is 1 to 99 for standard access lists
and 100 to 199 for extended lists. Enter the same number created in
Step 2.
•
The
deny
keyword denies access if the conditions are matched. The
permit
keyword permits access if the conditions are matched.
•
For
protocol
, enter
ip
as the protocol name.
•
For
source
, enter the number of the network or host from which the
packet is being sent.
•
For
source-wildcard
, enter the wildcard bits in dotted decimal
notation to be applied to the source. Place ones in the bit positions
that you want to ignore.
•
For
destination
, enter the number of the network or host to which
the packet is being sent.
•
For
destination-wildcard
, enter the wildcard bits in dotted decimal
notation to be applied to the destination. Place ones in the bit
positions that you want to ignore.
Recall that the access list is always terminated by an implicit deny
statement for everything.
