Configuring MSDP
Command
Step 1
configure terminal
Step 2
ip msdp sa-filter in ip-address | name
or
ip msdp sa-filter in {ip-address | name}
list access-list-number
or
ip msdp sa-filter in {ip-address | name}
route-map map-tag
Step 3
access-list access-list-number {deny |
permit} protocol source source-wildcard
destination destination-wildcard
Step 4
end
Step 5
show running-config
Step 6
copy running-config startup-config
To remove the filter, use the no ip msdp sa-filter in {ip-address | name} [list access-list-number]
[route-map map-tag] global configuration command.
This example shows how to filter all SA messages from the peer named switch.cisco.com:
Switch(config)# ip msdp peer switch.cisco.com connect-source gigabitethernet1/0/1
Switch(config)# ip msdp sa-filter in switch.cisco.com
78-15870-01
Purpose
Enter global configuration mode.
Filter all SA messages from the specified MSDP peer.
or
From the specified peer, pass only those SA messages that pass the IP
extended access list. The range for the extended access-list-number
is 100 to 199.
If both the list and the route-map keywords are used, all conditions
must be true to pass any (S,G) pair in incoming SA messages.
or
From the specified MSDP peer, pass only those SA messages that meet
the match criteria in the route map map-tag.
If all match criteria are true, a permit from the route map passes routes
through the filter. A deny will filter routes.
(Optional) Create an IP extended access list, repeating the command as
many times as necessary.
•
For access-list-number, enter the number specified 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.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
