Purpose
Command or Action
Enters global configuration mode.
configure terminal
Example:
Device# configure terminal
Step 2
Enables a filter for outgoing SA request messages.
ip msdp filter-sa-request
{
peer-address
|
peer-name
}
[
list access-list
]
Step 3
Only one SA request filter can be configured
per MSDP peer.
Note
Example:
Device(config)# ip msdp filter sa-request
172.31.2.2 list 1
--
Repeat Step 3 to configure SA request filters for additional
MSDP peers.
Step 4
Exits global configuration mode and returns to
privileged EXEC mode.
exit
Example:
Device(config)# exit
Step 5
Including a Bordering PIM Dense Mode Region in MSDP
Perform this optional task to configure a border device to send SA messages for sources active in a PIM dense
mode (PIM-DM) region.
You can have a device that borders a PIM-SM region and a PIM-DM region. By default, sources in the
PIM-DM domain are not included in MSDP. You can configure this border device to send SA messages for
sources active in the PIM-DM domain. If you do so, it is very important to also configure the
ip msdp
redistribute
command to control what local sources from the PIM-DM domain are advertised. Not configuring
this command can result in the (S, G) state remaining long after a source in the PIM-DM domain has stopped
sending. For configuration information, see the
Controlling SA Messages Originated by an RP for Local
Sources, on page 195
section.
