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
Sources, on page 221
