Configuring MSDP Global Parameters

You can configure the optional MSDP global parameters described below:

Originator interface name -- IP address used in the RP field of an SA message entry. When Anycast RPs are used, all RPs use the same IP address. You can use this parameter to define a unique IP address for the RP of each MSDP peer. By default, the software uses the RP address of the local system. Note that we recommend that you use a loopback interface for the RP address.
Group-limit -- Maximum number of (S, G) entries that the software creates for the specified prefix. The software ignores groups when the group limit is exceeded and logs a violation. By default, no group limit is defined.
SA interval -- Interval at which the software transmits Source-Active (SA) messages. The range is from 60 to 65,535 seconds. The default is 60 seconds.

For more information, see the Cisco Nexus 9000 Series NX-OS Multicast Routing Configuration Guide, Release 7.x.
