Configuring MSDP Peers

You can configure an MSDP peer when you configure a peering relationship with each MSDP peer that resides either within the current PIM domain or in another PIM domain. MSDP is enabled on the router when you configure the first MSDP peering relationship.

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

Prerequisites:

Ensure that you have enabled PIM and MSDP.
Ensure that you configured PIM in the domains of the routers that you will configure as MSDP peers.

This example configures an MSDP peer.

CLI Commands

The CLI commands and options listed below are the equivalent to the payload example displayed in the pane on the right.

ip msdp peer 192.0.20.123 connect-source eth1/9 remote-as 200
ip msdp description 192.0.20.123 This is an example of a peer
ip msdp keepalive 192.0.20.123 50 70
ip msdp shutdown 192.0.20.123
ip msdp sa-limit 192.0.20.123 9999999
ip msdp password 192.0.20.123 0 asdfzxcv1234

Note: The property information for this example was added in Release 9.3(3).

Verifying a DME Configuration
The following table contains the distinguished name (DN) for each managed object (MO) in the DME payload. Issue a GET request using the DN to verify the configuration was posted or to get information about the configured properties of a particular object.

MO	DN
msdpDom	sys/msdp/inst/dom-{name}
msdpPeer	sys/msdp/inst/dom-{name}/peer-{[addr]}
msdpAuthP	sys/msdp/inst/dom-{name}/peer-{[addr]}/auth

msdpDom Properties

The following table contains information about the msdpDom properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
name	naming:Name256 (string:Basic)	The name of the object.	MAX SIZE: 63

msdpPeer Properties
