Configuring Multicast Source Discovery Protocol (MSDP)
1
Syntax: [no] msdp-peer ip-addr shutdown
The ip-addr parameter specifies the IP address of the MSDP peer that you want to disable.
Designating the interface IP address as the RP IP address
When an RP receives a Source Active message, it checks its PIM Sparse multicast group table for
receivers for the group. If a receiver exists the RP sends a Join to the source.
By default, the IP address included in the RP address field of the SA message is the IP address of
the originating RP. An SA message can use the IP address of any interface on the originating RP.
(The interface is usually a loopback interface.)
To designate an interface IP address to be the IP address of the RP, enter commands such as the
following.
Brocade(config)# interface loopback 2
Brocade(config-lbif-2)# ip address 2.2.1.99/32
Brocade(config)# router msdp
Brocade(config-msdp-router)# originator-id loopback 2
Brocade(config-msdp-router)# exit
To specify VRF information, enter the following commands at the MSDP VRF configuration level.
Brocade(config)# interface loopback 2
Brocade(config-lbif-2)# ip address 2.2.1.99/32
Brocade(config)# router msdp vrf blue
Brocade(config-msdp-router-vrf blue)# originator-id loopback 2
Brocade(config-msdp-router-vrf blue)# exit
Syntax: [no] originator-id type number
The originator-id parameter instructs MSDP to use the specified interface IP address as the IP
address of the RP in an SA message. This address must be the address of the interface used to
connect the RP to the source. The default address used is the RP IP address.
The type parameter indicates the type of interface used by the RP. Ethernet, loopback and virtual
routing interfaces (ve) can be used.
The number parameter specifies the interface number (for example: loopback number, port
number or virtual routing interface number.)
Filtering MSDP source-group pairs
You can filter individual source-group pairs in MSDP Source-Active messages:
• sa-filter in – Filters source-group pairs received in Source-Active messages from an MSDP
neighbor.
• sa-filter originate – Filters self-originated source-group pairs in outbound Source-Active
messages sent to an MSDP neighbor
• sa-filter out – Filters self-originated and forwarded source-group pairs in outbound
Source-Active messages sent to an MSDP neighbor
Filtering incoming and outgoing Source-Active messages
The following example configures filters for incoming Source-Active messages from three MSDP
neighbors:
