Configuring Multicast Source Discovery Protocol (MSDP)<br />
<strong>Brocade</strong>(config)# router msdp vrf blue<br />
<strong>Brocade</strong>(config-msdp-router-vrf-blue)# no msdp-peer 205.216.162.1<br />
Syntax: [no] msdp-peer ip-addr shutdown<br />
The ip-addr parameter specifies the IP address of the MSDP peer that you want to disable.<br />
Designating the interface IP address as the RP IP address<br />
When an RP receives a Source Active message, it checks its PIM Sparse multicast group table for<br />
receivers for the group. If a receiver exists the RP sends a Join to the source.<br />
By default, the IP address included in the RP address field of the SA message is the IP address of<br />
the originating RP. An SA message can use the IP address of any interface on the originating RP.<br />
(The interface is usually a loopback interface.)<br />
To designate an interface IP address to be the IP address of the RP, enter commands such as the<br />
following.<br />
<strong>Brocade</strong>(config)# interface loopback 2<br />
<strong>Brocade</strong>(config-lbif-2)# ip address 2.2.1.99/32<br />
<strong>Brocade</strong>(config)# router msdp<br />
<strong>Brocade</strong>(config-msdp-router)# originator-id loopback 2<br />
<strong>Brocade</strong>(config-msdp-router)# exit<br />
To specify VRF information, enter the following commands at the MSDP VRF configuration level.<br />
<strong>Brocade</strong>(config)# interface loopback 2<br />
<strong>Brocade</strong>(config-lbif-2)# ip address 2.2.1.99/32<br />
<strong>Brocade</strong>(config)# router msdp vrf blue<br />
<strong>Brocade</strong>(config-msdp-router-vrf blue)# originator-id loopback 2<br />
<strong>Brocade</strong>(config-msdp-router-vrf blue)# exit<br />
Syntax: [no] originator-id type number<br />
The originator-id parameter instructs MSDP to use the specified interface IP address as the IP<br />
address of the RP in an SA message. This address must be the address of the interface used to<br />
connect the RP to the source. The default address used is the RP IP address.<br />
The type parameter indicates the type of interface used by the RP. Ethernet, loopback and virtual<br />
routing interfaces (ve) can be used.<br />
The number parameter specifies the interface number (for example: loopback number, port<br />
number or virtual routing interface number.)<br />
Filtering MSDP source-group pairs<br />
You can filter individual source-group pairs in MSDP Source-Active messages:<br />
• sa-filter in – Filters source-group pairs received in Source-Active messages from an MSDP<br />
neighbor.<br />
• sa-filter originate – Filters self-originated source-group pairs in outbound Source-Active<br />
messages sent to an MSDP neighbor<br />
• sa-filter out – Filters self-originated and forwarded source-group pairs in outbound<br />
Source-Active messages sent to an MSDP neighbor<br />
