To configure the Multicast Source Discovery protocol (MSDP), include the msdp statement:




msdp {



active-source-limit {

maximum number;

threshold number;
}



data-encapsulation (disable | enable);

disable;

export [ policy-names ]; 

import [ policy-names ];

local-address address;

rib-group group-name;



traceoptions {
file filename <replace> <size size> <files number > <no-stamp> <world-readable | no-world-readable>;
flag flag <flag-modifier > <disable>; 
}





peer address {



active-source-limit {

maximum number;

threshold number;
}



authentication-key peer-key;

default-peer;

disable;

export [ policy-names ]; 

import [ policy-names ];

local-address address;



traceoptions {
file filename <replace> <size size> <files number> <no-stamp>
<world-readable | no-world-readable>;
flag flag <flag-modifier> <disable>; 
}


}





group group-name {

disable;

export [ policy-names ]; 

import [ policy-names ];

local-address address;

mode ( -group | standard );



traceoptions {
file filename <replace> <size size> <files number> <no-stamp>
<world-readable | no-world-readable>;
flag flag <flag-modifier> <disable>; 
}





peer address ; {



active-source-limit {

maximum number;

threshold number;
}



authentication-key peer-key;

default-peer;

disable;

export [ policy-names ]; 

import [ policy-names ];

local-address address;



traceoptions {
file filename <replace> <size size> <files number> <no-stamp>
<world-readable | no-world-readable>;
flag flag <flag-modifier> <disable>; 
}


}





source prefix/mask {



active-source-limit {

maximum number;

threshold number;
}


}


}


}

You can include this statement at the following hierarchy levels:

[edit protocols]
[edit routing-instances routing-instance-name protocols]
[edit logical-systems logical-system-name protocols]
[edit routing-instances routing-instance-name logical-systems logical-system-name protocols]

For an overview of logical systems and a detailed example of logical system configuration, see the logical systems chapter of the JUNOS Feature Guide.

By default, MSDP is disabled.

For a configuration example, see Example: Configuring MSDP.

This chapter describes the following tasks for configuring MSDP:
