Configuring MSDP Peers
An MSDP router must know which routers are its peers. You define the peer relationships explicitly by configuring the neighboring routers that are the MSDP peers of the local router. After peer relationships are established, the MSDP peers exchange messages to advertise active multicast sources. You must configure at least one peer for MSDP to function.
To configure MSDP peers, include the peer statement:
peer address {disable;active-source-limit {maximum number;threshold number;}authentication-key peer-key;default-peer;export [ policy-names ];import [ policy-names ];local-address address;traceoptions {file filename <files number> <size size> <world-readable |
no-world-readable>;flag flag <flag-modifier> <disable>;}}
The peer and the local-address statements are required.
You can configure MSDP peers globally or in a group.
- Globally for all MSDP peers at the following hierarchy
levels:
- [edit protocols msdp]
- [edit logical-systems logical-system-name protocols msdp]
- [edit routing-instances routing-instance-name protocols msdp]
- [edit logical-systems logical-system-name routing-instances routing-instance-name protocols msdp]
- In a group at the following hierarchy levels:
- [edit protocols group group-name]
- [edit logical-systems logical-system-name protocols group group-name]
- [edit routing-instances routing-instance-name protocols group group-name]
- [edit logical-systems logical-system-name routing-instances routing-instance-name protocols group group-name]
If you configure MSDP peers in a group, each individual peer in a group inherits all group-level options.
