The peer mesh-group command adds an MSDP peer to a mesh group.
The undo peer mesh-group command restores the default configuration.
| Parameter | Description | Value |
|---|---|---|
| peer-address | Specifies the address of an MSDP peer that is a member of a mesh group. | The value is in dotted decimal notation. |
| name | Indicates the name of a mesh group. | The value is a string with a maximum of 32 case sensitive characters. |
By default, the MSDP peer is not a member of any mesh Group.
Usage Scenario
If there are multiple MSDP peers on a network, Source Active (SA) messages may be flooded among these peers. Especially when many MSDP peers are configured in the same PIM-SM domain, Reverse Path Forwarding (RPF) rules cannot filter out useless SA messages effectively. Each MSDP peer needs to perform the RPF check on each received SA messages, which brings a heavy load to the system.
Adding multiple MSDP peers to the same mesh group can reduce the number of SA messages transmitted between these MSDP peers and release the system load.
Prerequisites
Before adding a new member to the mesh group by using the peer mesh-group command, configure the new member to set up the MSDP peer relationship with the other members in the mesh group.
