Parameters 
mesh-group-number: Mesh group number, ranging from 1 to 4294967295.  
mesh-blocked: Blocks the interface, which sends LSPs only after receiving LSP requests. 
Description 
Use the isis  mesh-group command to add the interface into a specified mesh group or block the 
interface.  
Use the undo isis mesh-group command to restore the default.  
By default, an interface does not belong to any mesh group.  
For an interface not in a mesh group, it follows the normal process to flood the received LSPs to other 
interfaces. For the NBMA network with high connectivity and multiple point-to-point links, this will cause 
repeated LSP flooding and bandwidth waste.  
After an interface is added to a mesh group, it will only flood a received LSP or a generated LSP to 
interfaces not belonging to the same mesh group. 
If you block an interface, the interface can send LSPs only after receiving LSP requests. 
 
 
The mesh-group feature is only available for a point-to-point link interface.  
This command is not available in loopback interface view.
