Configuring a Mesh Group on an NBMA Network
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- (Optional) On an Ethernet interface, run undo portswitch
The interface is switched to Layer 3 mode.
By default, an Ethernet interface works in Layer 2 mode.
Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
- Run isis mesh-group { mesh-group-number | mesh-blocked }
The interface is added to a mesh group.
When mesh-blocked is configured on an interface, the interface is blocked and cannot flood LSPs outside. All the interfaces added to a mesh group implement global LSDB synchronization through CSNP and PSNP mechanisms.
Verifying the Configuration
Run the following commands to check IS-IS process statistics.
- display isis statistics [ updated-lsp [ history ] ] [ level-1 | level-2 | level-1-2 ] [ process-id | vpn-instance vpn-instance-name ]
- display isis process-id statistics [ [ [ updated-lsp [ history ] ] [ level-1 | level-2 | level-1-2 ] ] | packet ]
