Configuring a Mesh Group on an NBMA Network

Configuring a Mesh Group on an NBMA Network

Pre-configuration Tasks

Before configuring a mesh group, complete the following task:


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. (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.

  4. 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 ] ]
