Configuring a redundancy group node
![[IMPORTANT: ]](images/important.png) | IMPORTANT: For a redundancy group to operate correctly, make sure the track entries associated with any node of the redundancy group monitor the physical layer state of interfaces. | |
When you configure a redundancy group node, follow these restrictions and guidelines:
You can configure a maximum of two nodes for a redundancy group. Nodes in different redundancy groups can use the same ID.
You can create only one-to-one bindings between redundancy group nodes and IRF member devices. You cannot change the binding for a node if the node has member interfaces or is associated with track entries.
Before you assign member interfaces to a redundancy group node, you must bind the node to an IRF member device. The member interfaces must be physical ports on the IRF member device. You cannot assign members of Reth interfaces to the node. An interface can be assigned to only one redundancy group node.
You cannot associate a track entry with both nodes in a redundancy group.
On the high-priority node, do not exclude a subinterface from the shutdown action of the Reth module if both the subinterface and its main interface have one of the following roles:
Member of the redundancy group.
Member of a Reth interface in the redundancy group.
When the Reth module shuts down the main interface, the subinterface is also shut down. The shutdown subinterface cannot recover automatically to trigger an automatic switchover.
To configure a redundancy group node:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter redundancy group view. | redundancy group group-name | N/A |
3. Create a redundancy group node and enter its view. | node node-id | By default, no redundancy group nodes exist. |
4. Set the priority of the redundancy group node. | priority priority | By default, the priority of a redundancy group node is 1. |
5. Bind the redundancy group node to an IRF member device (in IRF mode). | bind slot slot-number | By default, a node is not bound to an IRF member device. |
6. (Optional.) Assign a member interface to the redundancy group node. | node-member interface interface-type interface-number | By default, a redundancy group node does not have member interfaces. |
7. Associate an existing track entry with the redundancy group node. | track track-entry-number [ reduced weight-reduced ] [ interface interface-type interface-number ] | By default, a node is not associated with track entries. |
