OSPF adjacencies repeatedly disconnect on VSNext Cluster

Product: VSNext
Version: R82
Last Modified: 2026-05-26

Symptoms

• OSPF adjacencies repeatedly disconnect on VSNext Cluster.
• OSPF neighbors receive Hello packets, but adjacency resets occur, causing routing instability.
• The routed log shows that we receive the interfaces later via task_ifaddr_change().
• Example log output in /var/log/messages:

[routed] ClusterXL: Missing virtual addresses for VLANs on bond'x'. Ports treated as non-clustered.
[OSPF] Adjacency with neighbor reset. Reason: conflicting advertisements.

• The output of the Clish "show routed cluster-state" command shows that both Cluster members appear in Master state.

Cause

A Cluster issue in VSnext causes more than one member to become Master, resulting in OSPF instability.
