SecureXL keeps forwarding packets in VSX bridge mode when the member is down Technical Level
Symptoms
  • SecureXL keeps forwarding traffic on VSX Cluster in bridge mode, even though the member is down.

  • Running the 'ClusterXL_admin down' command switches in between the cluster level, but not falling over the traffic.

  • Running cpstop and turning off interface works correctly and the traffic failover as it should.

  • The VSX Cluster is only passing through BGP traffic.

Cause

The cluster member still forwards BFDv1 (Bidirectional Forwarding Detection) packets, and this leads to the fact, that BFDv1 is not triggering the BGP Routing to prioritize the second Path via cluster member 2, which cause a slow failover of the BGP routing and the loss of connections.
