Cluster occasionally stops forwarding multicast traffic
Symptoms
  • Cluster occasionally stops forwarding multicast traffic - multicast traffic does flow through the outgoing interface.

  • Output of Clish command 'show pim joins' shows PIM joins correctly.

  • Disabling or enabling SecureXL does not change anything.
Cause

/proc/net/ip_mr_cache and /proc/net/ip_mr_vif do not match the actual interfaces of multicast sender and multicast receivers.
