Routing Protocols

  • When the multicast stream has IRB as receivers with IGMP/MLD snooping enabled in the particular bridge or VLAN, there can be traffic loss for 3 minutes by default up to 5 minutes (based on the GR configuration for MCSNOOPD) when the snooping configuration is removed. The multicast traffic streams recover and flooding for IRB receiver in the VLAN is seen as expected. PR1550523
