Protocols And Standards; Mld Snooping Configuration Task List; Mld Snooping Configuration Task List For Vlans - HP FlexFabric 5950 series Configuration Manual

The MLD snooping proxy device processes different MLD messages as follows:
•
General query.
After receiving an MLD general query, the device forwards the query to all ports in the VLAN
except the receiving port. The device also generates an MLD report based on the local
membership information and sends the report to all router ports.
•
Multicast-address-specific query or multicast-address-and-source-specific query.
After receiving an MLD multicast-address-specific query or
multicast-address-and-source-specific query, the device forwards the query to all ports in the
VLAN except the receiving port. If the forwarding entry has a member port, the device sends a
response to all router ports in the VLAN.
•
Report.
After receiving an MLD report from a host, the device looks up the forwarding table for a
matching entry as follows:
If a match is found and the matching forwarding entry contains the receiving port, the device

resets the aging timer for the port.
If a match is found but the matching forwarding entry does not contain the receiving port, the

device adds the receiving port to the outgoing interface list. It also marks the receiving port
as a dynamic member port and starts an aging timer for the port.
If no match is found, the device creates a forwarding entry with the receiving port as an

outgoing interface. It also marks the receiving port as a dynamic member port and starts an
aging timer for the port. Then it sends the report to all router ports.
•
Done message.
After receiving the MLD done message on a port, the device sends an MLD
multicast-address-specific query through the receiving port. The device sends the MLD done
message to all router ports only when the last member port is removed from the forwarding
entry.
