Sub- aggregation group, judge sub- aggregation group whether comprising receiving the physical ports of the LLDP messages.If it is not, then this will be received
The physical port of LLDP messages adds in the sub- aggregation group.
It, can be from the son if the corresponding physical ports of purpose MAC of unicast message to be sent belong to the sub- aggregation group
Exit port is chosen in aggregation group and sends unicast message.
For example, when CB equipment receives the unicast message from external network, according to the SRPD in the unicast message
(Segment Routing Path Discriminator, section routed path descriptor), can obtain next-hop node equipment
MAC Address, i.e. some PE equipment MAC Address.Corresponding sub- polymerization is searched according to the MAC Address of next-hop node equipment
Group chooses exit port from the sub- aggregation group, and unicast message is sent directly to the PE equipment.
When multiple physical ports are included in group aggregation group, in order to realize load balancing, it can be determined by Hash operation
Exit port of one physical port as unicast message sends unicast message by the corresponding link of the exit port；It can be first
Select to be used as by the physical port of CB equipment local the exit port of unicast message；If the physical port institute of CB equipment local is right
The link answered is unavailable, can select outlet of the physical port in other CB equipment in the sub- aggregation group as unicast message
