(2)configure bridge and port
...
Then ge-1/1/2 will transmit the packets with vlan 200,src mac is 88:88:88:00:00:00,ge-1/1/3 will transmit the packets is src mac is 44:44:44:00:00:00,vlan is 300
Example 2: IPv4 Multicast (l2 multicast)
(1)enable TTP and add bridge and port first.
...
Then ge-1/1/2 will transmit the packets which are the sane with the packets from ge-1/1/1.
Example 3: IPv6 Multicast(l3 multicast)
(1) enable TTP and add port and bridge.
(2)add group
