According to this example, the Split Horizon group assignments for bridge domain all_three are:
Split Horizon GroupBridge Port/Pseudowire
0bridge port: gig0/0/0/0.99
2bridge port: gig0/0/0/0.101
0PW: 192.168.99.1 pw-id 1
2PW: 192.168.99.9 pw-id 1
1PW: 192.168.99.17 pw-id 1
Blocking Unknown Unicast Flooding: Example
Unknown-unicast flooding can be blocked at these levels:
• bridge domain
• bridge port (attachment circuit (AC))
• access pseudowire (PW)
This example shows how to block unknown-unicast flooding at the bridge domain level:
