VPLS Tagged Mode
The examples show the minimum configuration required for enabling a VPLS Mesh peer between PE1, PE2, and PE3 in Tagged Mode. In the below example PE1 and PE2 uses VLAN 10 for binding the VPLS instance to the attachment circuit and PE3 used VLAN 20 where it shows that VLAN swapping is supported.

VPLS Split Horizon Group
In VPLS Hierarchy, multiple attachment circuits (AC) can be configured per few VPLS instances and AC-AC traffic blocking is not supported.Thus,when the PE router receives a broadcast, multicast, or unknown unicast packet on an AC.It sends the packet out on all other attachment circuits to all other CE devices participating in that VPLS instance.
To avoid this problem of a packet looping in the provider core, the PE devices enforce a "split-horizon" principle for the VPLS instances. That means the traffic will not flood if AC1 and AC2 are in same split horizon group.
The examples show the minimum configuration required for enabling a VPLS Mesh peer between PE-1, PE-2 with split horizon group. In the below example PE-1 and PE-2 uses split horizon groups where traffic can't be forwarded between the ACs if they are part of same access groups.But can send/receive from network ports.
