+| Initialize IPv6 forwarding with VLAN dot1q sub-interfaces in circular topology
+| | [Documentation]
+| | ... | Set UP state on VPP interfaces in path on nodes in 2-node / 3-node
+| | ... | circular topology. In case of 3-node topology create VLAN
+| | ... | sub-interfaces between DUTs. In case of 2-node topology create VLAN
+| | ... | sub-interface on dut1-if2 interface. Get the interface MAC addresses
+| | ... | and setup ARPs. Setup IPv6 addresses with /64 prefix on DUT-TG links
+| | ... | and set routing with prefix /64. In case of 3-node set IPv6 adresses
+| | ... | with /64 prefix on VLAN and set routing on both DUT nodes with prefix
+| | ... | /64. Set next hop of neighbour DUT interface IPv6 address. All
+| | ... | interfaces are brought up.

+| | ... | *Arguments:*
+| | ... | - tg_if1_net - TG interface 1 IPv6 subnet used by traffic generator.
+| | ... | Type: integer
+| | ... | - tg_if2_net - TG interface 2 IPv6 subnet used by traffic generator.
+| | ... | Type: integer
+| | ... | - subid - ID of the sub-interface to be created. Type: string
+| | ... | - tag_rewrite - Method of tag rewrite. Type: string
+| |
+| | ... | _NOTE:_ This KW uses following test case variables:
