| Configure IPv6 forwarding in 3-node circular topology
| | [Documentation]
| | ... | Set UP state on VPP interfaces in path on nodes in 3-node circular
| | ... | topology. Get the interface MAC addresses and setup ARP on all VPP
| | ... | interfaces. Setup IPv6 addresses with /64 prefix on DUT-TG links.
| | ... | Configure IPv6 adresses with /96 prefix on DUT1-DUT2 link and set
| | ... | routing on both DUT nodes with prefix /64 and next hop of neighbour
| | ... | DUT interface IPv6 address. Configure route entries for remote hosts
| | ... | IPv6 addresses if required.
| | ...
| | ... | *Arguments:*
| | ... | - tg_if1_ip6 - IPv6 address of TG interface1. Type: string
| | ... | - tg_if2_ip6 - IPv6 address of TG interface2. Type: string
| | ... | - dut1_if1_ip6 - IPv6 address of DUT1 interface1. Type: string
