| Initialize IPv4 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 IPv4 addresses with /30 prefix on DUT-TG links
| | ... | and set routing with prefix /30. In case of 3-node set IPv4 adresses
| | ... | with /30 prefix on VLAN and set routing on both DUT nodes with prefix
| | ... | /30. Set next hop of neighbour DUT interface IPv4 address. All
| | ... | interfaces are brought up.
| |
| | ... | *Arguments:*
| | ... | - tg_if1_net - TG interface 1 IP subnet used by traffic generator.
| | ... | Type: integer
| | ... | - tg_if2_net - TG interface 2 IP 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:
| | ... | - dut1 - DUT1 node.
| | ... | - dut2 - DUT2 node.
| | ... | - dut1_if2 - DUT1 interface towards DUT2.
