*** Keywords ***
| Setup VRF on DUT
| | [Documentation]
| | ... | The keyword sets a FIB table on a DUT, assigns two interfaces to it,\
| | ... | adds two ARP items and a route, see example.
| | ...
| | ... | *Arguments*
| | ... | - node - DUT node. Type: dictionary
| | ... | - table - FIB table ID. Type: integer
| | ... | - route_interface - Destination interface to be assigned to FIB.\
| | ... | Type: string
| | ... | - route_gateway_ip - Route gateway IP address. Type: string
| | ... | - route_gateway_mac - Route gateway MAC address. Type string
| | ... | - route_dst_ip - Route destination IP. Type: string
| | ... | - vrf_src_if - Source interface to be assigned to FIB. Type: string
| | ... | - src_if_ip - IP address of the source interface. Type: string
| | ... | - src_if_mac - MAC address of the source interface. Type: string
| | ... | - prefix_len - Prefix length. Type: int
| | ...
| | ... | *Example:*
| | ... | Three-node topology:
| | ... | TG_if1 - DUT1_if1-DUT1_if2 - DUT2_if1-DUT2_if2 - TG_if2
| | ... | Create one VRF on each DUT:
| | ... | \| Setup VRF on DUT \| ${dut1_node} \| ${dut1_fib_table} \
| | ... | \| ${dut1_to_dut2} \| ${dut2_to_dut1_ip4} \| ${dut2_to_dut1_mac} \
| | ... | \| ${tg2_ip4} \| ${dut1_to_tg} \| ${tg1_ip4} \| ${tg_to_dut1_mac} \
| | ... | \| 24 \|
| | ... | \| Setup VRF on DUT \| ${dut2_node} \| ${dut2_fib_table} \
| | ... | \| ${dut2_to_dut1} \| ${dut1_to_dut2_ip4} \| ${dut1_to_dut2_mac} \
| | ... | \| ${tg1_ip4} \| ${dut2_to_tg} \| ${tg2_ip4} \| ${tg_to_dut2_mac} \
| | ... | \| 24 \|
