8.2.17. VRF Routed-Forwarding

8.2.17.1. eth2p-ethip4-ip4basevrf-func

Vpn routed forwarding - baseline IPv4

  • [Top] Network Topologies: TG=DUT1=DUT2=TG 3-node topology with two links in between nodes.
  • [Enc] Packet Encapsulations: Eth-IPv4-ICMPv4 for L2 switching of IPv4.
  • [Cfg] DUT configuration: Each DUT is configured with two VRF tables; Separation of traffic is tested by IP packets; Basic ARP and ROUTES are set on DUT nodes; IP addresses are set on DUT interfaces.
  • [Ver] TG verification: Test ICMPv4 Echo Request packets are sent by TG on link to DUT1, DUT2 or back to TG; On receipt TG verifies packets for correctness and their IPv4 src-addr, dst-addr, and MAC addresses.
  • [Ref] Applicable standard specifications:
