IPv4 Test Case

config_fib_entries(count)

For each interface add to the FIB table count routes to “10.0.0.1/32” destination with interface’s local address as next-hop address.

Parameters

count (int) – Number of FIB entries.

  • TODO: check if the next-hop address shouldn’t be remote address instead of local address.

create_stream(src_if)

Create input packet stream for defined interface.

Parameters

src_if (VppInterface) – Interface to create packet stream for.

modify_packet(src_if, packet_size, pkt)

Add load, set destination IP and extend packet to required packet size for defined interface.

Parameters

  • src_if (VppInterface) – Interface to create packet for.

  • packet_size (int) – Required packet size.

  • pkt (Scapy) – Packet to be modified.

setUp()

Perform test setup before test case.

Config:
  • create 3 pg interfaces

    • untagged pg0 interface

    • Dot1Q subinterface on pg1

    • Dot1AD subinterface on pg2

  • setup interfaces:

    • put it into UP state

    • set IPv4 addresses

    • resolve neighbor address using ARP

  • configure 200 fib entries

Variables

  • interfaces (list) – pg interfaces and subinterfaces.
