IPv6 Test Case

config_fib_entries(count)

For each interface add to the FIB table count routes to “fd02::1/128” 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.

send_and_expect_ra(intf, pkts, remark, dst_ip=None, filter_out_fn=<function is_ipv6_misc>, opt=None)

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 IPv6 addresses
  • resolve neighbor address using NDP

• configure 200 fib entries

Variables:

• interfaces (list) – pg interfaces and subinterfaces.
• flows (dict) – IPv4 packet flows in test.

TODO: Create AD sub interface

classmethod setUpClass()

tearDown()

Run standard test teardown and log show ip6 neighbors.

test_fib()

IPv6 FIB test

Test scenario:

• Create IPv6 stream for pg0 interface
• Create IPv6 tagged streams for pg1’s and pg2’s subinterface.
• Send and verify received packets on each interface.

test_ns()

IPv6 Neighbour Solicitation Exceptions

Test scenario:

• Send an NS Sourced from an address not covered by the link sub-net
• Send an NS to an mcast address the router has not joined
• Send NS for a target address the router does not onn.

Test scenario:

validate_ra(intf, rx, dst_ip=None, mtu=9000, pi_opt=None)

verify_capture(dst_if, capture)

Verify captured input packet stream for defined interface.

Parameters:

• dst_if (VppInterface) – Interface to verify captured packet stream for.
• capture (list) – Captured packet stream.
