class test_ip6.TestIPv6(methodName='runTest')

Bases: framework.VppTestCase

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, packet_sizes)

Create input packet stream for defined interface.

Parameters:

• src_if (VppInterface) – Interface to create packet stream for.
• packet_sizes (list) – Required packet sizes.

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.
• pg_if_packet_sizes (list) – packet sizes 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.

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.
