RT-5.8: IPv6 Link Local

Summary

Configure an IPv6 address which is in link local scope. Verify the link local IPv6 address exists by checking the state path.

Procedure

  • Subtest #1 - Configure IPv6 link local

    • Configure DUT port 1 and OTG port 1 with an IPv6 link local scope IP address
    • Configure DUT port 2 and OTG port 2 with an IPv6 link local scope IP address
    • Validate config and state paths are set

  • Subtest #2 - Verify the interface will pass IPv6 traffic as expected

    • Send IPv6 traffic from OTG port 1 to OTG port 2, validate OTG port 2 does not receive the traffic
    • Send IPv6 traffic from OTG port 1 to DUT port 1, validate DUT port 1 receives the traffic

  • Subtest #3 - Verify adding and removing global unicast address does not affect link local address

    • Add configuration for a global unicast address on DUT port 1 and DUT port 2
    • Validate config and state paths are set
    • Send IPv6 traffic from OTG port 1 to OTG port 2, validate OTG port 2 receives the traffic
    • Remove configuration for the global unitcast address on DUT port 1
    • Validate that DUT port 1 link local address is still configured
    • Send IPv6 traffic from OTG port 1 to DUT port 1, validate DUT port 1 receives the traffic
    • Send IPv6 traffic from OTG port 1 to OTG port 2, validate OTG port 2 does not receive the traffic

  • Subtest #4 - Verify enable/disable of DUT port 1 does not affect link local address

    • Disable/enable the port and see if the configured link-local address stays?
    • Validate that DUT port 1 link local address config and state paths continue to contain the address assignment
    • Send IPv6 traffic from OTG port 1 to DUT port 1, validate DUT port 1 receives the traffic
