# Test description: Adding/Removing IPv6 addresses on routers and SEDs on network interface.
|
|
#
|

# Test topology:
|
|
#
|
|
# r1 ---- r2
|
|
# | |
|
|
# | |
|
|
# fed1 sed2
|
|
#
|
|
# IPv6 addresses are added as follows:
|
|
# - On `r2` add `IP6_ADDR_1` with prefix `IP6_PREFIX_1`
|
|
# - On `fed1` add `IP6_ADDR_2` with prefix `IP6_PREFIX_2`
|
|
# - On `sed2` add `IP6_ADDR_3` with prefix `IP6_PREFIX_3`
|
|
#
|
|
# The test then covers the following:
|
|
# - Verify that the addresses are present in "IPv6:AllAddresses" wpantund property on the corresponding node.
|
|
# - Verify that all prefixes are present in network data with correct configuration flags (on all nodes).
|
|
# - Verify that `sed2`'s address is present in `r2` (its parent) "Thread:ChildTable:Addresses".
|
|
# - Verify that addresses/prefixes are retained by wpantund over NCP reset.
|
|
# - Verify that when an IPv6 address is removed from network interface, its corresponding prefix is also removed from
|
|
# all nodes.
