| # 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. |
