| # Adding on-mesh prefix and `config-gateway` command |
| # |
| # - Verifies adding an on-mesh prefix using wpantund/wpanctl `config-gateway` command. |
| # - Verifies prefixes with different flags/priorities added on routers and/or end-devices. |
| # - Verifies `wpantund` adding SLAAC based IPv6 address based on prefix. |
| # - Verified `wpantund` retaining user-added prefixes and adding them back after an NCP reset. |
