(also please don't hesitate to remind me each time there is a Hack'n'ACK around the corner ;-)) |
|
So, the default behavior stays the same for a 6lbr but we can configure it to be non-authorative with this patch, right? |
|
Yes that's the idea. |

There was a problem hiding this comment.
Maybe you can add a line to the docs of the border router (or border router example?) about how to possibility to make a 6lbr non-authorative.

Contribution description
Currently all nodes compiled with
gnrc_sixlowpan_border_router_defaultwill act as an authoritative border router by default.We have a setup with many wireless nodes that are all potential (authoritative) border routers (see #21080), but only one of them will be selected (at run-time) to do so.
This adds a
NETOPT_6LO_ABRthat can be used to enable / disable the authoritative border router functionality on an interface as well as aCONFIG_GNRC_IPV6_NIB_ABRto control the start-up default.Testing procedure
