@mrninhvn mdns support on OpenWRT platform is missing, it will be great if you could contribute!

@mrninhvn > I have 2 border routers, 1 running on openwrt and 1 running on raspberry, openwrt border router cannot run alone without the raspberry router. What do you mean...

@caipiblack For why we need a mDNS implementation: 0. The Thread interface doesn't process multicast packets to handle mDNS queries. 1. In Thread network, we use the unicast [SRP](https://datatracker.ietf.org/doc/html/draft-ietf-dnssd-srp-12) protocol...

There is one additional/unexpected PTR record in the DNS update messages: ``` FD10F18847._knx._udp.default.service.arpa: type PTR, class IN, siemens-FD10F18847._knx._udp.default.service.arpa ``` But the only expected PTR record is: ``` _knx._udp.default.service.arpa: type PTR,...

@jinpeng1989 Are you still seeing the same issue?

@jinpeng1989 You can find the subtype format definition in https://www.rfc-editor.org/rfc/rfc6763.html#section-7.1, for your case, the PTR record name should be `FD10F18847._sub._knx._udp.default.service.arpa`. We encourage you to try out the [OT SRP client](https://github.com/openthread/openthread/blob/551602490555033a010ed4b4649821df4b2b882d/include/openthread/srp_client.h)...

re https://github.com/openthread/ot-br-posix/issues/1250#issuecomment-1042986617, @caipiblack how do you build the OTBR? Please provide the feature flags which are enabled. From the log, It looks like the Border Routing feature (`OTBR_BORDER_ROUTING`) is not...

@caipiblack When you run into ping issues from WiFi device to Thread end device, could you capture the traffic on both the WiFi and Thread interface (`wpan0`)?
