SLPD multicast support

Hi All:
    I have a management tool to discovery service in a subnet by slp
multicast. But I can't find any openbmc server. I check
https://github.com/openbmc/slpd-lite and find that slpd-lite didn't support
multicast but unicast. I am confused that how to leverage unicast slp in
openbmc? What is the service name in openbmc? Could someone example a slp
usage scenario in openbmc? thanks.

I understand OpenBMC implements Avahi Zeroconf DNS service discovery. 
There is a doc review for it here:
https://gerrit.openbmc-project.xyz/c/openbmc/docs/+/23484

The review points to the implementation which is already merged into the 
project.

Hi Deng,

Yes, Currently openbmc support SLP unicast not multicast.
eg: SLP command for unicast.
slptool -u ${ip} findsrvtypes or findsrvs
If you are really looking for the service discovery, OpenBMC supports Avahi.
eg: avahi-browse -rt _obmc_rest._tcp
