mDNS (Bonjour) between VLANs

[spgsitsupport]

All routing is done by HPE 5900

BYOD VLAN 120
AV Devs VLAN 22

With ACL I can make devices in VLAN 120 access devices in VLAN 22, but of course no mDNS

Does Comware support mDNS gateway (as it is in ArubaOS I believe)?

Is there any other way to route Bonjour traffic (so BYOD devices can fin/access Apple device in VLAN 22) ie VM?

There is simmilar question 4 years old with zero replies!

Thanks

Hi @spgsitsupport !

mDNS uses reserved IPv4 multicast range address 224.0.0.251 that is not intended to be routed between L3 interfaces, so PIM won't help in this case. Different vendors implement different approaches to route mDNS traffic, the most common is mDNS gateway or relay. However, this feature has not been implemented in 5900.

Seriously a pity

Had to revert to using Ubuntu 20 Server with Avahi Reflector VM, connected to 5 separate networks that I want to be able to access various Air* services

Harly ideal, but works
