I am wondering, can HWMP+ mesh share an interface with non-mesh traffic.

example.

RB1200 at tower site, RB411 ethernet attached to RB1200 ether1, RB411 has sector and clients connect via nv2 & station WDS mode, RB411's ether1 & wlan1 bridged in bridge1.

RB1200 10.0.0.1
RB411 bridge1 10.0.0.2
clients 10.0.0.10-100

Can I put the RB1200's ether1 into a new mesh1, and still reach 10.0.0.2 and the clients via ether1 or does the mesh interface take over the ports that are members of it?

no one doing this huh?
