Looks more you Are searching for OSPFAn example, the 5 GHz. loses its connection through DFS.
The 2.4 GHz. connection must take over immediately.
That is why I would put the two interfaces in bonding.
Ether1 = 5 GHz. link
Ether2 = 2.4 GHz. link
Can also add a device each side of the wireless devices then use RSTP
WL2---2GHz L2-----WL2 / \ ---RB1(With RSTP) RB2(With RSTP)----- \ / WL1----5GHz L2-----WL1
To be honest, I dont know, never looked into it, according to Mikrotik, it seems possible, i.e. if bridged in Stations-WDS mode you can use RSTP, etc, so I suppose it will depend on how you did the wireless configwill a wireless bridge pass the xSTP related frames?Can also add a device each side of the wireless devices then use RSTP
