Could this be a stable solution to have same L2 domain but two DHCP Servers one in site R1 and one in site R2?Use DHCP snooping on both bridges! I use xx.xxx.xxx.1 ip address for R1 with dhcp pool 10-130, and xx.xxx.xxx.254 ip address for R2 and dhcp pool 131-240.
because I with rb951g with ros 6.33rc22 not have WPS button?RouterOS does have a WPS button in the QuickSet page. PIN mode is not supported, since it is not very secure, but Button mode we do have
and then? What can I do?Because of cached dns records. Probably.
yes!Use you the default settings from the routerboard?
and you know how?Yes, this is the best way to do.
