I configure the AP205 with stand-alone mode on existing l2 network. So, I need to deploy the Ethernet over GRE function as our customer requires as below.
1. AP connected with L2 network to WMG using EoGRE (Ethernet over GRE) *In case of user traffic not pass-through WLC.
AP-----()____EoGRE____()-----WMG
2. User traffic pass-through WLC *In case of WLC connects EoGRE (Ethernet over GRE)
AP-----WLC-----()____EoGRE____()-----WMG
