Hello Guru of Cisco !!! I have a problem with STP.... I have a switch 3560 and its connected to the core switch by Cisco Aironet 1410 and cisco modem 878. I configured on switches RSTP. But when i open two interfaces in 3560 where connected Aironet and modem there is a loop. I found that Modem 878 which connected to the switch 3560 dot recive bpdu packets from Core. And it made itself as a root. Root must be Core switch. How to configure modem 878 so it will send BPDU packets form core....?

P.S. Thanks !!! My english is not good enough, so excuse me:)... I hope u understand my question
