Hi Group,
I have a problem with this task 2.5 on Vol2 Section 13. The task requires to configure fallback bridging between vlan999 and vlan1000. As soon as I configure the bridge group, I get the following error: 01:02:06: %SW_MATM-4-MACFLAP_NOTIF: Host 0013.194a.5618 in bridge group 1 is flapping between port Po1 (Vl999) and port Po1 (Vl1000) Cat3550-1(config-if)# 01:02:20: %SW_MATM-4-MACFLAP_NOTIF: Host 0013.194a.5618 in bridge group 1 is flapping between port Po1 (Vl1000) and port Po1 (Vl999) The mac address 0013.194a.5618, which is an address of the SW2 switch, is flapping between the two SVIs. Somehow I do not understand that why this mac is flapping.... Any ideas? Many thanks in advance Roger
