topic bpdu doesn't cross wireless trunk in Wireless https://community.cisco.com/t5/wireless/bpdu-doesn-t-cross-wireless-trunk/m-p/545372#M87187 <P>I installed 2 bridges 1300 as a backup link. This link carry 5 vlans. Everything works except the spanning-tree. As soon as i establish the radio connection, i get a network loop for these vlans. The ports are in forward state from both switches on each side. Do you know any problem about spanning-tree bpdu crossing wireless link?</P><P></P><P>Thanks</P><P></P><P>Nuno Santos</P> Sun, 04 Jul 2021 19:34:50 GMT nuno.santos 2021-07-04T19:34:50Z bpdu doesn't cross wireless trunk https://community.cisco.com/t5/wireless/bpdu-doesn-t-cross-wireless-trunk/m-p/545372#M87187 <P>I installed 2 bridges 1300 as a backup link.
