We are currently using 3750's (non-E series)in the distribution layer 3 going to the access layer 2. We have noticed a lot of retrans issue on the access layer 2, 3750's, but no retrans in the same IP address range on the distribution layer 3, 3750's. The link between access and distribution are redundant dot1q trunks meshed. The issue still happens without the redundant meshed environment. Currently at 12.1(19). Has anyone else experienced this retrans issue and what was done to solve it.
