Sorry the first e-mail got a little hosed.

Has anybody seen a configs were you have a bridge-group 1 defined on two
differents router. Ethernet interfaces and then share the same vlan
across on ISL trunk on one side to a 5505? Here are the configs. What
happens is once I have issued the bridge-group 1 on the Ethernet
interfaces the trunk link on the 5505 with go from trunk to non-trunk
for about 4-5 seconds and then once it is a trunk link again it will
take about 45-46 seconds then go from trunk to non-trunk and back again.
I am assuming this is some type of spanning tree issue. I have tried
using IEEE for the bridge protocol type and have not seen any changes. I
am link I might need to use Ethernet redundancy techniques instead of my
current configs. Thanks for the help. I have removed most of the
unimportant configs for clarity.
