Tomi,
Try putting the serial interfaces in a multilink group and putting
the bridge-group command on the multilink interface. Another option would
be to create a GRE tunnel between the two routers that load balances over
the serial links. Then put the bridge-group command on both the tunnel and
the LAN interfaces.
