[c-nsp] ip nbar

dears

i have some wimax base station connected to Cisco ME6524 
now the customers when connected a GRE tunnel is established between the RAS and the ASN GW
now the ip route cache flow is not supported on the switch 
now regarding the GRE tunnel can i use the nbar protocol to manipulate the traffic or it will not be useful coz of the GRE tunnel ?
and does the GRE tunnel protects from the broadcast ?
