If we carefully see the given network, there is a direct current path from C-D-E-F as shown in figure.
 
Hence if current enters at A and exit at B, then the entire current will flow through only two resistances R1 and R2 as shown in left side figure.
 
Hence as shown in right side of figure, resistance across A and B is 2R Ω .
