Delays are calculated outbounds towards destination so
u have 2 choices either change on R2 serial interface
connected to r5 if r2 is multipoint then it will not
make any difference it will change for r5 and r6 , R5
serial is not outbound to destination , changing the
ethernet will take effect in ur case.
But Key is Delays are acummulation of outbound
interfcaes from sourec to destination
