Hello Mohan,

if you want to limit to 1 Mbps all traffic that goes from each branch router to the central site you need to use traffic shaping.


you can take advantage of Class Based Traffic Shaping:


http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/reg_pkt_flow_per_cls_ps6350_TSD_Products_Configuration_Guide_Chapter.html


policy-map shape-1mbps

class default

shape average 1000000


! to call a child policy

service-policy policy_child


you can also implement a two level QoS by calling a CBWFQ child policy so that you emulate a pipe of 1 Mbps and you also provide differianted QoS to different traffic classes


see


if you like you can adjust the bandwidth parameter to 1 Mbps and EIGRP will use by default up to 50% of the stated BW for its updates


Hope to help

Giuseppe
