The data link is completely okay. I can access MGMT IPs of routers (10.0.0.2 |10.0.0.4) from 3750 but not from PC. I can access 3750 MGMT IP (10.0.0.1) from PC . Any idea why ?
Note : All management links are in same vlan in 3750

You need the following:
MGMT ETHERNETcables are in
mgmt_vlanon the 3750
mgmt_vlanwith 10.0.0.0 is in the Cisco 3750's global routing table
MGMT ETHERNETGigabitEthernet0 port of the ASR's RP
After you've checked those things, then add this command on each of the ASRs...
ip route vrf Mgmt-intf 0.0.0.0 0.0.0.0 10.0.0.1
