Ayan where are you doing the traceroute from? the switch or a PC connected to the switch?
If from a PC does the traceroute stop at the Extreme switch? If from the Extreme switch can you do a trace route out to a different subnet on the other side of the Cisco router?
From the switch can you ping the cisco router that is directly connected? Remember to add your VR option in the ping so ping vr vr-d
Also can you do a show IPR and show VLAN and paste the output?
Does ping work of u have problems only With trace route ? Check if ipf is enabled Capture icmp and see what's the ttl value switch is sending If config is right u might be hitting a known issue with snmp
