AshvinO,
What you are asking me to do is not possible on the EX4500. The only way to create a routable interface is to create a routed VLAN interface (RVI) which is a logical interface associated with the VLAN rather than any physical port specifically. This is not a Layer 3 switch with routed port capabilities (like the Cisco Nexus 7000).
The fact that the ASR2 connection, with identical optical hardware is now working while the ASR1 connection (and incidentally other ports on both routers) are still not working equally puzzles me.
