The link connecting from ASR 9k to 7600 is going to udld error-disable state after connecting few seconds..The physical fiber is fine and we tested the same fiber from another ASR 9k too 7600.

Hi

Could you please share the configuration of both ports and show ip interface brief.

Are you using the same SFP model? or have you try with other SFP?

Hi 

I am using sfp-10g-lr on asr and x2-10g-lr on 7600 side and I tried with different SFPs and X2s.

Configuration is default on ASR side and this is the configuration on 7600 side.

interface te1/5
