EoMPLS in XR

 

Hi there ,

 I am pretty new in XR IOS , and having a doubt in L2MPLS configurations.

 

 : in XR IOS , we need to provide "rewrite ingress tag pop 1/2 symm "commands to pop out the tags . But in Cisco IOS l2MPLS configurations we dont need to pop out the tags. Any specific reasons for this .

Kindly correct me if m wrong.

 

 

Best Regards,

Ram

Hi Ragu,      Are we talking

Hi Ragu,

 

     Are we talking about EoMPLS? This should be the same as in regular IOS, if you are stripping the VLANs you should use rewrite, if you're not or only sending the ethernet frame there's no need for it.
