Thanks

Hi Carl20849, 

 

As per the Official Viptela training documentation this is what they say about that:

 

qos.JPGSo based on this I would say yes, but you can do a simple test with a wireshark capture and two host PCs.

That's right. When user sets a dscp value, that's written to the outer IP header as well; unless a different code point value is mentioned in rewrite policy. Use the rewrite policy to write to outer IP header
