Acee:

 

As long as draft-ietf-idr-bgp-prefix-sid indicates how to handle the
duplicates then it is not a malformed attribute or a conflict between
attributes.

 

The WG needs to still discuss the attribute discard case for the SR routing
case.  I've started another thread for that discussion on "Does SRGB TLV in
draft-ietf-idr-bgp-prefix-sid qualify for BGP Attribute discard?"

PS - I believe that your suggested text you sent me as shepherd handles
duplicates.  Perhaps you can ask the WG to review it to see if I am correct.

If the application also receives a conflicting value of SRGB from BGP via
the SRGB TLV in the Prefix SID Attribute then this could be logged as an
error but I am not sure we want to discard the entire BGP Prefix SID
attribute in this case. 


The attribute is not malformed in this case, so there would be no reason to
apply the attribute-discard procedure.

 

FWIW, I agree totally.
