    COMMENT:
    ----------------------------------------------------------------------
    
    Alvara, Anton, Michael,
    
    Thank you for the work done for this document.
    
    Just curious about section 3: OSPFv2 routers send their IPv6 address(es) and
    OSPFv3 routers send their IPv4 address(es). But, what happens when OSPFv3
    routers are multi-topology ? Should they also send their IPv6 address(es)? Of
    course, in this case, the issue fixed by your memo does not exist ;-) Probably
    worth mentioning anyway that OSPFv3 multi-topology does not need this feature.

With https://datatracker.ietf.org/doc/rfc5838/, separate instances are required for IPv4 and IPv6 topologies. With this enhancement, you'd only need to advertise TE information in one of those instances. 

Thanks,
Acee
    
    Regards,
    
    -éric
