Re: [Teas] Connectivity matrix in draft-ietf-teas-yang-te-topo

Hi,

Another item that can be considered is to add a Label (Following RFC7579)
restrictions. This is needed, for example,  in case of Fixed muxponders,
where the connectivity between the Low order ODUs to the high-order ODU is
fixed on each end.

Can it be added to the list of changes for the connectivity matrix?

Thanks,
Cyril
