There are unidirectional ports within the NML topology that are identified as connected to remote networks, however, the vlan ranges associated with them do not match.
I think this is perfectly valid topology.
An example of this is one of the links between Netherlight and UvA:
urn:ogf:network:netherlight.net:2013:port:a-gole:testbed:uva:1:in 1779-1799
urn:ogf:network:uvalight.net:2013:uvalight-netherlight 1780-1783
It could be that one end was a router (with high flexibility for VLAN assignment), and the other end a switch where VLANs are a global resources, and hence some of them occupied. We have to consider that at some point these might be automatically generated.
Obviously, I only have four STP's in each network that can form SDP between the networks, however, do the remaining 16 STP in Netherlight exist since nothing can ever utilize them? At the moment I toss these 16 potential STP on the floor since they provide no value, however, I wouldn't want to violate any unspoken rules ;-)
I think this behavior is correct, do the union of the two labels sets for demarcations (which is equivalent to dropping them, just another abstraction). Best regards, Henrik Henrik Thostrup Jensen <htj at nordu.net> Software Developer, NORDUnet
