V6-bit
If this bit is clear, the router/link should be excluded from IPv6
routing calculations. See Section 3.8 of this memo.
E-bit
This bit describes the way AS-external-LSAs are flooded, as
described in Sections 3.6, 9.5, 10.8 and 12.1.2 of [Ref1].
MC-bit
This bit describes whether IP multicast datagrams are forwarded
according to the specifications in [Ref7].
N-bit
This bit describes the handling of Type-7 LSAs, as specified in
[Ref8].
R-bit
This bit (the `Router' bit) indicates whether the originator is an
active router. If the router bit is clear routes which transit the
advertising node cannot be computed. Clearing the router bit would
be appropriate for a multi-homed host that wants to participate in
routing, but does not want to forward non-locally addressed
packets.
DC-bit
This bit describes the router's handling of demand circuits, as
specified in [Ref10].
