Output Field What It Displays...
Link Id Number that uniquely identifies an LSA that a router originates
from all other self originated LSAs of the same LS type.
Advertising Router The Advertising Router. Is a 32 bit dotted decimal number
representing the LSDB interface.
LS Age Number representing the age of the link state advertisement in
seconds.
LS Type The format and function of the specified LSA.
LS Seq Number Number that represents which LSA is more recent.
Checksum Total number LSA checksum.
Lenght Size of the LSA in bytes.
Options Option bits in LSA header. Refer to section A.2 in RFC 2740 for
more information. Possible values are:
V6 — indicates status of V6 bit. If this bit is clear, the router/link
should be excluded from IPv6 routing calculations.
E — indicates status of E-bit. This bit describes the way AS-
external-LSAs are flooded.
M — indicates the status of MC-bit. This bit describes whether IP
multicast datagrams are forwarded.
N — indicates the status of N-bit. This bit describes the handling
of Type-7 LSAs.
R — indicates the status of R-bit. This bit (the `Router' bit)
indicates whether the originator is an active router.
D — indicates the status of DC-bit. This bit describes the router's
handling of demand circuits.
Metric Type Whether the route specified is external type 1 or external type 2.
Metric The cost of using the specified router link.
