Link state ID: ID of the router that originated the LSA.
•
V (Virtual Link): Set to 1 if the router that originated the LSA is a virtual link endpoint.
•
E (External): Set to 1 if the router that originated the LSA is an ASBR.
•
B (Border): Set to 1 if the router that originated the LSA is an ABR.
•
• # Links: Number of router links (interfaces) to the area, as described in the LSA.
Link ID: Determined by link type.
•
Link data: Determined by link type.
•
Type: Link type. A value of 1 indicates a point-to-point link to a remote router; a value of 2 indicates
•
a link to a transit network; a value of 3 indicates a link to a stub network; and a value of 4 indicates
a virtual link.
#TOS: Number of different TOS metrics given for this link. If no TOS metric is given for the link, this

field is set to 0. TOS is not supported in RFC 2328. The #TOS field is reserved for early versions of
OSPF.
