LSA Type The format and function of the link state
advertisement. LSA Type is one of the following:
• Router LSA — A router may originate one or
more router-lsas for a given area. Each
router-lsa originated in an area describes the
collected states of all the router's interfaces to
the area.
• Network LSA — A network lsa is originated for
every link having two or more attached routers,
by the designated router. It lists all the routers
attached to the link.
• Inter-Area Router LSA — This type describes a
prefix external to the area, yet internal to the
autonomous system. It is originated by an Area
Border Router.
• AS-External LSA — This LSA type describes a
path to a prefix external to the autonomous
system and is originated by an Autonomous
System Border Router.
• Link LSA — A router originates a separate
Link-lsa for each attached link. It provides
router's link local address to routers attached to
the link and also inform them of a list of IPv6
prefixes to associate with the link.
• Intra-Area-Prefix LSA — A link's designated
router originates one or more intra-area prefix
lsas to advertise the link's prefixes throughout
the area. A router may originate multiple
intra-area-prefix lsas for a given area to
advertise its own prefixes and those of its
attached stub links.
LS ID The Link State ID identifies the piece of the routing
domain that is being described by the advertisement.
The value of the LS ID depends on the
advertisement's LS type.
Age The time since the link state advertisement was first
originated, in seconds.
Sequence The sequence number field is a signed 32-bit integer.
It is used to detect old and duplicate link state
advertisements. The larger the sequence number,
the more recent the advertisement.
Checksum The checksum is used to detect data corruption of an
advertisement. This corruption can occur while an
advertisement is being flooded, or while it is being
held in a router's memory. This field is the checksum
of the complete contents of the advertisement,
except the LS age field.
