ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual Table 44. Field LSA Type LS ID Age Sequence Checksum Description The format and function of the link state advertisement. 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-areaprefix 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. 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. The time since the link state advertisement was first originated, in seconds. 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. 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. Chapter 4. Routing | 319

ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual

LSA Type

The format and function of the link state

advertisement. 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-areaprefix 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.
