Ospfv3AsExternalLsaBlock Writable Attributes

Attribute

Description

AdminTag

Administrative tag.

Type: u32

Default: 0

AdvertisingRouterId

Specifies the simulated router that will advertise Prefix LSAs.

Type: ip

Default: null

Age

Initial value of LS Age in an LSA header.

Type: u16

Default: 0

Range: 0 - 3600

CheckSum

Specifies the LSA will be advertised with a good or a bad checksum. A bad checksum indicates a corrupted LSA and is used for negative testing.

Type: enum

Default: GOOD

Possible Values:

Value	Description
BAD	LSA will be advertised with a bad checksum.
GOOD	LSA will be advertised with a good checksum.

ExtendedLsaSubTlvs

Select one or more sub-TLVs to include, e.g. IPv6 Forwarding Address sub-TLV, IPv4 Forwarding Address sub-TLV or Route-Tag sub-TLV.

Type: enum

Default: 0

Possible Values:

Value	Description
IPV6_FORWARDING_ADDR	IPv6 Forwarding Address sub-TLV.
IPV4_FORWARDING_ADDR	IPv4 Forwarding Address sub-TLV.
ROUTE_TAG	Route-Tag sub-TLV.

ExtendedLsaTlvs

Select the TLV to include, e.g. IPv6 External Prefix TLV.

Type: enum

Default: IPV6_EXTERNAL_PREFIX

Possible Values:

Value	Description
IPV6_EXTERNAL_PREFIX	IPv6 External Prefix TLV.

ForwardingAddr

IPv6 address. If this is included, all data traffic to the advertised routes will be forwarded to this address.

Type: ipv6

Default: null

Ipv4ForwardingAddr

The IPv4 address which all data traffic to the advertised LSAs will be forwarded to

Type: ip

Default: 0.0.0.0

LinkStateId

LSA identifier, chosen arbitrarily by the advertising router.

Type: u32

Default: 0

LsType

Type of LSA advertised.

Type: enum

Default: NONE

Possible Values:

Value	Description
NONE	None.
ROUTER_LSA	Router LSA.
NETWORK_LSA	Network LSA.
INTER_AREA_PREFIX_LSA	Inter Area Prefix LSA.
INTER_AREA_ROUTER_LSA	Inter Area Router LSA.
AS_EXT_LSA	As External LSA.
NSSA_LSA	NSSA LSA.
LINK_LSA	Link LSA.
INTRA_AREA_PREFIX_LSA	Intra Area Prefix LSA.
ROUTER_INFO_OPAQUE_LSA	Router Information LSA.
SRV6_LOCATOR_LSA	SRv6 Locator LSA.

Metric

Cost of the advertised route.

Type: u32

Default: 1

Range: 1 - 16777215

MetricType

Indicates whether the route's cost should be included in the SPF calculation.

Type: bool

Default: FALSE

Possible Values:

Value	Description
TRUE	Metric is considered larger than any intra-AS path.
FALSE	Metric is expressed in the same units as interface cost.

PrefixOptions

This is a bit mask that describes the capabilities of the advertised prefix. The prefix options you set with this attribute will be used for every prefix in the LSA.

See RFC 2740 for more information.

Type: enum

Default: 0

Possible Values:

Value	Description
NUBIT	NU (NU, Bit 1) - No Unicast capability bit. If set, the prefix is excluded from IPv6 unicast calculations.
LABIT	LA (LA, Bit 0) - Local Address capability bit. If set, the prefix becomes an IPv6 interface address of the advertising router.
MCBIT	Multicast (MC, Bit 2) - Multicast capability bit. If set, the prefix is included in the IPv6 multicast calculations.
PBIT	NSSA (N/P, 3) - The "P" bit or "Propagate" bit. Set this on the NSSA area prefixes that should be readvertised at the NSSA border.
DNBIT	Downward (DN-bit,3)
NBIT	Node (N-bit,2)
ELCBIT	Entropy Label Capability (E-flag,1)
ACBIT	Anycast (AC-bit,0)

RefLinkStateId

Specifies the LS ID of LSA that carries additional information for the advertised route.

Type: u32

Default: 0

RefLsType

Specifies the type of referenced LSA.

Type: u16

Default: 0

Range: 0 - 0xffff

RouteCategory

Specify the route type.

Type: enum

Default: UNDEFINED

Possible Values:

Value	Description
UNDEFINED	Category not defined. The default category assigned to a manually created block.
PRIMARY	Primary - a preferred route that has duplicates (secondary routes) advertised by other ports.
SECONDARY	Secondary - a less preferred backup route.
UNIQUE	Unique - indicates that a single port in the test configuration advertises this route.
ANY	Any route.

SeqNum

Initial value of the LS Sequence Number in an LSA header.

Type: u32

Default: 0x80000001

Range: 0 - 0xffffffff
