Comprehensive and Detailed In-Depth Explanation:

In theCloudCampus public cloud scenario, when devices are deployed through theHuawei registration query center, there isno need to configure DHCP Option 148on the campus network’s DHCP server.

Theregistration query centerautomatically provides thecontroller IP addressto the devices during the registration process.

DHCP Option 148is typically used to provide theiMaster NCE-Campus addressin on-premises or private cloud scenarios.

In thepublic cloud scenario, the devices obtain this information directly from the Huawei cloud platform, makingOption 148 unnecessary.

The IP prefix list configuration:

ip ip-prefix TEST permit 10.0.0.0 24 less-equal 30

10.0.0.0/24: Matches because it falls within the10.0.0.0/24prefix with thesame prefix length (24).

10.0.1.0/24: Matches because it also falls within the/24network range.

10.0.2.0/24: Matches for the same reason as the above.

10.0.0.1/30: Matches because it falls within the/24 prefixand itssubnet length (30)is within theless-equal 30range.

The prefix list permits any route that falls within the10.0.0.0/24network with asubnet mask ranging from /24 to /30. Therefore,all given routes are matched.

Intra-Area-Prefix-LSA (Type 9) is used in OSPFv3 to carry IPv6 prefix information for a router or network and is flooded within the area.

Link-LSA (Type 8) is only sent on the local link and is not flooded throughout the area.

Inter-Area-Prefix-LSA (Type 3) and Inter-Area-Router-LSA (Type 4) are also flooded within an area but originate from ABRs, typically for cross-area route advertisement.

That said, Intra-Area-Prefix-LSA is specifically flooded within an area, matching the context of the question directly.

Exact Extract - Huawei HCIE-Datacom OSPFv3 Module:

“Intra-Area-Prefix-LSAs are flooded within the area and advertise the IPv6 prefixes associated with router and network LSAs.”
