Which of the following statements about the OSPFV3 packet format is correct?

Network administrator A wants to use the AS-Path Fiter to match the routing entries of the BGP routing attribute AS_PATH [100 200 300]. Network administrator A sorts out the four configurations in the figure. Which of the following configurations can satisfy network administrator A's requirements? Require?

As shown in the figure, 0SPF is enabled on all interfaces of the router. The cost value of the link is marked in the figure, R2's

LoogbackO is advertised by mouth in area 0, then in In area 1, both R2 and R3 transmit the routing information of 10.0.2.2/32 in the form of Typae3 LSA.

Since BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors.

The routing policy deployed between IBGP neighbors is invalid.

In the VLAN aggregation technology, multiple Sub-VLANs are used to isolate wide-open domains, and these Sub-VLANs are aggregated.

Synthesizing a logical Super-VLAN, a company divides different departments into different Sub-VLANs, because

Sub-VL AN not only includes physical connection, but also can establish three-layer VLAN ANIF interface, which can directly carry out three-layer communication with external network.

BGP4+ carries the next hop address of the IPv6 route through the Next Hop attribute in the Update packet. (Moved into Attribute 14)

The ipv6 enable topology standard has been set in the S-IS protocol view. The meaning of this command is:

Pv4 shares a topology with IPv6.

When B, CPIMPLS TP VPN is deployeD. the OSPF VPN Route Tag (VPN Route Tag) is not transmitted in the extended community attribute of MP-BGP, but the local concept is only meaningful on PE routers that receive MP-BGP routes and generate OSPF LSAs.

To ensure security, authentication can be configured in the OSPFV3 process area view.
