A.Only advertise to IBGP neighbors.

B.properly advertise the route, but do not use the routing to forward data.

C.Discard the route directly.

D.No longer communicate to other BGP routers.

A.Both the serial number and age parameters can determine the old and new LSA, the router will give priority to the sequence to participate in the teaching, the larger the better

B.When the router receives an LSA, the age is set to 3600S, indicating that this LSA is unavailable

C.If the sequence number of the LSA reaches the end value Ox7FFFFFFF, the current router advertises the LSA whose age is 3600S

D.When the router receives two LSAs with the same sequence number and the same checksum, the smaller the age, the better

A.The difference between the configuration of OSPFv2 and OSPFv3 and the C command is that OSPFv2 can use the network command, while OSPFv3 is directly enabled on the interface

B.The difference between the configuration of the stub area and the totally stub area is that the no-summary parameter is configured for the totally stub area

C.There is no need to use router-id command to configure router-id in OSPFv3 configuration, the configuration method is the same as OSPFv2

D.The stub router command is used to configure this router as a stub router. The stub router can form a neighbor relationship with non-stub routers.

A.The user name must be configured under the authenticated interface of CHAP authentication.

B.If the authenticator does not have a username, the password cannot be configured on the authenticated interface.

C.Three-message interactive authentication is required, and the username is transmitted only on the network without transmitting the password.

D.Calculate a hash value using the authentication sequence ID, random number, and key by the MD5 algorithm
