Question 132

The following about the Router-LSA of OSPFv3 is correct?( Single choice questions).

The router-LSA data area contains the Link-Local address

The router-LSA data area contains the Interface ID of the neighbor on this side

Similar to OSPFv2, the Option field exists in the header of LSA, not in the data area of Router-LSA

When LS type= Ox0001 in the head of LSA, the data area representing LSA is Router-LSA

Question 133

When judging the old and new LSA, the serial number parameter and the age parameter are used , and the following two parameters are correct for ?( Multiple choice questions).

When the router receives two LSAs, where the sequence number is the same and the checksum is the same, the smaller the age, the better

When the router receivesóThe age of the LSA is set to 3600S, the LSA is unavailable

If the serial number of the LSA reaches the end value of Ox7FFFFFFF, the current router advertises an LSA with an age of 3600S

Both the serial number and age parameters can determine whether the LSA is old or new, and the router prioritizes the sequence to participate in the teaching, and the larger the better

The following description of MP-BGP is incorrect?( Single choice questions).

The MP_UNREACH_NLRl of the update message, excluding the path nationality.

MP-BGP can be used to assign tags.

MP_REACH_NLRI and MP_UNREACIH_NLRI are optional transition properties.

A complete MP_REACH_NLRI attribute structure contains address family, next hop, and prefix information.

Question 137

The following description of the BGP route reflector is ?( Multiple choice questions).

Cluster_List is an optional non-staging property for ring protection within the cluster.

The route learned from the client, all non-clients and clients published to this RR.

A network of bones is divided into multiple reflection clusters, each of which configures the other RRs as non-clients, and establishes an IBGP full connection between the RRs.

The Originator_ID attribute is generated by the Route Reflector (RR) for inter-cluster ring protection.

Question 138

The router connects two EBGP neighbors through two parallel Serial cables, what do you do to achieve bidirectional negative sharing between two EBGP neighbors connected by these two parallel Serial cables? ( Single choice questions).

Without any method, BGP automatically implements load sharing of traffic across different autonomous systems on the available links

Use the Loopback interface to establish an EBGP neighbor relationship, configure EBGP Muti-hop, configure the Loopback interface as the update source, and then use IGP to implement Equivalent path load sharing between Loopback addresses

Configure the EBGP neighbor relationship with the Loopback interface as the update source, and the IGP in each AS needs to introduce two equivalent paths to the loopback address of the EBGP neighbor; And you need to use the command "next-hop?local"

Use the command "ebgp-load-balance" at both ends

To configure an EBGP neighbor relationship with the Loopback interface as the update source, the IGP in each AS needs to introduce two equivalent paths to the EBGP neighbor loopback address ; And the commands "ebgp maxhop" and "next-hop-local" are used
