Question 31
IS-IS is a link-state routing protocol that uses the SPF algorithm for route calculation. As shown in the figure, a campus deploys both IPv4 and IPv6 and runs IS-IS to achieve network interconnection. R2 only supports IPv4. Which of the following statements is true about the topology calculation of this network?
If you want IPv4 and IPv6 network computation to form the same shortest path tree, you need to run the ipv6 enable topology ipv6 command to enable the IPv6 capability in the IS-IS process.
By default, since R2 does not support IPv6, in the shortest path tree formed by IPv6 network calculation, the path from R1 to R4 is: R1-R3-R4
By default, IPv4 and IPv6 networks will be calculated separately to form different shortest path trees
By default, in the shortest path tree formed by IPv6 network calculation, the path from R1 to R4 is: R1-R2-R4. Since R2 does not support IPv6, R2 will directly discard IPv6 packets after receiving them, causing traffic loss.
Question 32
Please match 0SPFv3LSA with its transmission range.
AS-external-LSA Autonomous system-wide intra-regional propagation
Network-1SA intra-regional spread
Link LsA local link range
Question 33
The following description of TL in PLSHeader is correct:
Limit the LSR
Control of upstream equipment for label distribution
Similar to the TTL in the IP header, it is used to prevent packet loops
To control label distribution
Question 34
In PLSVPN, in order to distinguish IPv4 prefixes that use the same address space, the value of R0 is added to the IPv4 address. The correct description of the following options is:
On a PE device, each VP instance corresponds to a value of 0. On the same PE device, the RD value must be unique.____, ____, ____.
RD can be used to control the publication of 1 routing information
RD is encapsulated in Update message as BGP extended community attribute during delivery
After the PE receives the IPv4 route from the CE, it adds RD to the IPv4 route to convert it into a globally unique VPN-IPv4 route, and publishes it on the public network
Question 35
As shown in the figure, there is a packet containing a three-layer label header. Please select the values (decimal) corresponding to the x, and Z fields in the figure.
YZX
Question 36
As shown in the figure, R1, R2, R3, and R4 are in the same PLs domain, and LDP is used to distribute IPLS labels between devices. R4 is the Egress LSR of the FEC 4.4.4.0/24. If you want to achieve R1 access
4.4.4.0/24, R4 does not need to query the label table but can know the forwarding priority of the data, then the outgoing label of R3 for the FEC should be:____. (Please fill in the Arabic numerals directly, without symbols)
(0)
Question 37
About the difference between NSR and NSF, which is correct?
NSP can be done without neighbor routers
NSF must rely on neighbor routers to complete
Both NSR and NSP require neighbor routers to complete
NSR must rely on neighbor routers to complete
Question 38
The RR rules for advertising routes violate the IBGP split horizon rules, which may cause loops in the AS. Which routing attributes does RR use to prevent loops?
Cluster List k
Nexthop
AS-PATH
Originator ID
Question 39
Network administrator A wants to use AS-Path Filter to match the BGP routing attribute AS_PATH[100200300]. Network administrator A sorts out the four configurations in the figure. Which of the following configurations can meet the requirements of network administrator A?
way A
way D
WayC
way B
Question 40
As shown in the figure, on the R1 router, the network administrator can control the path of the traffic entering AS100 after modifying the value of the routing entry sent to R2 through the routing policy.
Yes
wrong
