A. If the Ethernet 0/0/0 interface of R1 is down, then R2 will become the master device.

B. If the Ethernet 0/0/0 interface of R3 is down, then R2 will become the master device.

C. If the Ethernet 0/0/1 interface of R1 is down, then R2 will become the master device.

D. If the GE0/0/0 interface of R3 is down, then R2 will become the master device.

A. GigabitEthernct0/0/0 port of Router A belongs to the NSSA area.

B. Router A supports AS-External-LSA flooding

C. Gigabit/thernet0/0/0 port of Router A will participate in IPv6 route calculation.

D. The router is an OSPFv3 device with forwarding capability.

A. True

B. False

A. The multicast network dynamically elects the RP, but the RTA's RPF check on the BSR fails

B. The multicast network is statically configured with RP, but the RTA router is not statically configured with RP

C. The RP elected by RTA is not RTB

D. There is no unicast route from RTB to RTA, causing RTB to fail to check the source RPF

A. Above 1024 is the label space shared by dynamic signaling protocols such as LDP, RSVP-TE, MP-BGP, etc.

B. If the outgoing label value is 0, the router will directly discard the packet

C. 16~1023 is the label space shared by static LSP and static CR-L SP

D. When the penultimate hop LSR performs label switching, if the value of the label after the exchange is found to be 3, the label will be ejected by default and the packet will be sent to the last hop

A. The GR of ISIS notifies the event and maintains the neighbor relationship through the CSNP message.

B. The GR feature of ISIS is enabled by default.

C. The GR of ISIS has a total of four timers.

D. The GR of ISIS defines a new TLV structure to support this feature.

A. True

B. False

A. This router is not configured with authentication, but the neighbor router is configured with authentication.

B. The area ID configured by this router is different from the area ID of its neighbor router.

C. The router's announcement network address does not match the interface mask

D. This router is not configured with an OSPF process ID.

A. stub area is not allowed to inject type7 LSA

B. ASBR cannot exist in the stub area.

C. The virtual link cannot traverse the stub area.

D. The backbone area cannot be configured as a stub area.

A. Duplicate address detection function is realized through RS and RA messages

B. An IPv6 unicast address is called a Tentative Address after it is assigned to an interface and before it passes the duplicate address detection.

C. The interface needs to perform duplicate address detection before enabling any unicast IPv6 address

D. IPv6 duplicate address detection technology is similar to free ARP in IPv4

A. Apply traffic shaping in the direction of the entrance and use traffic policing in the direction of the exit.

B. For traffic shaping, you can adjust the usage of the buffer for traffic exceeding CIR.

C. For traffic shaping, the router will buffer excess packets until the bandwidth is available again.

D. Traffic policing uses the token bucket algorithm, and traffic shaping uses the SPD algorithm.

E. For traffic policing, you can adjust the usage of the cache for traffic exceeding CIR.

A. When sharing a router, each OSPFv3 process runs independently.

B. Multiple instances can be run in the same OSPFv3 process on the same interface.

C. Support multiple instances running on a single link

D. The Instance ID field is included in the OSPFv3 packet header.

A. Peer ignore configured on the peer

B. Active-route-advertise configured on the peer

C. The next hop address of the BGP routing entry is unreachable.

D. The routing entries of the peer BGP routing table are non-optimal.

A. Network layer tail
