The association between LDP and IGP refers to the suppression of the issuance of reachable routes through IGP. To ensure that the LDP and IGP linkages complete network convergence. Make the IGP and LDP keep the path consistent. Minimize the loss of traffic and improve the reliability of the entire network.
- A . True
- B . False
Regarding the processing mode of MPLS for TTL, which description is correct?
- A . In Pipe mode, when an IP packet passes through the MPLS network, the IP TTL is decremented by 1 to the MPLS TTL field on the ingress node.
- B . The TTL of the MPLS label has the same meaning as the TTL in the IP header, which can prevent the MPLS network from generating a routing loop
- C . Uniform simulation, when the IP packet passes through the MPLS network, the IP TTL of the ingress node is decremented by 1, and the MPLS TTL field is a fixed value.
- D . In MPLS VPN, if you want to hide the structure of the MPLS backbone network, you can use the uniform mode for Ingress packets for private network packets.
In an MPLS VPN network, different CE devices can exchange routing information with the same PE device using different routing protocols. The routing protocols used between different CE devices and the same device are independent of each other.
- A . True
- B . False
Which of the following technologies use tunneling technology to communicate between IPv6 addresses? (Multiple Choice)
- A . Dual Stack
- B . 6to4
- C . ISATAP
- D . NAT64
If the router only needs to forward IPv6 packets, there is no need to configure any IPv4 protocols and addresses on the router.
- A . Ture
- B . False
The following procedure for NDP to resolve the link layer address is correct or not.
- A . Ture
- B . False
BGP 4+ runs between the two routers. The neighbor relationship is normal. However, the BGP routing table of the local router does not have neighbor’s routing entry. What is the possible reason? (Multiple Choice)
- A . The routing entries of the peer BGP routing table are non-optimal.
- B . The next hop address of the BGP routing entry is unreachable.
- C . Peer ignore configured on the peer
- D . Active-route-advertise configured on the peer
Which of the following options may affect the establishment of IBGP neighbors? (Multiple Choice)
- A . Authentication is unsuccessful
- B . The BGP protocol version is inconsistent
- C . IBGP-Multi-hop is not configured
- D . IGP routing is unreachable
Which of the following tools cannot be directly referenced by the If-match clause in the Route-policy?
- A . Regular expression
- B . IP-prefix
- C . AS-path-filter
- D . Community-filt
Which of the following information can be included in a basic network layer packet? (Multiple choice)
- A . Data link layer header
- B . Upper layer data
- C . Network layer header
- D . Path record
- E . Network layer tail
