- A . TLV 236: describes the reachability of the network by defining routing information prefix, metric value and other information
- B . TLV 232: It is equivalent to the "IP Interface Address" TLV in IPv4, except that the original 32-bit IPv4 address is changed to a 128-bit IPv6 address
- C . When an IPv6 route is advertised externally, the NLPID value must be included
- D . The source IP address of the IS-IS Hello message is changed to the link-local address

- B . Label Forwarding Information Table LFIB
- C . Forwarding Information Table FIB
- D . Routing Information Table RIB
In the network shown in the figure, R1 and R2 establish an EBGP neighbor relationship through a direct interface, and the BFD function is enabled in the BGP process. The BFD parameters are "bfd min-tx-interval 1000 min-rx-interval 1000 detect-multiplier 6". If the IP address of GE0/0/0 on R2 is deleted and the BGP neighbor relationship is checked on R1, which of the following is the longest time for the BGP neighbor relationship on R1 to change from Up to Down?
- A . 0s
- B . 60s
- C . 6s
- D . 180s

- B . 100
- C . 65535
- D . 10
In a BGP/MPLS IP VPN network, VPNv4 routing transfers carry Export RT values. Which of the following path attributes does MP-BGP use to carry Export RT?
- A . AS_Path
- B . Extended_Community
- C . MP_REACH_NLRI
- D . Local_Preference
In a BGP/MPLS IP VPN network, VPNv4 routing transfers carry RD values. Which of the following path attributes does MP-BGP use to carry the RD value?
- A . Extended_Community
- B . AS_Path
- C . MP_REACH_NLR
- D . Local_Preference
When traffic accesses the backbone network, VPN isolation is required. At this time, the interface configuration of a PE router is as follows. If the administrator needs to bind the interface to VPN1 and the interface IP address remains unchanged, which of the following descriptions of the administrator’s operation is correct?
Interface GigabitEthernet 0/0/1
IP address 192.168.100.2 24
- A . After the administrator enters the command ip binding vpn-instance VPN1 in the interface view, it is also necessary to bind the RD value of VPN1
- B . After the administrator types the command ip binding vpn-instance VPN1 in the interface view, he needs to bind the RT value of VPN1.
- C . After the administrator enters the command ip binding vpn-instance VPN1 in the interface view, he needs to reconfigure the interface IP address
- D . The administrator can type the command ip binding vpn-instance VPN1 in the interface view.
