In order to ensure the reliability of message delivery, all sending and receiving of LDP messages must be based on TCP connections.

TRUE

FALSE

Type1 LSA

Type3 LSA

Type7 LSA

Type5 LSA

QUESTION 113
A campus has deployed IPv6 for service testing. There are 4 routers in the network, running 0SPFv3 to implement IPv6 network interconnection. As shown in the figure, an engineer checked the LSDB of R2 and intercepted one of the Link-LSAs. Which of the following statements is true about the description of this LSA?

The router that generates this LSA is R2 port R2 connected

IPv6 address prefix for GEO/0/0: 2001:DB8:2345:23::/64

The link-local address of R2 interface GEO/0/0 is: FE80::2E0:FCFF:FEC, D:4F79

The SA shows 2 does not support external routing, but participates in IPv6 routing calculation

QUESTION 114
In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.
label, the description of the two-layer label in the following options is wrong

MPLS VPNThe outer label is made byLDPprotocol or statically assigned, the inner label is assigned by the correct end MP-BGPassigned by neighbors

MPLS VPNEThe outer layer label is called the private network label, and the inner layer label is called the public network label

By default, the outer label is singled out before the packet is forwarded to the last hop device

Layer labels are used inPEThe device sends the packet correctly to the correspondingVPNmiddle
