Which of the following descriptions is correct about configuring static LSPs in MPLS networks?

when a certainLSRforEgress LSR, you only need to configureIn Label,The range is16-1023

when a certainLSRforTransit LSR, you need to configureIn LabelandOut labeljn LabelThe range is161023,Out LabelThe range is16~1048575

when a certainLSRforIngress LSR, just configureOut Label,The range is16~1048575

when a certainLSRforEgress LSR, you only need to configureIn Label,The range is16-1023

when a certainLSRforTransit LSR, you need to configureIn LabelandOut labeljn LabelThe range is161023,Out LabelThe range is16~1048575

Regarding the label space of MPLS, the description is wrong:

If the out tag value is0,The router will directly discard the packet

penultimate jumpLSRWhen performing label exchange, if the exchanged label value is found to be3,By default, the label is popped and the message is sent to the last hop

MPLS is called Multi-Protocol Label Switching. Regarding the label description in MPLS, the correct one is:

MPLSThe system has a variety of label publishing protocols, such asLDPis a label publishing agreement

A label is a fixed-length identifier with only local significance, which is used to uniquely identify the group to which a group belongs.FEC

MPLSSupports single-layer labels as well as multi-layer labels

MPLSThe system has a variety of label publishing protocols, such asLDPis a label publishing agreement

Labeled byMIPLSheader of messageBIt has global significance, that is, the label values of all routers cannot be repeated.

Which of the following statements about LDP Label Retention - Free Way is true:

Requires more memory and tab space

Keep all labels distributed by neighbors

Requires more memory and tab space

Keep all labels distributed by neighbors

Only keep labels from next-hop neighbors and discard all labels from next-hop neighbors

Regarding the description of the encapsulation format of labels in MPLS, the correct one is

MPLSThe total length of a single label is4bytes(32bits)

in the labelTTLfields andIPgroupedTTL( Time To Live.,time-to-live) is similar in meaning and also has the effect of preventing loops

The traditional BGP 4 can only manage IPv4 single routing information. In order to provide support for a variety of network layer protocols, MP-BGP extends BGP-4. MP-BGP uses address families to distinguish different network layer protocols. Which of the following address families are currently supported?

BGP-MPexampleIPv6address family

BGP-IPV4broadcast address family

BGP-MPexampleIPv6address family

A company consists of a head office and two branch offices, and uses MPLS VPN technology to transmit private network routes. In the networking mode of HuB&Spoke. Branches can only send and receive routes to and from the head office, and branches cannot directly send and receive routes to each other. In order to achieve the above requirements, which of the following schemes can the setting of RT be?

A campus has deployed IPv6 for service testing. There are 4 routers (R1, 22, R3 and R4) in this network, running 0SPFV3 to realize the interconnection of IPv6 network. A new router R5 needs to be connected to the network for testing. An engineer introduces a direct route in the OSPFVV3 process of R4 so that devices in the campus network can access the GE0/0/1 port address of R5.

Regarding BGP/MPLS IPVPN data forwarding, which of the following descriptions is wrong?

data inB, CP/MPLS IP VPNWhen the backbone network is transmitted, it always carries two layers of labels

The inner label when data is forwarded is defined byMP-BGPdistribute

The outer layer label when data is forwarded can beLDPdistribute

PEsend toCEThe data isIPv4Genuine

From this picture, we can judge

R1Zone authentication is configured

R1Routing domain authentication is set

During the test phase of the cutover, the criteria to indicate that the test has been completed are:

The upper-layer application service test carried by the network is normal as the standard

IPThe configuration view result of the device is normal as the standard

Test that the network service is normal as the standard

The upper-layer application service test carried by the network is normal as the standard
