A.TRUE

B.FALSE

A.Router-LSA Network-LsA and does not contain routing information

B.Inter-Area Prefix-LSA Link State id, contains the preceding information

C.Inter-Area-Prefix LSA Link-Local also contains information

D.When the Intra-Area Prefix LSA Referenced Link State Type-2, Referenced, the Link State id DR id
contains the interface

A.The host unicasts an IGMPv2 Membership Report message to the default router on the local network.

B.The host multicasts an 1GMPv2 Membership Report message that carries the expected multicast address to the local network.

C.The host multicasts an IGMPv2 Membership Report message with the multicast address for all PIM routers (224.0.0.2) to the local network.

D.The host unicasts an IGMPv2 Membership Report message to the RP.

A.In Uniform mode, when IP packets enter an MPLS network, the ingress node decrements the IP TTL by one and the MPLS TTL field has a fixed value.

B.In Pipe mode, when IP packets enter an MPLS network, the ingress node decrements the IP TTL by one and copies this new value to the MPLS TTL field.

C.On an MPLS VPN, if the structure of the MPLS backbone network needs to be shielded, the Uniform mode is recommended for VPN packets,

D.The TTL field in an MPLS label serves the same function as that in an IP packet header. That is, the TTL is used to prevent loops on an MPLS network.

A.R2 10.1.1.0/24 can learn this route.

B.R2 10.1.2.0/24 10.1.3.0/24 can learn and two routes.

C.R2 R1 LSP can be received but cannot be added to the routing table.

D.R2 R1 can learn all the routes of the study
