NEW QUESTION 225
In a certain MPLS network, the LSP information of R1 and R2 is shown in the figure. At this time, the administrator enters the command ping 3.3.3.3 on R1. Which of the following descriptions of this scenario is correct?

The Ping message sent by R1 does not carry any label. After receiving it, R2 will forward it based on IP.

The Ping message sent by R1 will carry label 1025. After receiving it, R2 will remove the label and forward it based on IP.

The Ping message sent by R1 will carry label 1025. After receiving it, R2 will perform label exchange and forward it based on MPLS.

NEW QUESTION 229
On the OSPFv3 network shown in the figure, OSPFv3 is enabled on the interfaces connecting R1, R2, and R3. The router ID of each router is 10.0.X.X, where X is the number of the router. If you check detailed information about an LSA on R3, the command output shows that the LSA is generated by R2 and describes the IPv6 prefix address associated with the Router-LSA.

TRUE

FALSE

NEW QUESTION 230
In the network shown in the figure, ASs use directly connected interfaces to establish EBGP neighbor relationships. OSPF is deployed inside AS 65456 (OSPF is not enabled on the interconnection ports between ASs), and R4 and R5 use the Loopback0 interface to establish an IBGP neighbor relationship with R6. The IP address of the Loopback0 interface of each device is
10.0.X.X/32, and the Router ID is 10.0.X.X, where X is the device number. R1, R2, and R3 introduce the external network 192.168.1.0/24 into BGP through import.

Which of the following descriptions are correct by default? (Multiple choice)

For 192.168.1.0/24, R6 prefers the route received from R4

For 192.168.1.0/24, R4 prefers the route received from R1

For 192.168.1.0/24, if R3 is configured with “default local-preference 150”, R5 will prefer the route received from R3.

For 192.168.1.0/24, R5 prefers the route received from R2

NEW QUESTION 231
In an MPLS network that uses LDP to establish LSP, when the directly connected downstream transit node of the ingress node that sends a label request will distribute labels to the ingress only after receiving the label mapping message from the final downstream egress node, which of the following combinations of label publishing mode and label distribution control mode is used at this time?

DU + Ordered

BGP-VPNv4address family

BGP-IPV6Unicast address family

BGP-IPV4broadcast address family

BGP-MPexampleIPv6address family
