Question 175

Regarding the MPLS forwarding process, the description of Ingress node forwarding is correct:

IngressAfter the node receives the data packet, it will first checkILMlooking forTunnel ID

existIPThe obtained label is pressed into the packet, and according to theQoSPolicy processingEXRSimultaneous processingL,,Then the packagedMPLSThe packet is sent to the next hop

according toILMtableTunnel IDfind the correspondingNHLFEentry, willLFIBentry andNHLFEtable entry

CheckNHLFETable entry, you can get outbound interface, next hop, outbound label and label operation type The label operation type isPush

Question 178

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, a description of the two-layer label in the following options. What is wrong is:

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

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

M PLS VPNThe outer layer is labeled as a private network label, and the inner layer label is called a public network label.

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