On a VPLS network a PE router receive a packet that containers layer 2 user data from a PE .
How does the PE router determine the source VSI of this packet?
- A . Outer label of the packets
- B . Destination MAC address in the L2 PDU encapsulation in the packet
- C . MAC address and VLAN ID in the PDU encapsulated in the packet
- D . Inner label of the packet
When the RSVP LSP FRR protection is enables, which of the following statements about the original RSVP LSP are true?
- A . The point of local repair (PLR) and the merge point (MP) can perceive the application of FRR but other nodes on the original RSVP LSP
- B . The RESV message is sent by the MP to an upstream node through a bypass LSP after modified.
- C . The PATH message is sent by the PLR to the MP through a bypass LSP after modified.
- D . The MP sends the ResvTear message to the upstream node of the original RSVP LSP.
As shown I the figure, the asymmetric VLL FRR networking is used AC interfaces on PE 1, PE 2 and PE 3 are configured as follows:
Which of the following statements are the true on the condition that IGP and MPLS are configured correctly on the public network?
- A . If a forwarding fault is detected on the PW between PE a and PE 2, traffic from CE 1 to CE 2 can be switched to the PW between PE 1 and PE 3.
- B . If a forwarding fault is detected on the PW between PE a and PE 2, traffic can be switched to the backup PW on PE 1.
- C . If a forwarding fault is detected on the public network side of the between PE 1 and PE 2, traffic from CE 2 to CE 1 can be switched to the PW between PE 1 and PE3.
- D . The PW between PE1 and PE 2 is the primary PW.
Which of the following statements about the working principle f LDAP FRR are true?
- A . After LDP FRR is enabled, a backup LSP is generated both the primary and backup LSPs are stored in the forwarding table.
- B . LDP TFRR can be deployed on the ingress node and the intermediate node. The primary and backup LSPas are recorded in the ILM table on the intermediate node and on the FIB table on the ingress node.
- C . After LDP FRR enable, a backup can degenerated for a primary LSP to prevent serious packet loss during fats flapping of the primary LSP.
- D . Multiple LSPs can be up on the ingress node, that is entries about multiple backup LSPs are generated in the forwarding table according to the priority of the FRR, implementing multi-layer protection.
In MPLS QoS , traffic policies are developed on simple traffic classified and complex traffic classification policies based on simple traffic classification the service class color, and drop priority of packet are reset based on the packet in the traffic policies on complex traffic classification measures such as traffic classification is applied on border routers in Different domain, and traffic classification core routers.
QoS policies are configured by performing the following operations:
Defines DiffSer domain and configuring a traffic policy.
Classification traffic
Defines traffic behavior and configures characteristics of behaviors.
Defines a traffic policy and specifies for traffic categories
Applies the traffic policy
Configure L-LSP
Configures reserve address checks
Adds interface to the DiffSer domain
Which of the proceeding operations are required when you configured simple traffic classification?
- A . 1 6 8
- B . 2 3 4 8
- C . 1 5 6
- D . 2 4 5 7
