What is wrong with the statement that PTN LTE carries static L3VPN?

In state L3VPW, no signaling is required between PEs

To manually establish a VPN peer (PTN LTE bearer solution adopts fullmesh structure)

Match the routing table to the EPC

The L3VPN routing of the PTN LTE network includes user-side routing and network-side routing.What are the items based on which VPN routing forwarding table is finally generated?

User-side routing needs to be manually configured by the administrator

The PTN6900 at the core layer needs to be configured as a VPN peer relationship

Use the U2000 and the configured user-side routes to automatically calculate and generate network-side routes

User-side routing needs to be manually configured by the administrator

The PTN6900 at the core layer needs to be configured as a VPN peer relationship

Use the U2000 and the configured user-side routes to automatically calculate and generate network-side routes

Use MP-BGP to propagate user-side routes

When the PTN equipment configures the CBS parameters of QoS, the value affects which items are described correctly

The smaller the CBS, the less data is allowed to burst

The larger the CBS, the more packets are allowed to burst

CBS used to describe the capacity of the token bucket C bucket

The smaller the CBS, the less data is allowed to burst

The larger the CBS, the more packets are allowed to burst

The smaller the CBS, the greater the delay in forwarding the packet.

CBS used to describe the capacity of the token bucket C bucket

On the PTN equipment, when the tunnel bears data and forwards, which one is wrong in the description of the actions of each node on the LSP?

lngress encapsulates the data entering the MPLS domain

The Transit node searches the label forwarding information table and performs label switching

In Layer 3 forwarding, the Egress node needs to look up the routing table

CAR is deployed on PTN equipment. Which of the following descriptions is wrong?

CBS bursts are marked in yellow

The value of PIR is required to be greater than or equal to CIR

CBS bursts are marked in yellow

Supports setting the processing mode for CAR-processed packets

The PWE3 technology in the PTN network often uses VLAN. Where is the VLAN in the Ethernet packet?

In PTN, LSP is created statically. Which items are correct in the following description about LSP creation?

The value of the outgoing label of the previous node and the incoming label of the next node are equal

Multiple labels can be assigned to the same A FEC

Tunnel is being created, PHP is not enabled

The value of the outgoing label of the previous node and the incoming label of the next node are equal

Multiple labels can be assigned to the same A FEC

Tunnel is being created, PHP is not enabled

The label values on different nodes of the LSP cannot be the same

What options are included in the role of the control word in PWE3?

Carry the sequence number forwarded by the packet

Fill the message to prevent the message from being too short

Carrying Layer 2 frame header control information

Carry the sequence number forwarded by the packet

Fill the message to prevent the message from being too short

Carrying Layer 2 frame header control information

Which technology can provide synchronization support in TD-SCDMA network?

NE Manager>Board>Optical Power Management

Click on the fiber and cable, right-click and select "Query related optical power"

Configuration > Optical Power Management

NE Manager>Board>Optical Power Management

Click on the fiber and cable, right-click and select "Query related optical power"

Configuration > Optical Power Management

NE Manager > Interface Configuration > Query Optical Power

VLANs are used to isolate Layer 2 broadcast domains. Which of the descriptions of VLANs are correct?

VLAN technology follows IEEE802.1Q standard

The priority field in vlan has a total of 3 bits. The priority value is 0-7. The higher the value, the higher the priority.

VLAN technology follows IEEE802.1Q standard

The VLANID of the school uniform is 12 bits in total, and the value range of the configurable VLAN ID is 0-4095

The value of TPID is 0x8100, which can be changed and can be set arbitrarily without affecting the business

The priority field in vlan has a total of 3 bits. The priority value is 0-7. The higher the value, the higher the priority.
