IP As the core protocol of the network layer in the TCP/IP protocol stack, the fixed part of the packet header has 20 bytes and carries a variety of identification fields to define the transmission of the data packet.Which of the following statements about the identification field is incorrect?

Total Length (16bit), indicating the length of the IP header

version (4bit), identifies the IP version, the current iP version is 4, and the next generation version is 6

TLN Time to live, 8bit), when an IP packet is generated, an initial value will be set, and when an old packet is forwarded from one router to another, the TTL value will decrease by 1. When the TTL is 0, the packet will be discarded

Protocol (8bit), indicating the protocol type to which the IP payload belongs, and a value of 6 indicates that the IP encapsulation is a TCP segment

Total Length (16bit), indicating the length of the IP header

Configure the default route on the standby point, and the next hop points to the standby L2/L3 node

The default route is configured on the L2/3 master node, and the next-hop points to the L3 master node

A default route is configured on the L2/L3 standby node, and the next hop points to the L3 master node

On the L3 raw node, configure a default route with the next hop pointing to the main L2/L3 node

Configure the default route on the standby point, and the next hop points to the standby L2/L3 node

In the LTE service, X2 traffic forwarding between base stations needs to be enabled. Which of the following statements about the forwarding path in the x2 traffic flow is correct?

For forwarding in the X2 flow between base stations on different network segments under the same L2L3 node, it is necessary to transfer between L3VE sub-interfaces

X2 traffic forwarding on the same network segment does not require Layer 3 routes or interfaces

For forwarding in the X2 flow between base stations on different network segments under the same L2L3 node, it is necessary to transfer between L3VE sub-interfaces

Different L2L3 nodes must forward the X2 traffic with the base station to the base station, and it must be transited by the L3 node.

X2 traffic forwarding between different cities requires SGW participation
