Subsequent fragmented packets

Non-fragmented packets

Forged ICMP error message

The first fragmented packet

Q112. The LDP session is used to exchange messages such as label mapping and release between LSRs. Regarding the description of the LDP session establishment process, which of the following is correct? (Multiple choice)

Initialization Message is used to negotiate parameters during LDP Session establishment

When the ingress node LSR receives the label mapping message, it completes the establishment of the LDP session

KeepAlive Messagel is used to monitor the integrity of the TCP connection of the LDP Session

Two LSRs exchange Hello messages to trigger the establishment of an LDP session
