If it does not exist, the receiving router creates a new adjacency relationship, which is set to "initialization" state, and the system type is "unknown". The IIH response is then sent . If the router receives an IIH packet from the new neighbor , the router sets the adjacency to UP and the system type is IS . However, there is a problem here. After the local IIH is sent, I don’t know if the other party is If it is received, then there is a possibility that the message will be lost in the middle and the UP side will be DOWN . So we introduced a three-way handshake mechanism, see below.
