Hi,

The Hello packet contains the transport address field. The router uses this field to set up a TCP connection with the peer. By default, the value of the transport address is the same as that of LSR ID. Therefore, only one neighbor relationship is established between R1 and R2.

What if the transport address is changed to a physical interface address?

If the transport address is changed to a physical interface address, two TCP connections will be established between R1 and R2. The initialization message sent afterward also carries the LSR-ID. At this time, a TCP connection will be closed.

We have only one relationship between AR1 and AR2.
But under relationship, we have two paths to another peer.
