8.17.3 Neighbors
The Hello Protocol is responsible for neighbor acquisition, maintenance, and
for 2-way communication between neighbors.
During acquisitioning, the routers on a segment compare their configurations
for compatibility. When the routers are compatible, then the routers form
adjacencies. The routers discover their master or slave status using
information provided in the hello packets.
After the routers discover their roles they exchange routing information to
synchronize their routing databases. When the routers finish updating their
databases, the neighbors are fully adjacent and the LSA lists the adjacency.
Table
Parameters Meaning
Neighbor ID Displays the router ID of the neighboring router.
The router learns this value from hello packets received from the neighbor.
The value is a static value for virtual adjacencies.
IP Address Displays the IP address of the neighboring router interface attached to the
port.
The router uses the value as the destination IP address when sending
unicast protocol packets on this adjacency. If the neighboring router is the
DR, the router also used in router LSAs as the link ID for the attached
network. The router learns the neighbor IP address when it receives hello
packets from the neighbor. For virtual links, the router learns the neighbor
IP address while building the routing table.
Possible values:
Valid IPv4 address
Interface Displays the interface to which the entries in this row refer.
