Configuring RSVP hello extension
When RSVP hello extension is enabled on an interface, the device receives and sends hello
messages through the interface to detect the neighbor's status.
If the device receives a hello request from the neighbor, the device replies with a hello ACK
message. If the device receives no hello request from the neighbor within the interval specified by
the hello interval command, the device sends hello requests to the neighbor.
When the number of consecutive lost hellos or erroneous hellos from the neighbor reaches the
maximum (specified by the hello lost command), the device determines the neighbor is in fault. If
GR is configured, the device serves as a GR helper to help the neighbor to restart. If FRR is
configured, the device performs an FRR. For more information about FRR, see "Configuring MPLS
TE."
