Configuring RSVP Srefresh and reliable RSVP
message delivery
After Srefresh is enabled, RSVP maintains the path and reservation states by sending Srefresh
messages rather than standard refresh messages.
To configure Srefresh and reliable RSVP message delivery:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Enable Srefresh and reliable
RSVP message delivery.
4.
Set the retransmission
increment value for reliable
RSVP message delivery.
5.
Set the retransmission
interval for reliable RSVP
message delivery.
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
TE."
