Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MPLS TE tunnel interface
view.
interface tunnel tunnel-number N/A
3. Configure the resources
reservation style for the tunnel. mpls te resv-style { ff | se }
Optional.
The default resource reservation
style is SE.
4. Submit current tunnel
configuration.

In current MPLS TE applications, the SE style is mainly used for make-before-break, while the FF style is
rarely used.
Configuring RSVP state timers
To configure RSVP state timers:
Step Command Remarks

3. Configure the
path/reservation state refresh
interval of the node.
mpls rsvp-te timer refresh
timevalue
Optional.
The default path/reservation state
refresh interval is 30 seconds.
4. Configure the keep multiplier
for PSB and RSB. mpls rsvp-te keep-multiplier
number Optional.
The default is 3.
5. Configure the blockade
timeout multiplier.
mpls rsvp-te blockade-multiplier
number
Optional.
The default blockade timeout
multiplier is 4.
Configuring the RSVP refreshing mechanism
To enhance reliability of RSVP message transmission, the Message_ID extension mechanism is used to
acknowledge RSVP messages. The Message_ID extension mechanism is also referred to as the reliability
mechanism throughout this document.
After you enable RSVP message acknowledgement on an interface, you may enable retransmission.
To use summary refresh (Srefresh), you must use the Message_ID extension. Only states advertised using
MESSAGE_ID included Path and Resv messages can be refreshed using summary refreshes.
To configure RSVP refreshing mechanism:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view of MPLS
TE link.
interface interface-type interface-number N/A
