Configuring Rsvp-Te Advanced Features; Configuring Rsvp Reservation Style - HP HSR6800 Configuration Manual

Establishing an MPLS TE tunnel with RSVP-TE
To use RSVP-TE as the signaling protocol for setting up the MPLS TE tunnel, you must enable both
MPLS TE and RSVP-TE on the interfaces for the tunnel to use on each node along the tunnel.
To establish an MPLS TE tunnel with RSVP-TE:
Step
1. Enter system view.
2. Enter MPLS view.
3. Enable RSVP-TE on your
device.
4. Exit to system view.
5. Enter interface view of MPLS
TE link.
6. Enable RSVP-TE on the
interface.
7. Enter MPLS TE tunnel
interface view.
8. Set the signaling protocol for
setting up the MPLS TE
tunnel to RSVP-TE.
9. Submit current tunnel
configuration.

Configuring RSVP-TE advanced features

RSVP-TE adds new objects in Path and Resv messages to support CR-LSP setup. RSVP-TE
provides many configurable options with respect to reliability, network resources, and other
advanced features of MPLS TE.
Before performing the configuration tasks in this section, be aware of each configuration objective
and its impact on your network.
Before you configure RSVP-TE advanced features, complete the following tasks:
•
Configure basic MPLS.
•
Configure basic MPLS TE.
•
Establish an MPLS TE tunnel with RSVP-TE.

Configuring RSVP reservation style

Each LSP set up using RSVP-TE is assigned a resource reservation style. During an RSVP session,
the receiver decides which reservation style can be used for this session and thus which LSPs can
be used.
The following reservation styles are available:
•
FF—Resources are reserved for individual senders and cannot be shared among senders on
the same session.
•
SE—Resources are reserved for senders on the same session and shared among them.
In current MPLS TE applications, the SE style is mainly used for make-before-break. The FF style is
rarely used.
