[3Com-tunnel1] mpls te record-label
mpls te resv-style Syntax
mpls te resv-style [ ff | se ]
undo mpls te resv-style
View
Tunnel view
Parameter
ff: Selects FF (fixed filter) for resource reservation
se: Selects FF (shared explicit) for resource reservation
Description
Using the mpls te resv-style command, you can define resource reservation style in
creating tunnels. Using the undo mpls te resv-style command, you can restore the
default style.
By default, se is selected.
Only RSVP-TE protocol supports both FF and SE modes, so you must first indicate
to run RSVP-TE protocol in creating tunnels before defining resource reservation
style. Each LSP must be configured with a definite reservation style.
The FE type defines a distinct sender list (with IP address and LSP ID defined) and
particular reservation style which is not shared with other senders for each sender.
The FE type is applicable to concurrent but independent services which are from
different senders.
In the SE type, only a single reservation style is defined for an explicit path, which
can be shared by those definitely-listed senders Since the senders are contained in
RESV messages and different labels are allocated with different receiver-sender
pairs, so in this mode separate LSP can be established.
