Context config>router>rsvp>diffserv-te
config>router>rsvp>interface
Description This command configures the percentage of RSVP interface bandwidth each CT shares, for example,
the Bandwidth Constraint (BC).
The absolute value of the CT share of the interface bandwidth is derived as the percentage of the
bandwidth advertised by IGP in the Maximum Reservable Link Bandwidth TE parameter, for
example, the link bandwidth multiplied by the RSVP interface subscription percentage parameter.
Note this configuration also exists at RSVP interface level and the interface specific configured value
overrides the global configured value. The BC value can be changed at any time.
The RSVP interface subscription percentage parameter is configured in the
config>router>rsvp>interface context.
The operator can specify the Bandwidth Constraint (BC) for a CT which is not used in any of the TE
class definition but that does not get used by any LSP originating or transiting this node.
When Diff-Serv is disabled on the node, this model degenerates into a single default CT internally
with eight pre-emption priorities and a non configurable BC equal to the Maximum Reservable Link
Bandwidth. This would behave exactly like CT0 with eight pre-emption priorities and BC=
Maximum Reservable Link Bandwidth if Diff-Serv was enabled.
The no form of this command reverts to the default value.
Parameters
ct0 (ct1/ct2/ — ct7) % link-bandwidth — The Diff-Serv Class Type number. One or more system
