MPLS Commands
adaptive
Syntax [no] adaptive
Context config>router>mpls>lsp
Description
This command enables the make-before-break functionality for an LSP or LSP path. When enabled
for the LSP, make-before-break will be performed for primary path and all the secondary paths of the
LSP.
Default adaptive
adspec
Syntax [no] adspec
Context config>router>mpls>lsp
config>router>mpls>lsp-template
Description When enabled, the ADSPEC object will be included in RSVP messages for this LSP. The ADSPEC
object is used by the ingress LER to discover the minimum value of the MTU for links in the path of
the LSP. By default, the ingress LER derives the LSP MTU from that of the outgoing interface of the
LSP path.
Note that a bypass LSP always signals the ADSPEC object since it protects both primary paths which
signal the ADSPEC object and primary paths which do not. This means that MTU of LSP at ingress
LER may change to a different value from that derived from the outgoing interface even if the
primary path has ADSPEC disabled.
Default no adspec — No ADSPEC objects are included in RSVP messages.
auto-bandwidth
Syntax [no] auto-bandwidth
Context config>router>mpls>lsp
config>router>mpls>lsp-template
Description This command enables (and the no form disables) automatic adjustments of LSP bandwidth.
Auto-bandwidth at the LSP level cannot be executed unless adaptive is configured in the
config>router>mpls>lsp context.
Default no auto-bandwidth
