To constrain the bandwidth adjustment that can be made to an LSP in an LSP attribute list, use the
max-bw or min-bw keyword and specify the permitted maximum allowable bandwidth or minimum
allowable bandwidth, respectively.
The no form of the auto-bw command disables bandwidth adjustment for the tunnel and restores the
configured bandwidth for the LSP where configured bandwidth is determined as follows:
• If the LSP bandwidth was explicitly configured with the mpls traffic-eng lsp attributes lsp-id
bandwidth command after the running configuration was written (if at all) to the startup
configuration, the configured bandwidth is the bandwidth specified by that command.
• Otherwise, the configured bandwidth is the bandwidth specified for the tunnel in the startup
configuration.
To associate the LSP automatic bandwidth adjustment attribute and the LSP attribute list with a path
opt
ion for an LSP, you must configure the tunnel mpls traffic-eng path option command with the
attributes string keyword and argument, where string is the identifier for the specific LSP attribute list.
Examples The following example sets automatic bandwidth configuration for an LSP in an LSP attribute list:
configure terminal
!
mpls traffic-eng lsp attributes 1
auto-bw
exit
end
