Dynamic Bypass LSPs

Setting the reoptimizer-timer
When the re-optimization value is set to a non-zero value and the timer sets the amount of
seconds, the reoptimizer-timer command enables the dynamic bypass LSP re-optimization. The
re-optimization timer value is configurable on all MPLS interface modes. The global set value is
applicable to all dynamic bypass LSPs for which corresponding interface level re-optimization timer
value is not set.
Brocade(config-mpls-dynamic-bypass)# reoptimize-timer 300
Brocade(config-mpls-dynamic-bypass)#
Syntax: [no] reoptimizer-timer number
Use the number parameter to set the re-optimization timer value in seconds for the dynamic
bypass LSPs. The range of valid values is from 300 to 65535. The default value is zero, which
means re-optimization is disabled.
Use the [no] form of the command to return the settings to the default value.
Enabling dynamic bypass per interface
Use the enable-all-interfaces command to configure a dynamic bypass as enabled on a MPLS
interface. There is no change in the dynamic bypass configured state (enabled or disabled), when
already configured on the interface. When the user configures a dynamic bypass on a MPLS
interface using this command, this is called a user configured interface level dynamic bypass
configuration. Dynamic bypass is disabled, by default, in interface mode unless it is enabled
through global configured enable-all-interfaces command.
When the dynamic bypass is already enabled on the interface through global enable-all-interfaces
command, this command changes the interface status to the user configured interface level
dynamic bypass configuration. When the user configures the interface level dynamic bypass to the
disabled status, this command retains the existing disabled state. When an interface level dynamic
bypass is enabled, a facility protected LSP does not use a dynamic bypass LSP.
Use the dynamic-bypass command to enable the dynamic bypass on a MPLS interface.
Brocade(config-mpls-if-e100-2/3)# dynamic-bypass
Brocade(config-mpls-if-e100-2/3-dynamic-bypass)#enable
Syntax: [no] dynamic-bypass
Syntax: enable
The [no] form of the command disables dynamic bypass on the MPLS interface.
Setting the maximum number of dynamic bypass LSPs per MP
Use the max-bypassesper-mp command to set the maximum number of dynamic bypass LSPs that
are configurable MPLS interface mode. This is the limit for total number of dynamic bypass LSPs
that can be created to a merge point. When this parameter is not configured under interface mode,
the global max-bypasses-per-mp parameter value is considered for this parameter. A PLR can have
‘M’ number of merge points with respect to a Protected LSP. There can be ‘N’ number of protected
LSPs riding on an interface with a dynamic bypass enabled. By default, the maximum number of
