Dynamic Bypass LSPs

Use the [no] form of the command inside global dynamic-bypass configuration mode to disable
dynamic bypass on all existing MPLS interfaces.
Setting the maximum number of dynamic bypass LSPs
The maximum number of dynamic bypass LSP is configurable in global mode. This is the limit for
the total number of dynamic bypass LSPs that can be created on a router. This number must be
less than, or equal to, the global maximum number of bypass LSPs that can be configured on a
router. The maximum number of bypass LSPs supported on a device is currently limited to 1000.
The means that the maximum number of dynamic bypass LSP that can be configured on a system
is always (1000 – (current number of configured Bypass LSPs)). When the max-bypasses limit is
changed to a value which is less than current active number of dynamic bypasses, the limit is
changed to the new value and this limit is considered for next new creations. Existing exceeding
number dynamic bypasses are not deleted. To enable dynamic bypass on one or more MPLS
interfaces, enter a command such as the following.
Brocade(config-mpls-dynamic-bypass)# max-bypasses 150
Brocade(config-mpls-dynamic-bypass)#
Syntax: [no] max-bypasses number
The number parameter is the maximum number of dynamic bypasses that can be created on the
system.
Use the [no] form of the command to returns the settings to the default value.
Setting the maximum number of dynamic bypass LSPs per MP
Use the max-bypasses-per-mp command to set the maximum number of dynamic bypass LSP
configurable on a MPLS interface mode. This global value is taken as the interface mode maximum
bypasses per MP default value. This is the limit for the total number of dynamic bypass LSPs
created to a merge point corresponding to a protected interface. A PLR may have ‘M’ number of
merge points with respect to a protected LSPs. There may be ‘N’ number of protected LSPs riding
on an interface with dynamic bypass enabled. Max-bypasses configurations limits the maximum
number of dynamic bypass LSPs to each merge point. When the max-bypasses-per-mp limit
changes to a value which is less than the current active number of dynamic bypasses, the limit
changes to the new value and this limit is considered for the next creations. Existing dynamic
bypasses exceeding the new limit do not delete. When the max-bypasses-per-mp limit changes to a
value which is more than the system max-bypasses limit, this creates a warning message.
Use the max-bypasses-per-mp command to change the maximum number of dynamic bypass LSP
on a a MPLS interface mode.
Brocade(config-mpls-dynamic-bypass)# max-bypasses-per-mp 8
Brocade(config-mpls-dynamic-bypass)#
Syntax: [no] max-bypasses-per-mp number
Use the number parameter to set the maximum number of dynamic bypass that may be created to
a merge point from a PLR. The range of valid values is from 1 to 1000. The default value is the
same as the max-bypasses parameter value.
Use the [no] form of the command to return the settings to the default values.
