This feature is supported with the following LSP types and in both intra-area and inter-area TE where
applicable:
The no form of this command disables the signaling of administrative group constraints in the FRR
object.
Default no propagate-admin-group
max-bypass-associations
Syntax max-bypass-associations integer
no max-bypass-associations
Context config>router>mpls
Description This command allows the user to set a maximum number of LSP primary path associations with each
manual or dynamic bypass LSP that is created in the system.
By default, a Point of Local Repair (PLR) node will associate a maximum of 1000 primary LSP paths
with a given bypass before using the next available manual bypass or signaling a new dynamic
bypass.
Note that a new bypass LSP may need to be signaled if the constraint of a given primary LSP path is
not met by an existing bypass LSP even if the max-bypass-associations for this bypass LSP has not
been reached.
The no form of the command re-instates the default value of this parameter.
Default no max-bypass-associations
mbb-prefer-current-hops
Syntax [no] mbb-prefer-current-hops
Context config>router>mpls
Description This command implements a new option in the CSPF path computation during a Make-Before-Break
(MBB) procedure of an RSVP LSP.
When MPLS performs an MBB for the primary or secondary path of a P2P LSP, or the S2L path of a
P2MP LSP, and the new mbb-prefer-current-hops option is enabled in MPLS context, CSPF will
select a path, among equal-cost candidate paths, with the most overlapping links with the current
path. Normally, CSPF selects the path randomly.
The procedures of the new MBB CSPF path selection apply to LSP without the least-fill option
enabled. If the least-fill rule results in a different path, the LSP path will be moved though. Users can
still favor stability over least-fill condition by applying a larger value to the parameter least-fill-min-
