the compatibility of admin-groups received in PATH message against configured admin-groups on
the egress interface of LSP.
To support admin-group for inter-area LSP, the ingress node must configure propagating admin-
groups within the session attribute object. If a PATH message is received by an LSR node that has the
cspf-on-loose option enabled and the message includes admin-groups, then the ERO expansion by
CSPF to calculate the path to the next loose hop will include the admin-group constraints received
from ingress node.
If this option is disabled, then the session attribute object without resource affinity (C-Type 7) is
propagated in PATH message and CSPF at the LSR node will not include admin-group constraints.
This admin group propagation is supported with a P2P LSP, a P2MP LSP instance, and an LSP
template.
The user can change the value of the propagate-admin-group option on the fly. A RSVP P2P LSP
will perform a Make-Before-Break (MBB) on changing the configuration. A S2L path of an RSVP
P2MP LSP will perform a Break-Before-Make on changing the configuration.
Default no propagate-admin-group
vprn-auto-bind
Syntax vprn-auto-bind [include | exclude]
Context config>router>mpls>lsp
Description This command determines whether the associated names LSP can be used or no as part of the auto-
bind feature for VPRN services. By default a names LSP is available for inclusion to used for the
auto-bind feature.
By configuring the command vprn-auto-bind exclude, the associated LSP will not be used by the
auto-bind feature within VPRN services.
The no form of the command resets the flag backto the default value.
Default include
Parameters include — Allows an associated LSPto be used by auto-bin for vprn services
exclude — Disables the use of the associated LSP to be used with the auto-bind feature for VPRN
services.
retry-limit
Syntax retry-limit number
no retry-limit
Context config>router>mpls>lsp
Description This optional command specifies the number of attempts software should make to re-establish the
LSP after it has failed LSP. After each successful attempt, the counter is reset to zero.
