node-disjoint
Enables node-disjoint on a PLR.
Syntax: node-disjoint {enabled | disabled}
no node-disjoint
Description: Enabling the node-disjoint command on a PLR assures that the immediate downstream primary LSP node will not be considered when signaling the backup path, unless the immediate downstream node is the egress. If node disjoint is disabled, the immediate downstream node from a PLR may be considered when creating a backup path if it is the least biased path available.
Node disjoint is treated as though it were an SRLG with a bias of 1 for all links to primary LSP downstream node.
Node disjoint may be enabled, disabled, or non-specified. If node disjoint is non-specified, command mode precedence determines the node disjoint setting for this PLR.
Factory Default: Enabled
Command Mode: If the PLR is the primary tunnel ingress: Traffic engineering tunnel, Traffic engineering parameter-set, traffic engineering tunnel default, and traffic engineering midpoint default.
If the PLR is a primary tunnel midpoint: Traffic engineering midpoint default and traffic engineering tunnel default.Example 1: In the following example the node-disjoint enable command assures that the immediate downstream primary LSP node from this PLR will not be considered when signaling the backup path for midpoint default command mode:
router(config)#mpls te ospf
router(config-te)midpoint default
router(config-te-midpoint-default)#node-disjoint enabled
router(config-te-midpoint-default)end
router#show mpls te midpoint default
.
. node-disjoint enabled
.
.
Example 2: In the following example the no node-disjoint command set node disjoint to non-specified for the tunnel default command mode for this PLR:
router(config)#mpls te ospf
router(config-te)tunnel default
router(config-te-tunnel-default)#no node-disjoint
router(config-te-tunnel-default)end
router#show mpls te tunnel default
.
. node-disjoint disabled
.
