node-protect
Syntax [no] node-protect
Context config>router>mpls>lsp>fast-reroute
Description This command enables or disables node and link protection on the specified LSP. Node protection
ensures that traffic from an LSP traversing a neighboring router will reach its destination even if the
neighboring router fails.
Default
node-protect
from
Syntax from ip-address
Context config>router>mpls>lsp
Description This optional command specifies the IP address of the ingress router for the LSP. When this
command is not specified, the system IP address is used. IP addresses that are not defined in the
system are allowed. If an invalid IP address is entered, LSP bring-up fails and an error is logged.
If an interface IP address is specified as the from address, and the egress interface of the nexthop IP
address is a different interface, the LSP is not signaled. As the egress interface changes due to
changes in the routing topology, an LSP recovers if the from IP address is the system IP address and
not a specific interface IP address.
Only one from address can be configured.
Default The system IP address
Parameters
ip-address — This is the IP address of the ingress router. This can be either the interface or the system
hop-limit
Syntax hop-limit number
no hop-limit
Context config>router>mpls>lsp
config>router>mpls>lsp>fast-reroute
Description This command specifies the maximum number of hops that an LSP can traverse, including the ingress
and egress routers. An LSP is not set up if the hop limit is exceeded. This value can be changed
dynamically for an LSP that is already set up with the following implications:

IP address. If the IP address is local, the LSP must egress through that local interface which
ensures local strictness.
Default
System IP address
Values
System IP or network interface IP addresses
If the new value is less than the current number of hops of the established LSP, the LSP is
brought down. Software then tries to re-establish the LSP within the new hop-limit number. If
