tunnel mpls traffic-eng path-option protect

Cisco IOS Multiprotocol Label Switching Command Reference

Command History
Usage Guidelines Cisco recommends that the primary path options being protected use explicit paths.
Calculation of a dynamic path for the path protected LSP is not available. When configuring the IP
e
xplicit path for the path protected LSP, choose hops that minimize the number of links and nodes shared
with the primary path option that is being protected.
If the path option being protected uses an attribute list, configure path protection to use the same attribute
li
st.
If the path option being protected uses bandwidth override, configure path protection to use bandwidth
o
verride with the same values.
Examples The following example shows how to configure the tunnel to use a named IP explicit path:
Router(config-if)# tunnel mpls traffic-eng path-option protect 1 explicit name test
The following example shows how to configure path option 1 to use an LSP attribute list identified with
the numeral 1:
Router(config-if)# tunnel mpls traffic-eng path-option protect 1 explicit name test
attributes 1
The following example shows how to configure bandwidth for a path option to override the bandwidth
configured on the tunnel:
Router(config-if)# tunnel mpls traffic-eng path-option protect 3 explicit name test
bandwidth 0
