Command or Action
path-option 1 explicit identifier 10
Step 5 path-option preference-priority dynamic
Example:
RP/0/RP0/CPU0:router(config-if-p2mp-dest)#
path-option 2 dynamic
Step 6
exit
Example:
RP/0/RP0/CPU0:router(config-if-p2mp-dest)# exit
RP/0/RP0/CPU0:router(config-if)#
Step 7 destination ip-address
Example:
RP/0/RP0/CPU0:router(config-if)# destination
172.16.255.2
RP/0/RP0/CPU0:router(config-if-p2mp-dest)#
Step 8
path-option preference-priority explicit name pathname
Example:
RP/0/RP0/CPU0:router(config-if-p2mp-dest)#
path-option 1 explicit name
how-to-get-to-172.16.255.2
Step 9 path-option preference-priority dynamic
Example:
RP/0/RP0/CPU0:router(config-if-p2mp-dest)#
path-option 2 dynamic
Step 10
exit
Example:
RP/0/RP0/CPU0:router(config-if-p2mp-dest)# exit
RP/0/RP0/CPU0:router(config-if)#
Step 11 destination ip-address
Example:
RP/0/RP0/CPU0:router(config-if)# destination
172.16.255.3
Purpose
Specifies that label switched paths (LSP) are dynamically
calculated.
Exits the current configuration mode.
Sets the destination address for tunnel-mte 10 to
172.16.255.2.
Specifies the path name of the IP explicit path. Destination
172.16.255.2 uses the explicit path that is identified by the
explicit path name "how-to-get-to-172.16.255.2."
Sets the fall back path option as dynamic when the
destination cannot come to the explicit path.
Exits the current configuration mode.
Specifies that destination 172.16.255.3 uses only the
dynamically computed path.
