DETAILED STEPS
Step 1 configure
Example:
RP/0/RSP0/CPU0:router# configure
Enters the Global Configuration mode.
Step 2 l2vpn
Example:
RP/0/RSP0/CPU0:router(config)# l2vpn
Enters L2VPN configuration mode.
Step 3 load-balancing flow {src-dst-mac | src-dst-ip}
Example:
RP/0/RSP0/CPU0:router(config-l2vpn)# load-balancing flow src-dst-ip
Enables flow based load balancing.
• src-dst-mac—Uses source and destination MAC addresses for hashing.
• src-dst-ip—Uses source and destination IP addresses for hashing.
It is recommended to use the load-balancing flow command with the src-dst-ip keyword.
Note
Step 4 pw-class { class - name }
Example:
RP/0/RSP0/CPU0:router(config-l2vpn)# pw-class class1
Associates the pseudowire class with this pseudowire.
Step 5 encapsulation mpls
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-pwc)# encapsulation mpls
Configures the pseudowire encapsulation to MPLS.
Step 6 load-balancing flow-label { both | code | receive | transmit } [ static ]
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-pwc-mpls)# load-balancing flow-label both
Enables load-balancing on ECMPs. Also, enables the imposition and disposition of flow labels for the pseudowire.
