mpls field

Function

The mpls field command configures a load balancing mode of MPLS packets in a load balancing profile.

The undo mpls field command deletes a specified load balancing mode of MPLS packets or restores the default load balancing modes of MPLS packets.

By default, load balancing of MPLS packets is based on the two outer labels (top-label and 2nd-label) of each packet.

Only the S5720-EI, S5720-HI, S5730-HI, S5730S-EI, S5730-SI, S5731-H, S5731S-H, S5732-H, S6720-EI, S6720-HI, S6720-LI, S6720S-EI, S6720S-LI, S6720S-SI, S6720-SI, S6730S-H, and S6730-H support this command.

Usage Guidelines

Usage Scenario

The undo mpls field command with no parameter specified restores the default load balancing modes of MPLS packets. The undo mpls field command with a parameter specified deletes a specified load balancing mode of MPLS packets.

The mpls field 3rd-label command implements flow label-based load balancing on L2VPN networks.

Precautions

If you run the mpls field command multiple times, only the latest configuration takes effect.
Only the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support the 3rd-label, l4-dport, l4-sport, and protocol load balancing mode.
Only 2nd-label, dmac, smac, sport, and top-label are supported on the S5730-SI, S5730S-EI, S6720-LI, S6720S-LI, S6720-SI, and S6720S-SI.
Load balancing based on MPLS labels takes effect for only labeled packets on the ingress.
For the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S, MPLS packets can be load balanced based on source or destination IP addresses on the P and tunnel egress on an L2VPN network. If original data packets are Layer 2 packets and the sip or dip parameter is specified, MPLS packets are load balanced based on source or destination MAC addresses. For other models, load balancing based on source or destination IP addresses for MPLS packets does not take effect on the P and tunnel egress on an L2VPN network. You are advised to configure the 2nd-label, 3rd-label, or top-label load balancing mode.

Example

# In the load balancing profile a, set the load balancing mode of MPLS packets to 2nd-label, that is, load balancing based on the second label of MPLS packets.
