Configuring Load Balancing for Layer 3 VPNs

To configure protocol-independent load balancing for Layer 3 VPNs, include the multipath statement:




multipath {

vpn-unequal-cost equal-external-internal;
}

If you include the multipath statement at the following hierarchy levels, protocol-independent load balancing is applied to the default routing table for that routing instance (routing-instance-name.inet.0):

[edit routing-instances routing-instance-name routing-options]
[edit logical-systems logical-system-name routing-instances routing-instance-name routing-options]

If you include the multipath statement at the following hierarchy levels, protocol-independent load balancing is applied to the specified routing table:

[edit routing-instances routing-instance-name routing-options rib routing-table-name]
[edit logical-systems logical-system-name routing-instances routing-instance-name routing-options rib routing-table-name]

The vpn-unequal-cost statement is optional:

If you do not configure the vpn-unequal-cost statement, protocol-independent load balancing is applied to VPN routes that are equal until the router identifier with regard to route selection.
If you configure the vpn-unequal-cost statement, protocol-independent load balancing is applied to VPN routes that are equal until the IGP metric with regard to route selection.

The equal-external-internal statement is also optional. If you configure the equal-external-internal statement, protocol-independent load balancing is applied to both internal and external BGP paths.
