This section shows a configuration example for three 7750 SR, 7450 ESS, or 7950 XRS PEs, all the following assumptions are considered:
PE-1 and PE-2 are multihomed to CE-12 that uses a LAG to get connected to the network. CE-12 is connected to LAG SAPs configured in an all-active multihoming Ethernet segment.
PE-3 is a remote PE that performs aliasing for traffic destined for the CE-12
The following configuration excerpt applies to a VPLS-1 on PE-1 and PE-2, as well as the corresponding Ethernet-segment and LAG commands.

The configuration on the remote PE (PE-3), which supports aliasing to PE-1 and PE-2 is shown below. PE-3 does not have any Ethernet-segment configured. It only requires the VPLS-1 configuration and ecmp>1 to perform aliasing.
