2.8.3 Example for Connecting an E-Trunk to a VPLS Network

Networking Requirements
If no E-Trunk is configured, a CE can be connected to only one PE using an Eth-Trunk. If the
Eth-Trunk or the PE is fails, the CE cannot communicate with the PE. After an E-Trunk is
configured, the CE can be dual homed to PEs to improve link reliability between devices.
As shown in
using two Eth-Trunks in static LACP mode.
Initially, CE1 communicates with CE2 on the VPLS network through PE1. If PE1 or the Eth-
Trunk between CE1 and PE1 fails, CE1 cannot communicate with CE2. To prevent service
interruption, configure an E-Trunk on PE1 and PE2. When communication between CE1 and
PE1 fails, traffic is switched to PE2 so that CE1 can communicate with CE2 through PE2. When
PE1 or the Eth-Trunk between CE1 and PE1 recovers, traffic is switched back to PE1.
The E-Trunk implements backup of link aggregation groups between PE1 and PE2 and hence
improves network reliability.
