Pseudowire Redundancy with Uni-directional Active-Active

Pseudowire redundancy with uni-directional active-active feature configuration allows, pseudowires (PW)
on both the working and protect circuits to remain in UP state to allow traffic to flow from the upstream. The
aps l2vpn-state detach command and redundancy all-active replicate command is introduced to configure
uni-directional active-active pseudowire redundancy.
In pseudowire redundancy Active-Standby mode, the designation of the active and standby pseudowires is
decided either by the endpoint PE routers or by the remote PE routers when configured with MR-APS. The
active and standby routers communicate via Protect Group Protocol (PGP) and synchronize their states. The

Pseudowire Redundancy with Uni-directional Active-Active
Purpose
Configures the backup delay parameters.
Where:
• enable-delay—Time before the backup PW takes over
for the primary PW.
• disable-delay—Time before the restored primary PW
takes over for the backup PW.
• never—Disables switching from the backup PW to
the primary PW.
Binds the Ethernet port interface to an attachment circuit to
create a pseudowire.
Defines the address and VC of the backup peer.
Exits configuration mode.
