Context <GLOBAL>

Description
Removes an OAM-type MAC entry from the FIB and optionally floods the OAM MAC removal
throughout the service.
A mac-purge can be sent via the forwarding path or via the control plane. When sending the MAC
purge using the data plane, the TTL in the VC label is set to 1. When sending the MAC purge using
the control plane, the packet is sent directly to the system IP address of the next hop.
A MAC address is purged only if it is marked as OAM.
A mac-purge request is an HVPLS OAM packet, with the following fields. The Reply Flags is set to 0
(since no reply is expected), the Reply Mode and Reserved fields are set to 0. The Ethernet header has
source set to the (system) MAC address, the destination set to the broadcast MAC address. There is a
VPN TLV in the FEC Stack TLV to identify the service domain.
If the register option is provided, the R bit in the Address Delete flags is turned on.
The flood option causes each upstream node to be sent the OAM MAC delete request and to flood the
request along the data plane using the flooding domain. The flooded mac-purge request can be sent
via the data plane or the control plane. The send-control option specifies the request be sent using the
control plane. If send-control is not specified, the request is sent using the data plane.
The register option reserves the MAC for OAM testing where it is no longer an active MAC in the
FIB for forwarding, but it is retained in the FIB as a registered OAM MAC. Registering an OAM
MAC prevents relearns for the MAC based on customer packets. Relearning a registered MAC can
only be done through a mac-populate request. The originating SHG is always 0 (zero).
Parameters

target ieee-address — The MAC address to be purged.
flood — Sends the OAM MAC purge to all upstream nodes.
