disable-learning
Syntax [no] disable-learning
Context config>service>vpls
config>service>vpls>sap
config>service>vpls>spoke-sdp
Description This command disables learning of new MAC addresses in the VPLS forwarding database (FDB) for
the service instance, SAP instance or spoke SDP instance.
When disable-learning is enabled, new source MAC addresses will not be entered in the VPLS
service forwarding database. This is true for both local and remote MAC addresses.
When disable-learning is disabled, new source MAC addresses will be learned and entered into the
VPLS forwarding database.
This parameter is mainly used in conjunction with the discard-unknown command.
The no form of this command enables learning of MAC addresses.
Default no disable-learning (Normal MAC learning is enabled)
discard-unknown
Syntax [no] discard-unknown
Context config>service>vpls
Description By default, packets with unknown destination MAC addresses are flooded. If discard-unknown is
enabled at the VPLS level, packets with unknown destination MAC address will be dropped instead
(even when configured FIB size limits for VPLS or SAP are not yet reached).
The no form of this command allows flooding of packets with unknown destination MAC addresses
in the VPLS.
Default no discard-unknown — Packets with unknown destination MAC addresses are flooded.
