This command does not require send-flush-on-failure in B-VPLS to be enabled on an IVPLS trigger
to send an MAC flush into the BVPLS.
Default
no send-bvpls-flush
Parameters
all-but-mine — Specifies to send an LDP flush all-but-mine and also sent into the B-VPLS. Note
all-from-me — Specifies to send an LDP flush-all-from and when STP initiates a flush, it is sent into
send-flush-on-bvpls-failure
Syntax [no] send-flush-on-bvpls-failure
Context config>service>vpls ivpls
Description
This command enables the generation in the local I-VPLS of a LDP MAC flush-all-from-me
following a failure of SAP/the whole endpoint/spoke-SDP in the related B-VPLS. Note that the
failure of mesh-SDP in B-VPLS does not generate the I-VPLS MAC flush.
The no form of this command disables the generation of LDP MAC flush in I-VPLS on failure of
SAP/endpoint/spoke-SDP in the related B-VPLS.
Default no send-flush-on-bvpls-failure
propagate-mac-flush-from-bvpls
Syntax [no] propagate-mac-flush-from-bvpls
Context config>service>vpls ivpls
Description
This command enables the propagation in the local I-VPLS of any regular LDP MAC Flush received
in the related B-VPLS. If an LDP MAC flush-all-but-mine is received in the B-VPLS context, the
command controls also whether a flush is performed for all the customer MACs in the associated I-
VPLS FIB. The command does not have any effect on a PBB MAC Flush (LDP MAC flush with PBB
TLV) received in the related B-VPLS context.
The no form of this command disables the propagation of LDP MAC Flush in I-VPLS from the
related B-VPLS.
Default
no propagate-mac-flush-from-bvpls
send-flush-on-failure
Syntax [no] send-flush-on-failure
Context config>service>vpls
Description
This command enables sending out "flush-all-from-ME" messages to all LDP peers included in
affected VPLS, in the event of physical port failures or "oper-down" events of individual SAPs. This
