mld-snooping
Syntax mld-snooping
Context config>service>vpls
config>service>vpls>sap
Description This command configures MLD snooping parameters.
remote-age
Syntax remote-age seconds
no remote-age
Context config>service>vpls
Description Specifies the aging time for remotely learned MAC addresses in the forwarding database (FDB) for
the Virtual Private LAN Service (VPLS) instance. In a VPLS service, MAC addresses are associated
with a Service Access Point (SAP) or with a Service Distribution Point (SDP). MACs associated with
a SAP are classified as local MACs, and MACs associated with an SDP are remote MACs.
Like in a layer 2 switch, learned MACs can be aged out if no packets are sourced from the MAC
address for a period of time (the aging time). In each VPLS service instance, there are independent
aging timers for local learned MAC and remote learned MAC entries in the FDB. The remote-age
timer specifies the aging time for remote learned MAC addresses. To reduce the amount of signaling
required between switches configure this timer larger than the local-age timer.
The no form of this command returns the remote aging timer to the default value.
Default remote age 900 — Remote MACs aged after 900 seconds
Parameters seconds — The aging time for remote MACs expressed in seconds.
Values 60 — 86400
send-bvpls-flush
Syntax send-bvpls-flush {[all-but-mine] [all-from-me]}
no send-bvpls-flush
Context config>service>vpls
Description This command enables generation of LDP MAC withdrawl “flush-all-from-me” in the B-VPLS
domain when the following triggers occur in the related IVPLS:
• MC-LAG failure
• Failure of a local SAP
• Failure of a local pseudowire/SDP binding
Note that failure means transition of link SAP/pseudowire to either down or standby status.
