A MAC move occurs when a MAC address frequently appears
on a different physical interface than the one it was learned on.
Frequent MAC moves indicate the presence of loops. To avoid loops
across interfaces in virtual switches in logical systems, you can
configure MAC pinning. A set of logical systems within a single router
can handle the functions previously handled by several small routers.
This topic describes how to configure MAC pinning for all pseudowires
of the VPLS routing instance for logical systems.
To configure MAC pinning for all pseudowires of the VPLS
routing instance for logical systems:
- Configure the interface by specifying the encapsulation.
[edit interfaces]
user@host# set interfacetype-fpc/pic/port flexible-vlan-tagging
user@host# set interfacetype-fpc/pic/port encapsulation flexible-ethernet-services
- Create the logical system by specifying the name and the
trunk interface on the logical unit.
[edit]
user@host# set logical-systems logical-system-name interfaces interfacetype-fpc/pic/port unit logical-unit-number encapsulation vlan-vpls family bridge interface-mode trunk vlan-id-list vlan-id-numbers
- Configure the VPLS routing instance.
[edit routing-instances]
user@host# set routing-instance-name instance-type vpls
user@host# set routing-instance-name interface interfacetype-fpc/pic/port
user@host# set routing-instance-name protocols vpls mac-pinning
- In configuration mode, verify the configuration.
