Configuring MAC Pinning on VPLS CE Interface for Logical Systems

date_range 23-Nov-23
arrow_backward
arrow_forward

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 private LAN services (VPLS), you can configure MAC pinning.

This topic describes how to configure MAC pinning on a VPLS customer edge (CE) trunk interface in a logical system.

To configure MAC pinning for VPLS customer edge interface for logical systems:

  1. Configure the interfaces by specifying the encapsulation.
    content_copy zoom_out_map
    [edit interfaces]
user@host# set interfacetype-fpc/pic/port flexible-vlan-tagging
user@host# set interfacetype-fpc/pic/port encapsulation flexible-ethernet-services
  2. Create the logical system by specifying the name and the trunk interface on the logical unit.
    content_copy zoom_out_map
    [edit]
user@host# set logical-systems logical-system-nameinterfaces interfacetype-fpc/pic/port unit logical-unit-number  encapsulation vlan-vpls family bridge interface-mode trunk vlan-id-list vlan-id-numbers
  3. Configure the VPLS CE interface and VPLS routing instance.
    content_copy zoom_out_map
    [edit routing-instances]
user@host# set routing-instance-name  instance-type vpls;
user@host# set routing-instance-name  interface interfacetype-fpc/pic/port
  4. Configure MAC pinning on the VPLS CE interface.
    content_copy zoom_out_map
    [edit routing-instances]
user@host# set routing-instance-name protocols vpls interfacetype-fpc/pic/port mac-pinning
  5. In configuration mode, verify the configuration.
    content_copy zoom_out_map
    user@host# show interfaces
interfaces {
    interfacetype-fpc/pic/port {
        flexible-vlan-tagging; 
		encapsulation flexible-ethernet-services;
    }
}
    content_copy zoom_out_map
    user@host# show logical-systems
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;
                    }
                }
            }
        }
    content_copy zoom_out_map
    user@host# show routing-instances
routing-instances{ 
routing-instance-name  {
    instance-type vpls;
    interface interfacetype-fpc/pic/port;
protocols{ 
    vpls {
        interface interfacetype-fpc/pic/port {
    mac-pinning;
    }
}
}
