no-local-switching (VLAN)

Syntax

Hierarchy Level

Description

Specify that access ports in this VLAN domain do not forward packets to each other. You use this statement with primary VLANs and isolated secondary VLANs. You can also disable local switching on both customer edge (CE) and VPLS edge (VE) mesh-groups. Access and core-facing interfaces are included in the system-generated CE mesh-group and VE mesh-group, respectively. Traffic originating on access interfaces, including EVPN tunnel traffic, will be flooded only to core-facing interfaces. Traffic originating on core-facing interfaces, including EVPN tunnel traffic, will be flooded only to access interfaces.

Note:

(MX80, MX104, and the 16x10GE MPC, MPC1, or MPC2 on MX240, MX480, MX960, MX2010, and MX2020 only) If you configure the no-local-switching command at the [edit bridge-domains bridge-domain-name] hierarchy level, it might not prevent multicast traffic from being forwarded between the CE-facing interfaces of the bridge domain. Broadcast, unknown unicast, and known multicast traffic does not exhibit this behavior.
