family bridge (GRE Interfaces)


Hierarchy Level


Configure the bridge domain family on GRE interfaces. To enable Layer 2 Ethernet packets to be terminated on GRE tunnels, you must configure the bridge domain protocol family on the gr- interfaces and associate the gr- interfaces with the bridge domain. You must configure the GRE interfaces as core-facing interfaces, and they must be access or trunk interfaces. To configure the bridge domain family on gr- interfaces, include the family bridge statement at the [edit interfaces gr-fpc/pic/port unit logical-unit-number] hierarchy level.


interface-mode—Specify the type of VLAN tagging on packets that the interface accepts.

access—Configure a logical interface to accept untagged packets. Specify the VLAN to which this interface belongs using the vlan-id statement.

trunk—Configure a single logical interface to accept packets tagged with any VLAN ID specified with the vlan-id or vlan-id-list statement.

core-facing—Specify that the VLAN is physically connected to a core-facing ISP router and ensures that the network does not improperly treat the interface as a client interface. When specified, the interface is inserted into the core-facing default mesh group where traffic from pseudowires that belong to the default mesh group is not forwarded on the core-facing link.

vlan-id number—Individual VLAN IDs separated by a space.

vlan-id-list vlan-list—Starting VLAN ID and ending VLAN ID in an inclusive range. Separate the starting VLAN ID and ending VLAN ID with a hyphen.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
