Description
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.
Options
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.
