You are configuring a trunk interface on an MX Series device and want to ensure that any
outgoing frames associated with VLAN 100 are transmitted as untagged frames. Which
configuration will achieve this objective?
A.
vlan-id 100
B.
routing-interface irb.0
C.
vlan-id-list [100]
D.
native-vlan-id 100
http://www.juniper.net/documentation/en_US/junos12.3/topics/reference/configuration-statement/native-vlan-id-edit-interfaces.html
Note: As per 12.3 Ethernet Interfaces Configuration guide, native-vlan-id enables the tagged interface to accept untagged frames. However, when native-vlan-id is configured, VLAN ID is popped in egress as long as the VID in the outgoing frame matches the native-vlan-id.
I believe D is the correct answer
Isn’t it, could anyone advice?
D
By definition the native vlan is the untagged one
B is Wrong
routing-interface irb.0 has nothing to do with TRUNK.
