RE: can router L3 port tag the packets as dot1q?

Hi Cyrus,

 

Thanks a lot, does this mean : you can receive the tagged frames, but you
cannot send tagged ?

As I understand from docs, if I configure vlan-range dot1q on a L3
interface, it will receive the tagged frames for the vlan-range which is
configured. But the reply will be untagged.

Is it correct?

Hi Reza,

 U can configure vlan-id on main interface just like sub-interface.However,
hosts connected to same vlan on the switch will not respond to ip address u
configured on router's ethernet interface.

this configuration mainly used for PPPoE or if u wanna make this interface
bridge. It's not as same as sub-interface configuration which is used for
router on a stick scenario.

also take a look at vlan-range dot1q.

HTH,

Hello

is it possible to tag the frames on the physical interface of a router?
(instead of using sub interfaces)

for example does this configuration makes the router ro tag the frames?

interface Ethernet0/0
 ip address 130.1.54.4 255.255.255.0
 no ip mroute-cache
 half-duplex
 vlan-id dot1q 54
 exit-vlan-config
