[j-nsp] RE - 6. vlan-id 0 (Bit Gossip)

Hi
Re//

 Experts,
do you know what is the meaning of vlan-id 0?
According to: http://en.wikipedia.org/wiki/IEEE_802.1Q
"VLAN Identifier (VID): a 12-bit field specifying the VLAN to which the
frame belongs. A value of 0 means that the frame doesn't belong to any
VLAN; in this case the 802.1Q tag specifies only a priority and is
referred to as a priority tag"

How would I match this Juniper config:

show configuration interfaces ge-0/0/0
vlan-tagging;
unit 0 {
    vlan-id 0;
    family inet {
        address 1.1.1.1/30;
    }
}

on a cisco device on the other end of the cable where vlan starts from
1?

Instead of configuring a subinterface configure ip under the main
interface:

//r2(config-subif)#encapsulation dot1Q ?
  <1-4094>  IEEE 802.1Q VLAN ID required

 r2(config-if)#ip address a.a.a.a m.m.m.m
  <1-4094>  IEEE 802.1Q VLAN ID required


Thanks,
bit

It works fine for us in practice, though you'll find bizarre statements
to the contrary in the JunOS documentation, such as this in 9.1 and
earlier:

"The following restrictions apply: On a single routing platform, you
cannot configure the same VRRP group on multiple interfaces"

And this in newer versions:

"On a single routing platform, you can assign a unique VRRP group to
only one interface..."

below is the config 

services {

can u suggest what could be cause. i checked in the process running by

To use SSH on Juniper routers, you need to have JUNOS domestic release.
To check this out you may execute the following command?

show version

OR more specific one :) (coz i love junos UNIX like matching style)

show version | match Cryp

The above command will let you know that you are running with a crypto
package or not. If not then you have to get JUNOS domestic release

Completely expected if you're running the non-domestic version of the
JunOS software.

You need to install the domestic version
(jinstall-*-domestic-signed.tgz) which has ssh support.

Are you using the Worrldwide junos image (no ssh) or the domestic junos

Hi

AFAIK, basically a unit 32767 is created implicitly when "vlan-tagging"
is enabled to pass untagged control traffic (like STP, LACP ... etc).
When a unit with vlan-id 0 is configured, this unit itself is used to
send the control traffic. So the unit 32767 then gets deleted.



ge-1/1/0                up    up
ge-1/1/0.1              up    up   inet     1.1.1.0/31
ge-1/1/0.2              up    up   inet     2.2.2.0/31
ge-1/1/0.32767          up    up

Some attached devices may not accept 802.1q-tagged frames, and therefore
can reside only in VLAN 0.
Conversely, some devices may accept only tagged frames, requiring that
even frames in VLAN 0 be tagged. So JUNOS is providing you the way to
deal with such boxs.. :D

The range for valid VLAN IDs on Cisco kit is 1 to 4094 with VLAN 1 being
the default VLAN. I suspect VLAN 1 might be what you are talking about
when they refer to VLAN 0.
However, to muddy the water, Cisco's documentation for the 3750 reveals
that there IS a VLAN 0 - but only when you're using VOIP

Your configuration is missing "vlan-tagging"
Is behaviour remains the same if you add "vlan-tagging" under interface
configuration.
