<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US>I’d like to connect two CE-switches that
speak 802.1q tagged vlans (1untagged, 5 and 10 tagged) with each other over a MPLS
core.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Mpls always wants to use vlan-tag it
receives on the port of the PE router to identify individual vll or
vpls-services.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>How can I turn this off? I simply want to
carry all the traffic including the tags over the cloud to the edge router.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Network map:<br>
<br>
<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Customer-Switch-1(CE) === vlan tags 1, 5
and 10 ==== Netiron-XMR-1(PE) -----MPLS CORE---- Netiron-XMR-2-(PE) === vlan
tags 1, 5 and 10 === Customer-Switch 2 (CE)<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’m using Netiron XMR routers and am
willing to use either vll or vpls – it doesn’t really matter.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’ve already tried to configure the
port as untagged on the XMR but the result is that the untagged default vlan
works but the vlan 5 and 10 are getting lost.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>It would be simple to configure multiple VPLS
end-points – one for each vlan – but I don’t want to
configure each vlan the customer uses on his customer switch on my MPLS core?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><br>
Example:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>vpls VPLS-between-customer-switches max-mac
1024<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> </span>vpls-peer 10.10.10.2<o:p></o:p></p>
<p class=MsoNormal> vpls-mtu 1522<o:p></o:p></p>
<p class=MsoNormal> vlan 1<o:p></o:p></p>
<p class=MsoNormal> <span lang=EN-US>untagged ethe 1/3<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> vlan 5<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> tagged eth 1/3<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> vlan 10<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> tagged eth 1/3<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>[“vc-mode tagged” didn’t
help]<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>It would also be simple if the CE-device
was able to use double tagging but unfortunately it doesn’t </span><span
lang=EN-US style='font-family:Wingdings'>L</span><span lang=EN-US> In my case
the CE-device is a simple HP procurve switch that has several tagged vlans and
the untagged default vlan configured on one port.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’m thinking on something like:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>vll VLL-between-customer-switches 10001<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> vll-mtu 1522<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> vll-peer 10.10.10.2<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> untag e 1/3<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>But this doesn’t work </span><span
lang=EN-US style='font-family:Wingdings'>L</span><span lang=EN-US> as all tags
are getting lost.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>What’s the optimal way to achieve the
transport of all 802.1tagged vlans without configuring them on the MPLS core?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Thanks guys<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Gunther<o:p></o:p></span></p>
