[c-nsp] Possible to trunk over Serial or DSL?
Hi all. I'm trying to find a possible way to run dot1q tags over serial and/or dsl interfaces. I could trunk over E1's on my old Riverstone kit without a problem, but I can't find a way to do it with a Cisco box. Is this possible?

Cisco can do *bridging* over E1, which might or might not do dot1q if tagged packets are coming in via the to-be-bridged LAN interface. Might be worth a try :-) If you want to do routing via those E1s, and have separate virtual routers (what is dot1q to switches), take a look at either FrameRelay encapsulation on the E1, or MPLS with VRF/Layer3 VPNs. Or MPLS with Layer2 VPNs.

Re: [c-nsp] Possible to trunk over Serial or DSL?
Hi Gert. Thanks. Basically what I'm trying to do is run subinterfaces, with each of those subinterfaces in a separate vrf. So while I can have fa0/1.10 and fa0/1.20 in different vrfs on the same box, I would like to be able to do the same over Serial and/or ADSL. I have been able to do this with an old Riverstone so technically it should be possible.

Hi Darren, you wrote: I'm trying to find a possible way to run dot1q tags over serial and/or dsl interfaces. I could trunk over E1's on my old Riverstone ADSL doesn't know about VLANs, because it's based on ATM. But you could use different VPI/VCI-Pairs to seperate the traffic. Some snippet for this: interface ATM0 no ip address ! interface ATM0.1 point-to-point pvc 1/32 pppoe-client dial-pool-number 1 dial-on-demand pvc 2/32 pppoe-client dial-pool-number 2 dial-on-demand But in VDSL you can use VLAN subinterfaces like FastEthernet0/0.10 because it's based on Ethernet. Both things have to be configured also in the DSLAM on the other end of the DSL line and are terminated there. You cannot tunnel VLANs this way to another DSL line. -- Regards Thomas ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

On an E1, you can use frame relay encapsulation, and map different DLCIs to subinterfaces (I do not have a configuration ready to share, but cisco docs should have plenty of examples). On ADSL, this is harder, as you do not really have a transparent HDLC stream between both ends - it might work running multiple PPPoE sessions, but that's not properly supported on Cisco CPEs, and would be ugly anyway (and whether it can work at all depends on how this specific ADSL circuit is implemented end-to-end). MPLS-over-PPP might be an option here. I have been able to do this with an old Riverstone so technically it should be possible. It is, you just need to tag the frames in a way to make the other end recogize them - and that's basically what a frame relay DLCI does. (Of course Riverstone could use whatever they like, as an E1 is really quite transparent here regarding frame contents and interpretation...) gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany g...@greenie.muc.de fax: +49-89-35655025g...@net.informatik.tu-muenchen.de pgpxvATmsVNAR.pgp Description: PGP signature ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

For serial interfaces you can run frame-relay encapsulation and map VLANs to PVCs. For DSL, if you control the DSLAM you can do something similar mapping VLANs to ATM VP/VCs. Other solutions include tunneling, pseudowire, etc. -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
