| [Config] Cisco 1921 and HWIC-1VDSL Hi, I remember seeing some old posts about this, and I am hoping to configure the router to run my BT Infinity service.
I am brand new to Cisco, but have managed to configure the router to work with the supplied VDSL2 modem, using a forum members config..
I have sync/ Showtime on the VDSL2 card, (sh controller vdsl 0/0/0) so this is to let others know that the combination should work.
A "newbe" question, does the interface for router to office network still need to be configured as VLAN, as it has to be to work with the supplied modem.
I would like to try to solve this issue myself, but an answer to the above question would help.
Thanks. |

I'm guessing you're trying to do a VPN tunnel between your 1921 and the office? If so,
then generally no, VLANs have NOTHING to do with VPN.
May help to explain what you're trying to do, and provide a copy of your current config
for review.

What i'm trying to do is replace the service provider's router and notoriously unreliable VDSL modem with a Cisco 1921 and HWIC-1VDSL card. The router will then connect to my Gig Switch and small office setup.
This is purely for non-professional use, and I have taken this route because I like to challenge myself, and like to learn new skills.
Here is the config, I know it is a mess, I have cut and added things from the original config which worked with the IP's modem.

The output from the IP's supplied modem demanded a router configured for PPPOE, in my ignorance, I thought that was what VPDN was about. I now know it's about VPN dial-up.

Can you also provide a "show inventory" from the router?
Which interface are you planning for your LAN interface, just out of curiousity?
From the looks of it, Gi0/0 was to form a trunk to your LAN interface, with
a subint on Gi0/0.1, Gi0/1 was to be the WAN interface, and I'm not sure where
eth0/0/0 came from, unless you have a ethernet WIC card present.
Right now I'm guessing Dialer1 is the interface you're going to use for your
BT service?

Here is the sh inventory:

NAME: "VDSL over POTS supporting VDSL2 on Slot 0 SubSlot 0", DESCR: "VDSL over POTS supporting VDSL2"
PID: HWIC-1VDSL , VID: V01 , SN: FOC151311CY
I'm not sure where ethernet0/0/0 came from, I think it appeared on installation of the HWIC-1VDSL module, which I configured with the basic configuration in the module's
manual, although I have since taken some out, pim, etc.
I had set up only the sub-interface 0/0.1 as the lan interface, and it worked correctly with the dialler as shown on the BT infinity service, which I would use for the module if possible.
This was the set-up using the supplied external vdsl modem, and WAN interface gi0/1.
I know it is running before I can walk, but what I hoped to do was use either the VDSL module or the WAN interface,
but it's not necessary, I would prefer to use the VDSL module now I have bought it!
Gi0/0 was indeed going to be the LAN interface, but the config I copied specified a sub interface, I thought that was necessary to get the PPPOE to work.
Here's the int brief as well:
isco1#sh ip int brief

Just to prove the point, I have removed the HWIC-1VDSL module, and eth0/0/0 has gone:

Never seen that before... and I don't own a 1921 / WIC card to test myself.
Should be able to crib a DSL config from the forum FAQ or from Cisco to start.
If you need VLANs on your LAN, then keep what you have on Gi0/0.1, otherwise,
it doesn't really serve a functional purpose.
Other thing I can think of is if you're getting your IP from your ISP dynamically, you don't need
this block
ip route 0.0.0.0 0.0.0.0 Dialer1
ip route 0.0.0.0 0.0.0.0 217.32.142.104
Try that and let us know.

He isn't running any VLANs. A single subif configured as "native" means no packets on that interface are being tagged. Unless there's a lot more going on here that isn't being explained, there's no reason to configure G0/0 like that -- other than "because I can".
The configuration using the provider modem is using a private address and no PPPoE. This suggests NAT and PPPoE are occuring at the modem. Someone will have to figure out how the modem is configured and setup the E0/0/0 interface to match. It should be pretty much exactly the same as with an ADSL ATM interface. |

Ok. I got it slightly backwards...
G0/0 is your LAN. There's still no reason to configure it that way. (as far as the info has been provided)
G0/1 goes to the ISP modem. It gets an address by dhcp and runs pppoe. (?)
If E0/0/0 is the VDSL link replacing the modem, it should be configured the same as G0/1. Thus, "ip nat outside" and "ip address dhcp".
Only one default route is needed. "ip route 0.0.0.0 0.0.0.0 217.32.142.104" is not needed, and likely isn't even being used. The interface route will get everything rolling, but with the local VDSL interface, it won't be necessary as the interface coming up will cause it to "dial". (or it does for ATM based DSL. won't hurt either way.) |

kudos:1 | »www.cisco.com/en/US/docs/routers···wic.html gives details on how to configure the HWIC-1VDSL.
cramer  is (of course!) completely correct about the ethernet PTM interface.
I have one of the combo ADSL/VDSL EHWIC-VA-DSL-A cards in the office 1921 and it is switchable from ATM to PTM. Currently it is still on ADSL but I'm hoping to make the switch to BT Infinity VDSL in the new year and get a chance to configure the VDSL interface. I'll post back with any results. |

Hi, Guys, thanks for the replies.
I copied the Nat and dhcp settings from g0/1 to the vdsl card, and have tried out the suggested settings in the config from Cisco for the card, with no result.
Unfortunately there are probably things in the Cisco config that need changing, but I have insufficient knowlege to do.
Here is a section:

Could someone please explain what a "Host dirt" is, I am aware that the Ip address after it is the last one available, is this important?

ip route 223.255.254.254 255.255.255.255 2.7.0.1
Do you see the ip address of the e/0/0/0 in this case?
If I connect VDSL I get showtime synch, and the card goes admin and protocol up, and I can ping the ip of e0/0/0 but no further.
I have tried to research "pim" and get the impression it's a multi-protocol setting, but I'm unsure of that, and also the many static ip routes.
Sorry about this, but there's no rush, I'm unlikely to try again until Jan 2012.
Many thanks for the help thus far guys!

| PIM == protocol independent multicast (multicast routing) I'm not sure why it's enabled on an Internet link.
You still haven't provided any information on how the ISP provided modem is setup.
If you're running PPPoE, then the ip address of the vdsl interface is meaningless. Check that dialer1 is active and has an address...

Dialer1 is up, line protocol is up (spoofing)

BT Infinity is supposed to be used with the supplied modem and is not a 'wires only' service. There is therefore currently no official guidance for configuration of third party VDSL modems and it is most definitely not supported.
There is potentially helpful information on the Draytek UK website which suggests that the 'WAN VLAN ID should be set to 101': »www.draytek.co.uk/support/kb/kb_···tup.html.

kudos:5 | So that would be E0/0/0 at a default configuration (no ip, etc.) and an "E0/0/0.101' subif configured for dot1q and pppoe.
Interesting. I shall have to experiment with this using my 1721. (the vlan + pppoe, not VDSL) |
|
| Looks like the way to go.I can't find out any more about the provided modem, only that it's being hacked and modified to provide stats!
Here's a copy of the Draytec page:
Click on [WAN] > [Multi-VLAN] and set the settings as shown. With BT Infinity the WAN VLAN ID should be set to 101:
Apparently BT have dropped the enforcement to use their modem from the T&Cs, I'm not surprised after what the BT engineer who brought my second replacement told me "These are Sh*te!"
I will try a vlan setup on e0/0/0 as well.
Can somebody please tell me what "ip host dirt" means? |

| That is correct. However, you still have a ton of junk making things not work.
• Routing is disabled. ("no ip routing") It will not forward packets from interface to interface in that mode.
• CEF is disabled. ("no ip cef") This will *significantly* reduce it's forwarding rate.
• Route-cache is disabled. ("no ip route-cache" under every interface.) This will absolutely kill throughput.
E0/0/0.101 is not an IP interface. It should not have any IP configuration set... no ip address, no nat, no adjust-mss.
Di1 is not a NAT'd interface... it's neither inside nor outside. As such, when routing is enabled, you will be sending traffic into the internet using private addresses. This, obviously, will not work.
BUT, you're getting an address, so you've gotten that part of the magic figured out. |
