Bridging between two VWIC-1MFT-G703 cards

Hi All,

Need a question answered urgently if someone has a moment please?

2801 with two g703 cards. Each 2mb cct goes to different sites, each site has a a 2811 on the end, again with G703 cards:

2811--2mb--2801--2mb--2811

The 2811's are running EIGRP, nothing on the 2801

What I'm trying to achieve is put the two cards on the 2801 that sits in the middle, into bridging mode. Seems a doddle according to all the command references!! Won't play though.

Basic config has;

no ip routing

int s0/2/0:1

bridge-group 1 spanning-disabled

bridge-group 1

int s0/3/0:1

bridge-group 1 spanning-disabled

bridge-group 1

I've also tried a whole load of orther commands such as bridge irb, bridge crb, bridge 1 bridge ip, added and removed int BVIx etc etc

Any ideas please?

Many Thanks

Ali

This 1-port WIC card allows the co-existence of ADSL and ISDN on the same local loop and provides high-speed ADSL digital data transfer between a single customer premises equipment (CPE) subscriber and a central office.

err - no!!

I think you may have replied to the wrong post. This card is a multi-flex WAN card

Hi Ali,

If I'm not mistaken you are trying to encash the Drop-n-Insert feature of the W1C2MFTs.

I guess this link should be of quite a big help for you.

Hope that it helps.

Please let us know in case if this doesnt meet your requirements.

Re: Bridging between two VWIC-1MFT-G703 cards

Hi,

This is a sample configuration for your information.

card type t1

controller T1 0

framing esf

linecode b8zs

tdm-group 2 timeslots 13-24

!

controller T1 1

framing esf

clock source internal

linecode b8zs

tdm-group 3 timeslots 1-12

!

connect dfw1 T1 0 2 T1 1 3

The following shows a configuration for the Cisco 2651 router in Figure 2:

controller T1 0/0

framing esf

clock source internal

linecode b8zs

channel-group 0 timeslots 13-24

!

interface Serial 0/0:0

ip address 209.165.200.253 255.255.255.224

The following shows a configuration for the Cisco 3640 router in Figure 2:

controller T1 0/0

framing esf

linecode b8zs

channel-group 2 timeslots 1-12

!

interface Serial 0/0:0

ip address 209.165.200.252 255.255.255.224

Please note the following:

?The tdm-group 2 timeslots 13-24 command defines drop-and-insert capability by setting the time slots from each T1 that will be used in the digital cross-connection.

?The connect dfw1 T1 0 2 T1 1 3 command activates the drop-and-insert digital cross-connection between the T1s. The dfw1 parameter is a name for the cross-connection; the name can be any word, any number, or any series of letters.

?You can verify drop-and-insert connections by using the show connection all command.

Verifying Controller Settings

The show controller t1/e1 command displays the status of T1 or E1 controllers and displays information about clock sources for the ports:

Router#show controller t1

T1 0 is up.

Applique type is Channelized T1

Cablelength is long gain36 0db

No alarms detected.

alarm-trigger is not set

Version info Firmware: 20011109, FPGA: 15

Framing is ESF, Line Code is B8ZS, Clock Source is Line.

Data in current interval (708 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

T1 1 is up.

Applique type is Channelized T1

Cablelength is long gain36 0db

No alarms detected.

alarm-trigger is not set

Version info Firmware: 20011109, FPGA: 15

Framing is ESF, Line Code is B8ZS, Clock Source is Internal.

Data in current interval (708 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

Verifying Drop-and-Insert Configuration

To verify drop-and-insert configuration, enter the show connection all command.

Router#show connection all

ID Name Segment 1 Segment 2 State

============================================

1 dfw1 T1 0 02 T1 1 03 UP

I think all it needs is this "bridge 1 protocol ieee".

Teddy/Guys,

Thanks for all your suggestions. Unfortunately, due to time constraints we had to go to a routed solution, but a TAC engineer managed to solve it.

As we are both bridging and routing on the two spoke routers, we needed bridge irb and int BVIx

I'm a bit pushed for time here, but if anyone would like to the configs, reply here and I'll paste them

Agin, thanks for your time and input
