Up till Friday the 8th of May in one of our remote locations we had BT as ISP and the 877W was working fine.
We change the provider to âBe Un limitedâ and since then we are unable to configure the 877W.
Below is a guide to Be* members wanting to use a 3rd party modem/router.
Who is this guide for?
For all Be* members configuring and wanting to use a 3rd Party Modem to connect to our broadband service.
âBe* technical support can only provide help for the Bebox and support for connection/speed problems to customers using the BeBox. It is necessary for the Bebox to be connected and the issue reproduced before raising a ticket or contacting support.â
In order to use a 3rd party modem it has to be compliant with ADSL2+ service (has to support g.dmt.992.5 Annex A/Annex M(for BE* Pro members only) modulation)
If you have any such device that you feel more comfortable with, you will need to input the
1) vci=101 and vpi=0.
2) ADSL bridging should enabled (as per RFC 1483).
3) When configuring the WAN (DSL interface), you would get an option asking whether your ISP authenticates with user/pass or not - you have to choose NO in there, as we require no username and/or password for access to our network.
4) Connection type is IPoEoATM.
5) Multiplexing is LLC-based. If you are able to choose the LLC type it should be set to SNAP.
This should be sufficient for you to set up any 3rd party modem with our service. For more information in regards to third party modems, please refer to our forum where you can find solutions and opinions from fellow-members using third party hardware.
Please note that our hotline agents do not support third party hardware and can only give settings provided above.
The old configuration of the 877W is:
boot system flash c870-advipservicesk9-mz.124-6.T2.bin
no ip address
no ip mroute-cache
no atm ilmi-keepalive
dsl operating-mode auto
interface ATM0.1 point-to-point
no snmp trap link-status
dialer pool-member 1
protocol ppp dialer
no ip address
ip nat outside
dialer pool 1
no cdp enable
ppp authentication ms-chap callin
ppp chap hostname [email protected]
ppp chap password 7 xxx
ip route 0.0.0.0 0.0.0.0 Dialer0
Can somebody help me to configure the 877W to work with the new ISP?
I also attach a user.ini file that is the current configuration of the new ISP's Modem Router.
Have you tried "atm route-bridged" as well ?
Please do not low rate posts without a valid reason.
RFC1483 bridged means that ethernet frames are bridged over the ATM/ADSL.
The router has to behave as a bridge with one interface that is the lan interface and one that is the ATM.
The specificity of 877 is to use an SVI Vlan1 interface instead of eth0/0 of older routers.
I guess you would like to access the device remotely so you need IRB integrated routing and bridging
bridge 1 protocol ieee
bridge 1 route ip
! these for all FE ports
! that are members of vlan1
no ip addr
int atm0.1 point-to-point
no ip addr
! virtual L3 interface for bridge-group 1
ip address dhcp
ip route 0.0.0.0 0.0.0 bvi1
I'm not sure the config of BVI is correct for you ISP.
if the ios image allows to use a second vlan (vlan2)
you can have vlan2 configured as ip nat inside and BVI as ip nat outside
you can associate some FE port to vlan2 as:
switchport mode access
switchport access vlan2
for RFC1483 bridged
for bridging on vlans on 877
Hope to help
