Cisco 8194G Issue when create WAN-1 PPPOE Dialer 1 profile and Integrated Cellular 0 Interface like WAN-2

[plussier1]

Hi

Before i add the Dialer 1 configuration for WAN-1 PPPOE internet access the Cellolar 0 interface working well.

When I add the Dialer 1 Interface Config and I plug it to the DSL modem, now the primary internet WAN-1 (PPPOE) is working but

look like that something conflict with the interface cellular 0 because now, WAN-2 doesn't work even if the WAN-1 interface Is down.

Please see the Part of the Configuration bellow.

I think they have conflict between Dialer-Group ?

How can I resolve that ?

Hello,

post the full config if possible. What is your dialer interface bound to ? What interesting traffic do you have defined in the crypto map ?

Please see the attached configuration file.

At the moment this router is in operation on WAN-1 and everything is working.

Short Story, At the office with first configuration everything was working on cellular 0 interface and tested.

On Site We add the Dialer-1 interface configuration on the router for the WAN-1 PPPOE ADSL Internet access.

When the configuration was finish and wan-1 connected on ADSL Modem the router switch from Backup WAN-2 to Primary WAN-1 without issues.

Now the issues is when the WAN-1 (PPPOE) adsl connexion goes down, the Backup WAN-2 integrated LTE cellular 0 interface doesn't work anymore.

I did the test on site with a laptop plogged to the Router to generate trafic on Internet and when I unplug the WAN-1 connexion, WAN-2 doesn't work, cellular o interface doesn't come up, but as soon I plugged back the WAN-1 everything working again.

I saw that I use Dialer-Group1 on Both cellular 0 and Dialer 1 interface.

Is there a way that cause the conflict that now the cellular 0 doesn't come up anymore ?

Let me know.

Thank You !

Hello,

the config looks good as far as I can tell. The only thing I am worried about are the permanent static routes which are not tracked. Can you try to remove those ?

no ip route 195.46.39.39 255.255.255.255 Dialer1 permanent
no ip route 208.76.50.50 255.255.255.255 Cellular0 permanent
no ip route 216.146.35.35 255.255.255.255 Dialer1 permanent

Hi Georg,

I remove the 3 permanent route but nothing change.

I need for sure the 2 Permanent route

ip route 195.46.39.39 255.255.255.255 Dialer1 permanent

ip route 216.146.35.35 255.255.255.255 Dialer1 permanent

to force the IPSLA to pass by the Dialer 1 interface to check the connexion status.

Do you have an other idea why the cellular 0 interface don't want to go up anymore ?

Thank You !
