Backup PPPoE connection

RouterOS Scripting
1

Refer to http://forum.mikrotik.com/t/backup-pppoe-connection/5878/1

I have 2 PPPoE connections on different interfaces. As soon as my primary connection drops, it should connect on my secondary interface.

The proposed solution under refered thread does not work - I cannot work with the IP address of the interface to determine the PPPoE connection status, this IP is fixed…

My complete script is as follows
:global pppoe1-name ADSL_Connection
:global pppoe2-name ADSL_Backup

– The following statement works ONLY if there is an IP assigned. If not, it bombs out
:local pppoe1-ip [ /ip address get [/ip address find interface=$pppoe1-name] address]

– If the connection is not established, the rest DOES NOT execute ; not even this log info messages
:log info $pppoe1-ip

:if ([ :typeof $pppoe1-ip ] != nil ) do={
/interface pppoe-client disable [/interface pppoe-client find name $pppoe2-name]

:log info ("Conected to " . $pppoe1-name)

} else={
/interface pppoe-client set [/interface pppoe-client find name $pppoe2-name] add-default-route=yes
/interface pppoe-client enable [/interface pppoe-client find name $pppoe2-name]

:log info ("Conected to " . $pppoe2-name)
}



Any other to check if a connection is active? I have also tried the “get Status” on the pppoe-client interface, doesn’t work.

Just basically need to check if the connection is active or not… The IP-assigned route does not work, any other way to see if a connection is up / down?

3

IP assigned route does not work?

You mean add a route for a specific IP the use netwatch. Does work, why not for you?

I use netwatch for watching my other connections, but in this scenario it won’t work due to the fact that the backup line is not always connected. I know I can have a watch on my primary line, but this can also cause havoc…

All I need is to get the STATUS of a pppoe-client connection. On the Interface page, whether is is R (Running) or not… I cannot find any script that can return the ‘Status’ of an interface.

How can this cause havoc?

Like what?

:if ( [ /interface pppoe-client get PPPoE_Out running ] = true ) do={ :log error popsicle}
