Friends,
Something interesting and strange while bringing up 3G LTE interface. Here is my configuration to enable wlm0 LTE interface
[size=xx-small][color=inherit][size=xx-small]wirelessmodem[/size][/color] wlm0 {[/size]
[size=xx-small] device ttyUSB4[/size]
[size=xx-small] network airtel[/size]
[size=xx-small] no-[color=inherit][size=xx-small]dns[/size][/color][/size]
[size=xx-small] }[/size]
1). NetworkManager brought up [color=inherit][size=small]the ppp0[/size][/color] interface and got an IP address from the provider. Confirmed from the console logs as well as [color=inherit][size=small]Unix[/size][/color] admin “[color=inherit][size=small]ifconfig[/size][/color] -a” command.
The issue is while executing operational command for “show interfaces”, [color=inherit][size=small]vyos[/size][/color] doesn’t show neither ‘wlm0’ nor ‘ppp0’. Why?

2). I went ahead, ran operation command “show [color=inherit][size=small]ip[/size][/color] route”, [color=inherit][size=small]vyos[/size][/color] added a route for wlm0 that is correct, but it is showing ‘wlm0’ as inactive. Why?
[size=x-small]vyos@vyos:~$ show ip route[/size]

[size=x-small]C>* [color=#1155cc]10.64.64.64/32[/color] is directly connected, ppp0[/size]
[size=x-small]C>* [color=#1155cc]127.0.0.0/8[/color] is directly connected, lo[/size]
- Further to it, I tried from [color=inherit][size=small]unix[/size][/color] admin added default route “route add default dev ppp0”, and able to ping via the ppp0 interface
[size=x-small]root@vyos:/home/vyos# route add default dev ppp0[/size]
[size=x-small]root@vyos:/home/vyos# ping 8.8.8.8[/size]
[size=x-small]PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.[/size]

I know there is some disconnect but [color=inherit][size=small]dont[/size][/color] know where. Could anyone please correct me.
My [color=inherit][size=small]vyos[/size][/color] version is
