Option 60 to get IP from ONT ALTLAB

[victorc7]

Hello,

I bought an RV345 hoping to connect it directly to my RJ45 GPON ONT (ALTLAB) provided by my ISP.

Unfortunately, to get an IP adress and an access to network, you need to send Option 60 to DHCP Server.

This is not supported by this device and there is no plan do support it on WAN port.

Do you know which device would support this option ?

I am planning to get a CBS350, is this device enough to connect to my ISP RJ45 ONT Module?

Thanks in avance,

Best Regards

Hello,

what command are you looking for exactly ? Something like:

ip dhcp class OPTION_60_DHCP
option 60 hex aaabbbcc

?

Thanks for your reply.

Yes I think this command would work.

However, I am not aware of which device support it or not.

 - The particular command is IOS-based and or probably not supported on small business platforms

Hello,

I have tried this command but it seems not to work on ISR 1111.

Whereas, command is accepted by cli :

ip dhcp client option 60 ascii neufbox6

However, dhcp debug detail does not show that this option 60 is used and router cannot get IP adress from ONT.

Here is the config :

ip dhcp class neufbox6
 option 60 neufbox6
!
interface GigabitEthernet0/0/0
 ip dhcp client client-id ascii neufbox6
 ip dhcp client class-id neufbox6
 ip dhcp client hostname neufbox6
 ip dhcp client option 60 ascii neufbox6
 ip address dhcp
 negotiation auto
 spanning-tree portfast

Here is the working config for ISR 1111 :

interface GigabitEthernet0/0/1
 ip dhcp client class-id neufbox_NB6VAC
 ip address dhcp
 negotiation auto
 spanning-tree portfast
end

Thanks
