suppress_prefixlength in ip rule is not working

[tramchamploo]

ip rule add table main suppress_prefixlength 0

The command above is not working and adds a rule without suppress_prefixlength.

ip rule

not showing the suffix.
This command is critical to implement custom routing if you want to reuse the old rules.

Requires a 3.x kernel or higher. What router model do you have?

 

[tramchamploo]

ac68u linux 2.6. Also lack of wireguard support. Is a kernel update possible in a future release?

No, not possible.

In theory it is possible as other third party firmwares are running Kernel 4.4 for Broadcom Northstar e.g. Asus AC68U but in practices very difficult without having access to the closed source Broadcom code

 

[egc]

But you can maybe do it the old fashioned way and just copy all local routes to the other tables

Flat out impossible without the full source code.
