Hello @maimun.najib , try to set interface-cache option, it should save some resources on interface recreating (reconnecting sessions)
set service pppoe-server ppp-options interface-cache 3000

hi @Dmitry , in my vyos there is no interface-cache option, I’m using VyOS 1.3.0-rc5

Hello @maimun.najib , I believe it should be available in rc6, or you can test the latest 1.4 rolling

5

is version 1.4 rolling already recommended for production as a distribution router?

6

1.4 can contain some bugs, as 1.3 rollings, but most of the features are already stabilized. We can recommend for production only TLS 1.2.8. You can also patch your 1.3 RC5 manually, just follow this feature request ⚓ T3405 PPPoE server unit-cache

7

how do i get the LTS version 1.2.8 ?

8

Hello @maimun.najib you can build LTS version from a source code - VyOS Project · GitHub
Also ready to deploy 1.2.8 LTS version is part of the software and support subscriptions listed here
