I apologize with all the list. I supposed that the Pim van Pelt plugins code was commited to the main repository and I didn't compiled/configured it.
Now I've compiled the Pim's plugins and switched the config of vpp to the Pim's one and all works fine. I've to study and practice a lot before ask again. :) Sorry for the bothering on silly issues. Thanks. Ciao. Fabio. Il 26 Maggio 2022 17:02:56 CEST, Fabio Bizzi <fabiofo...@bizzi.org> ha scritto: >Hello, > >I'm in trouble with VPP and frr/static routing. >My setup is the following: > >- O.S.
