Hoi Chinmaya, I'm not quite sure I understand your question. You can advertise prefixes with BGP (FRR or otherwise). There's many ways of doing this, for example by means of a route-map that captures attributes of the route in the RIB and then deciding to advertise. I also don't quite understand what the linux-cp/linux-nl plugins have to do with this type of advertisement. However, before FRR will pick up the prefix you set manually in VPP, you'd have to propagate that prefix as well to the LInux side so that FRR can pick it up.
Matt: this is one of those places where having, in general, a sync from VPP -> Linux would be useful. Chinmaya: Currently, the plugins do not propagate state changes from VPP into Linux. I have a gerrit out for that ( https://gerrit.fd.io/r/c/vpp/+/33709) but it only propagates MTU, admin-state and IP addresses, not routes or other info. In lieu of that, you must add routes that you added in VPP, also to Linux (ip route add <...> before they can be picked up by FRR). groet, Pim On Mon, Sep 20, 2021 at 11:17 AM Chinmaya Aggarwal <chinmaya.agar...@hsc.com> wrote: > Hi, > > I am using linux-cp and linux-nl plugins to install BGP routes in VPP and > it is working fine for us.
