Hi , I think, this topic has been discussed in few of the earlier questions, but still I could not find a one that gave a workable solution in totality. We are trying to write a BGP application which hosts BGP peering sessions, using VPP as a dataplane entity.
We tried following few options with issues mentioned below. I am also attaching an image that we are trying to achieve. 1) Tried to clone VPP sandbox code for vpp router plugin. But, vppsb repo does not seem to be available in the following path anymore. https://gerrit.fd.io/r/vppsb Is there a place where I can get this code ? Or Is this obsoleted one ? 2) If vppsb is obsoleted, is there an alternative that works well for this. We tried punting approach by doing a. set punt tcp b. ip punt redirect add rx Interface/7/0.100 via 1.1.1.1 tapcli-0 However, here, we are seeing an ARP being sent from vpp-veth-ifc to host-veth-interface and it is not able to resolve the ARP. The redirect is getting triggered from VPP, but it is not reaching the host due to the ARP issue. Is there anything that we need to do for this ? Also, in this approach, the reverse path from vpp-host to the external box, how will it work ? The punt redirect config that we added, will it work for reverse path as well ? Please help us here as we are kind of stuck with what approach we need to take ? ( we want to avoid the VPP-TCP-stack for the time being, as it will be more effort to integrate our BGP app with VPP-TCP-stack,i.e VCL framework ). -- Thanks & Regards, Murthy
