2017-10-05Distributed Virtual Router SupportNeale Ranns2-0/+6
A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

2017-09-05PUNT socket: External control plane processes connected via UNIX domain sockets.Ole Troan3-11/+555
An external (to VPP) process can register (over the VPP binary API) to receive control plane packets over a UNIX domain socket. The packets are prepended with a packet descriptor containing meta-data (if_index of interface, etc). Currently only UDP is supported. The socket supports sending of packets/frames as well. The sent packet is prepended with a descriptor, telling VPP to route the packet (via ip4-lookup, ip6-lookup) or as an pre-formed Ethernet frame that is sent directly to interface-output. The intended use case for this is for an external DHCP client or a RIP implementation. New configuration option: punt { socket <socket path> } To register use the punt_socket API message. TODO: - Add support for pre-routing. I.e send L3 packet to given TX interface, but do ARP/ND (ip[46]-rewrite) - Add test scripts - Support for abstract names (starting with \0) - Add rate limiting (COP) - Support for other protocols, e.g. IPv6 ND Change-Id: I4a0afc8020deebb3d9d74686dde694ee5bcb8d0f Signed-off-by: Ole Troan <ot@cisco.com>

Paths are given a preference, lowest value is 'best'. Only paths that are up are up contribute to fprwarding - that's unchanged. What's new is that of the path's that re up only those that have the best preference contribute. A poor man's primary and backup. It's not true primary/backup function because the FIB must converge before the lower preference paths are used.
