Message-Id: <1464840894-12697-1-git-send-email-dsa@cumulusnetworks.com> Date: Wed, 1 Jun 2016 21:14:52 -0700 From: David Ahern <dsa@...ulusnetworks.com> To: netdev@...r.kernel.org Cc: David Ahern <dsa@...ulusnetworks.com> Subject: [PATCH net-next 0/2] net: vrf: Improve use of FIB rules Currently, VRFs require 1 oif and 1 iif rule per address family per VRF. As the number of VRF devices increases it brings scalability issues with the increasing rule list. All of the VRF rules have the same format with the exception of the specific table id to direct the lookup. Since the table id is available from the oif or iif in the loopup, the VRF rules can be consolidated to a single rule that pulls the table from the VRF device. This solution still allows a user to insert their own rules for VRFs, including rules with additional attributes. Accordingly, it is backwards compatible with existing setups and allows other policy routing as desired.
