From fe89aa6b250c1011ccf425fbb7998e96bd54263f Mon Sep 17 00:00:00 2001 From: Mahesh Bandewar Date: Thu, 26 Oct 2017 15:09:25 -0700 Subject: ipvlan: implement VEPA mode This is very similar to the Macvlan VEPA mode, however, there is some difference. IPvlan uses the mac-address of the lower device, so the VEPA mode has implications of ICMP-redirects for packets destined for its immediate neighbors sharing same master since the packets will have same source and dest mac. The external switch/router will send redirect msg. Having said that, this will be useful tool in terms of debugging since IPvlan will not switch packets within its slaves and rely completely on the external entity as intended in 802.1Qbg.
