From 0b8c01b4058eff19e88da4dfa0f598a9c24a8d3b Mon Sep 17 00:00:00 2001 From: Benjamin Poirier Date: Mon, 11 Dec 2023 09:07:15 -0500 Subject: [PATCH] bridge: vni: Fix duplicate group and remote error messages Consider the following command with a duplicated "remote" argument: $ bridge vni add vni 150 remote 10.0.0.1 remote 10.0.0.2 dev vxlan2 Error: argument "remote" is wrong: duplicate group The error message is misleading because there is no "group" argument. Both of the "group" and "remote" options specify a destination address and are mutually exclusive so change the variable name and error messages accordingly. The result is: $ ./bridge/bridge vni add vni 150 remote 10.0.0.1 remote 10.0.0.2 dev vxlan2 Error: duplicate "destination": "10.0.0.2" is the second value.
