Subject: [PATCH iproute2] route: label externally offloaded routes
Date: Sat, 7 Mar 2015 22:15:35 -0800 [thread overview]
Message-ID: <1425795335-6416-1-git-send-email-sfeldma@gmail.com> (raw)
From: Scott Feldman <sfeldma@gmail.com>
On ip route print dump, label externally offloaded routes with "external".
Offloaded routes are flagged with RTNH_F_EXTERNAL, a recent additon to
net-next. For example:
$ ip route
default via 192.168.0.2 dev eth0
11.0.0.0/30 dev swp1 proto kernel scope link src 11.0.0.2 external
11.0.0.4/30 via 11.0.0.1 dev swp1 proto zebra metric 20 external
11.0.0.8/30 dev swp2 proto kernel scope link src 11.0.0.10 external
11.0.0.12/30 via 11.0.0.9 dev swp2 proto zebra metric 20 external
12.0.0.2 proto zebra metric 30 external
nexthop via 11.0.0.1 dev swp1 weight 1
nexthop via 11.0.0.9 dev swp2 weight 1
12.0.0.3 via 11.0.0.1 dev swp1 proto zebra metric 20 external
12.0.0.4 via 11.0.0.9 dev swp2 proto zebra metric 20 external
192.168.0.0/24 dev eth0 proto kernel scope link src 192.168.0.15
