Unknown Router Interface in DVR Mode
Hi everyone,
After I enabled the DVR, my tenant router gets an extra interface in addition to the tenant network gateway. That extra interface only shows up in the Horizon dashboard, not in the command line output. Does anyone know what that interface is for?
Here are some details to help explain what I encountered:
On the compute node:
[root@compute ~]# ip netns
fip-eadd51b1-1b0a-4504-b694-4f54b7b60d3d (id: 1)
qrouter-b7570af0-42f6-499d-bbf0-2139a98bc0a3 (id: 0)
[root@compute ~]# ip netns exec qrouter-b7570af0-42f6-499d-bbf0-2139a98bc0a3 ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo

link/ether ca:08:94:69:b9:6c brd ff:ff:ff:ff:ff:ff link-netnsid 0
inet 169.254.106.114/31 scope global rfp-b7570af0-4
valid_lft forever preferred_lft forever
inet6 fe80::c808:94ff:fe69:b96c/64 scope link
valid_lft forever preferred_lft forever
13: qr-bd3e180e-2d: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN group default qlen 1000
link/ether fa:16:3e:c4:a8:3c brd ff:ff:ff:ff:ff:ff
inet 192.168.0.1/24 brd 192.168.0.255 scope global qr-bd3e180e-2d
valid_lft forever preferred_lft forever
inet6 fe80::f816:3eff:fec4:a83c/64 scope link
valid_lft forever preferred_lft forever
In above, the router has only one qr interface (qr-bd3e180e-2d) at IP 192.168.0.1/24 which is the tenant network gateway, as expected.
From the Horizon dashboard:
Name Fixed IPs
(bd3e180e-2dd6) 192.168.0.1
(da7884d9-2ff1) 192.168.0.5
Notice there is an extra, unknown interface (da7884d9-2ff1) at 192.168.0.5. Could someone explain to me what that interface is for?
Thank you very much!
