Router External Gateway DOWN
Hi All,
I have checked the other questions: 219937 212848 216209
I have 'similar' issues, the main one would be:
ovs-ofctl show br-ex OFPT_FEATURES_REPLY (xid=0x1): ver:0x1, dpid:00000017a4774836 n_tables:255, n_buffers:256 features: capabilities:0xc7, actions:0xfff 1(eth1): addr:00:17:a4:77:48:36 config: 0 state: 0 current: FIBER AUTO_NEG advertised: 1GB-FD 10GB-FD FIBER AUTO_NEG AUTO_PAUSE AUTO_PAUSE_ASYM supported: 1GB-FD 10GB-FD FIBER AUTO_NEG AUTO_PAUSE AUTO_PAUSE_ASYM 2(qg-331c3226-a4): addr:f7:be:ff:7f:00:00 config: PORT_DOWN state: LINK_DOWN 3(phy-br-ex): addr:d6:ce:c6:5a:ad:4e config: 0 state: 0 current: 10GB-FD COPPER 4(tap664558c8-d4): addr:5e:c3:fb:85:e6:8d config: 0 state: 0 current: 10GB-FD COPPER LOCAL(br-ex): addr:00:17:a4:77:48:36 config: 0 state: 0 OFPT_GET_CONFIG_REPLY (xid=0x3): frags=normal miss_send_len=0
ovs-dpctl show br-ex system@br-ex: lookups: hit:11281 missed:3237 lost:2 flows: 10 port 0: br-ex (internal) port 1: eth1 Jul 18 16:58:12|00001|netdev_linux|WARN|/sys/class/net/qg-331c3226-a4/carrier: open failed: No such file or directory port 2: qg-331c3226-a4 (internal) port 3: phy-br-ex port 4: tap664558c8-d4
However that is where it stops, please see the rest of my symptoms and hopefully find where I have configured it incorrectly...
I'm using Quantum with VLANs, the external interface (eth1) is running in promiscuous mode with no IP set, if I trash the router and add a port from the shared 'public' network, the interface comes up and I can ping the gateway (or other hosts on that network).
Whereas if I set this network as a gateway of the router, the correct IPs are assigned however the router interface stays down and I cannot send icmp/packets.
I've set debugging and can't find anything obvious, I'm not sure where else to look, my config looks like this:
auto eth1 iface eth1 inet manual up ifconfig $IFACE 0.0.0.0 up up ifconfig $IFACE promisc down ifconfig $IFACE down
