hello All,
I just installed Mitaka release with DVR and ml2+OVS,everything looks fine .
vms are getting ip address,floating IP address is working,vms can talk to
lbaas namespace
How ever:
Communication from qrouter-namespace to lbass and dhcp namespace are not
working,because of that floating ip assigned on lbaas is not working.I am
not sure whats is broken,we are using VLAN segmentation,Even tried using
GRE but that didnt make any difference.
i am new to DVR and in my juno environment without DVR, DHCP namespace can
talk to lbaas and router namespace.
on one of the compute node:
ip netns exec qrouter-602e4399-1949-4f7f-9351-0921064a111b ip l
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
20: qr-0d106417-3b: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc
noqueue state UNKNOWN mode DEFAULT group default
ovs-vsctl list-ifaces br-int
fg-70b8f7d1-1e
int-br-floating
int-br-prv
qr-0d106417-3b
qr-d1b616f7-45
qvo61d4d7d2-83
qvoc1f28f85-f6
ovs-vsctl show |grep -A 2 qr-0d106417-3b
Port "qr-0d106417-3b"
tag: 1
Interface "qr-0d106417-3b"
type: internal
Port "qvo61d4d7d2-83"
any idea why DVR is not able to talk to qdhcp and qlbaas ,but vms can talk
to both namespaces.
Regards,
Kevi
