Hi guys:
I have openstack Liberty(linuxbridge + vxlan) installed, and the vm could not
get IP from dhcp server.
Troubleshooting:
Using tcpdump can get dhcp discover packet on physical NIC on network node, but
can't get it on vxlan port(vxlan-100) on network node.
In opposite direction, Sending arp broadcast in dhcp namespace, and we can get
packet on vxlan port(vxlan-100) but can't get packet on physical NIC.
However, we find port 8472 is being listened. Meanwhile all
interfaces(vxlan-100, physical NIC) are up and running.
What could be the reason for the issue? Any comments are appreciated.
BR,
Jingting
