Hi guys:
I just try to create two GRE tunnels between two hosts, the result
is I can't do this.
vswitch complains "could not create iface test: File exists" when
creating second tunnel.
I did set different GRE keys for tunnels.
I google and get some articles said it's possible to create
multiple GRE tunnels with same src/dst.
I am curious what technical barrier prevents our doing since GRE
key is an natural tag to distinguish different tunnels.
BTW: when the interface created failed, ovs-vsctl also returns a
uuid as if it succeeds. This is very puzzle, the real result in log is:
"
Dec 30 14:40:06|04201|bridge|INFO|created port test on bridge test
Dec 30 14:40:06|04202|bridge|WARN|could not create iface test: File exists
Dec 30 14:40:06|04203|bridge|WARN|bridge test: port test has no
interfaces, dropping
"
cloud we have more graceful way to report such failure?
thank you.
