Dear All,
I met with some issue when using simple gateway:
It's reproducible:
1. in the testbed, 3 controller and 2 simple gateways. the 2 simple gateways
are also used as compute nodes.
the 2 simple gateway are connnect with IP fabric: 172.16.159.x/24
2. configure public network.(172.16.159.x/24)
3. create a vm, which directly connnect with the public network. it's ip
address: 172.16.159.4
4. we can successfully ping hosts in IP fabric, 172.16.26.134.
5. when ping from host(172.16.26.134) in IP fabric to the vm(172.16.159.4), it
doesn't work.
some further debug info:
the ping request packet has been sent to vrouter from the vgw interface. and
then send to vrouter-agent via pkt0.
and in vrouter-agent, in function: PktFlowInfo::Process():
if (in->intf_ == NULL ||
(pkt->l3_forwarding == true &&
in->intf_->ip_active(pkt->family) == false) ||
(pkt->l3_forwarding == false &&#####@@@@@@@@@@@the function returns
with false, because "pkt->l3_forwarding == false&& in->intf_->l2_active() ==
false"
in->intf_->l2_active() == false)) {
in->intf_ = NULL;
LogError(pkt, "Invalid or Inactive ifindex");
short_flow = true;
short_flow_reason = FlowEntry::SHORT_UNAVIALABLE_INTERFACE;
return false;
}
here is the output of command flow -l:
Index Source:Port Destination:Port Proto(V)

Thanks for your help!
