TC QDISC在OpenWrt中使用GRE

Question

我正在尝试在OpenWrt板上实现流量控制到GRE接口。为此，我遵循以下步骤

Create GRE interface named gre1 in both tunnel end devices.
Tested reachability with ping, Success.
create qdisc using following command.
tc qdisc add dev gre1 root handle 1: default 2
Before creating tc classes i tired to ping the tunnel interface but this failed. 
I tried to capture packet in gre1 but found 0 packets.
Monitored the statistics of qdisc using the command
tc -p -s -d qdisc show dev gre1
found that packet drop count is increasing.

我已经在Ubuntu PC上测试过，并发现工作。另外，如果我将隧道更改为VPN隧道而不是GRE，则可以正常工作。

我还有其他需要处理的事情以在GRE中实现TC？

任何帮助将不胜感激。

固定！

添加类

tc类添加dev eth0 parent 1：1 classid 1：2 htb速率60kbps ceil 100kbps

然后为类添加SFQ

tc qdisc add dev eth0 parent 1:2 handle 20: sfq
