使用linux 命名空间ip netns和OVS连接两个不通网段的机器不通？

Question

一、网络拓扑
主机1（192.168.100.11）---->路由主机ens34口----->绑定至OVS网桥
主机2（192.168.200.22）---->路由主机ens35口----->绑定至OVS网桥
虚接口vport1(192.168.100.254)------>绑定至OVS网桥接口vport1_br
虚接口vport2(192.168.200.254)------>绑定至OVS网桥接口vport2_br
虚接口vport1,2均在命名空间ns-router中

                   ns-router(路由作用)  
                    |    |
client1---ens34---OVS-bridge----ens35---client2

二、配置

ovs-vsctl show
55423833-9ef8-4908-8262-c293a0ab892e
    Bridge "l2-lyz-br"
        Port "vport1_br"
            Interface "vport1_br"
        Port "l2-lyz-br"
            Interface "l2-lyz-br"
                type: internal
        Port "ens35"
            Interface "ens35"
        Port "ens34"
            Interface "ens34"
        Port "vport2_br"
            Interface "vport2_br"
    ovs_version: "2.11.1"

 ip netns exec ns-router ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
12: vport1@if11: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether ca:d8:63:0e:8c:e2 brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet 192.168.100.254/24 scope global vport1
       valid_lft forever preferred_lft forever
    inet6 fe80::c8d8:63ff:fe0e:8ce2/64 scope link
       valid_lft forever preferred_lft forever
14: vport2@if13: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether ca:27:1e:fd:c0:c4 brd ff:ff:ff:ff:ff:ff link-netnsid 0

       valid_lft forever preferred_lft forever
    inet6 fe80::c827:1eff:fefd:c0c4/64 scope link
       valid_lft forever preferred_lft forever

linux CentOS7 1804开启ip转发功能：echo "1" > /proc/sys/net/ipv4/ip_forward

问题为：
1.在主机1上Ping192.168.200.22不通
2.在ns-router中抓包看到vport1可以收到数据包但是并未转发
3.client1可以ping通192.168.100.254和200.254

求大神帮忙看下这样是否行得通或者哪里缺少配置，感激不尽！

问题解决了 忘记了在命名空间中开启net.ipv4.ip_forward=1
