组播在vlan之间路由问题

[dns007]

在linux服务器(centos7.x) 上 创建3个网桥
配置如下
[root@TAE_Node1 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo

2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 state UP qlen 1000

3: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue master br0 state UP qlen 1000

5: bond0.2@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master br2 state UP qlen 1000

6: br2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000

7: bond0.3@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master br3 state UP qlen 1000

8: br3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000

valid_lft forever preferred_lft forever

br0 没有关联vlan
br2和br3 分别关联vlan2 和vlan3

br2上有个虚拟机 发组播数据包 组播地址为239.0.0.2 ，请问需要添加什么路由或者什么设置 才能将组播数据包怎么转到非vlan的 br0 和 具有vlan的 br3上

我已经做的尝试如下 都没有效果（用 tcpdump -i br3 都没有组播数据包）：
1.打开IP转发：
echo 1 > /proc/sys/net/ipv4/ip_forward

2.添加路由：
route add -net 239.0.0.2 netmask 255.255.255.255 dev br3
route add -net 239.0.0.2 netmask 255.255.255.255 dev br0

3.也安装了pimd 启动了（但是默认配置 不知道怎么配置）
内核组播路由开关也已经打开
cat /proc/sys/net/ipv4/conf/all/mc_forwarding
