在linux服務器(centos7.x) 上 創建3個網橋
配置如下

br0 沒有關聯vlan
br2和br3 分別關聯vlan2 和vlan3
br2上有個虛擬機 發組播資料包 組播地址為239.0.0.2 ，請問需要添加什么路由或者什么設定 才能將組播資料包怎么轉到非vlan的 br0 和 具有vlan的 br3上
我已經做的嘗試如下 都沒有效果（用 tcpdump -i br3 都沒有組播資料包）：
1.打開IP轉發：
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.也安裝了pimd 啟動了（但是默認配置 不知道怎么配置）
內核組播路由開關也已經打開
cat /proc/sys/net/ipv4/conf/all/mc_forwarding
