SR同时发布路由，因此对于用户下行流量，会同时下发到主备用 SR，流量到达备用的 SR后，通过 redundant-interface 送回到主用 SR，如下图所示：RadiusSR/BRAS1信信信信信信信信 BRAS信信SR2信信信信信信LACPSRRPLACP信信信SWETH-TRUNKLACPOLTONU信信1信信2这样会导致备用侧的上下行重复流量， 无形中导致可用带宽变小，因此，必须抑制备用侧发布路由，由于 7750 启用 SRRP后，会产生 srrp-master 和 srrp-non-master 两种类型的路由， 备用侧只要抑制 srrp-non-master 类型的路由就可以了。设备配置GDGZ-MS-IPMAN-XY-BRAS01-7750下行链路起 LACPconfigrue lag 4description
