msr 56-60三条宽带只有一条能用。

是默认接3条只会生效1条么？如果想3条一起用应该怎么做？

您好，可以三个同时用的呀，有可能现场的路由来回路径不一致导致的。

下面是配置，这个问题应该是哪里

您好，看到了默认路由这里有三条优先级一样的ip route-static 0.0.0.0 0 Dialer1 ip route-static 0.0.0.0 0 Dialer2 ip route-static 0.0.0.0 0 Dialer3 尝试给2和3的加个优先级100,120看下是否可以。

这种是做主备的形式么？

您好，在路由上是主备。可以使用策略路由让相应的业务走相应的出口。
