我需要使用 fastethernet 接口连接两个 Juniper 路由器。当我通过em0连接时，我可以通过ping检查它们之间的连接。但是当我尝试在两个路由器中设置 fe-0/0/0 时，我无法 ping 通它们。我看到这条消息：ping: sendto: No route to host。如何解决这个问题？
我的第一个路由器配置是这样的：
fe-1/0/0 {
unit 0 {
family inet {
address 192.168.1.2/24;
}
}
em1 {
description R1;
vlan-tagging;
unit 0 {
vlan-id 10;
family inet {
address 192.168.10.1/30;
}
}
第二个是这样的：
fe-1/0/0 {
unit 0 {
family inet {
address 192.168.1.1/24;
}
}
em1 {
description R2;
vlan-tagging;
unit 0 {
vlan-id 10;
family inet {
address 192.168.10.2/30;
}
}
症状：
