4.4 验证配置
通过display ip policy-based-route命令可以查看到当前策略路由配置已经配置成功:
[Device] display ip policy-based-route policy pbr1 Policy name: pbr1 node 0 permit: if-match acl 3005 apply next-hop 10.5.1.2 node 1 permit: if-match acl 3006 apply next-hop 10.3.1.2
# 通过tracert命令查看以下报文的转发路径(使用Tracert功能需要在中间设备上开启ICMP超时报文发送功能,在目的端开启ICMP目的不可达报文发送功能):
