juniper SRX 利用虚拟路由器实现多链路冗余以及双向接入案例
Juniper 防火墙的多路由共享方案
Juniper 防火墙的多路由共享方案●问题的提出在企业网维护实践中，常常遇到用户外网接口故障，导致用户邮件等业务中断，严重影响用户工作。
解决此类问题的方法是多运营商网络接口。
当一个接口故障时其它接口能保证用户业务正常运行。
●解决方案1.如何在防火墙上配置使用这些接口，首先想到的是首选路由/二选路由方案。
当首选路由故障后，使用二选路由。
路由数据示例如下：ID IP-Prefix Interface Gateway P Pref Mtr Vsys* 8 0.0.0.0/0 ethernet3 1.1.1.250 C 0 1 Root9 0.0.0.0/0 ethernet2 2.2.2.250 S 20 1 Root该方案的缺陷是不能充放利用多个运用商提供的带宽，二选路由只能在首选路由故障后才能使用。
2.使用等价多径路由EQUAL COST MULTIPATH ROUTING，正常情况下两个路由均衡负荷外网流量，充分利用现有的带宽资源。
Juniper Netscreen ECMP配置注意点：✓ScreenOS 5.1版本以上支持✓两条路由需具有相同的优先级和Metric值，两条路由的出接口需在同一安全区段。
✓配置的两条同一目标路由在路由表中有效（*号）。
✓启用ECMP功能路由数据示例如下：ID IP-Prefix Interface Gateway P Pref Mtr Vsys * 8 0.0.0.0/0 ethernet3 1.1.1.250 C 0 1 Root * 9 0.0.0.0/0 ethernet2 2.2.2.250 S 0 1 Root具体实施如下✓打开EQUAL COST MULTIPATH ROUTING功能✓设置静态路由的preference值为0（与连接路由的preference值相同）✓设置静态路由，保证两个共享的路由有相同的metricset route 0.0.0.0/0 interface ethernet3 gateway 1.1.1.250 metric 1set route 0.0.0.0/0 interface ethernet4 gateway 2.2.2.250 metric 1。
单台JuniperSSG双ISP接入
单台JuniperSSG双ISP接入单Juniper SSG 双ISP接入冗余幸得公司有两条 ISP，有一台小墙Juniper SSG 5（两台SSG 550在生产环境中，不能拿来实验）拿来做个双ISP接入实验。
SSG 5的ScreenOS 为6.3.0r17。
在juniper上做DHCP服务器，给客户端分配IP，Untrust口IP 被遮盖。

juniper防火墙双机配置案例
概述juniper防火墙的双机具有高冗余性和安全性，便于管理，分为三种组网模式：layer3的A/P组网模式layer3的full-mesh的A/P组网模式layer3的full-mesh的A/A组网模式其中layer3A/P模式对环境要求最低，是业界广为流行的配置。
但是，其利用率不高，同一时间只有一台防火墙处理网络流量，一侧链路和设备出现故障时提供冗余切换。
配置要求硬件和软件版本相同，接口编号相同，放入HA的接口要统一。
配置时只需清空备的那一台，然后将HA、manger ip 、MGT端口ip，及个性化配置即可。
两台防火墙用e4口连接。
配置主防火墙unset interface e4 ip//清空e4口的ip地址set interface e4 zone ha//将e4口和HA区域绑定//-----配置NSRP----set nsrp cluster id 1//设置cluster组号set nsrp vsd id 0//设置虚拟安全数据库的组号0set nsrp vsd-group id 0 priority 50//设置nsrp主设备的优先级（优先级数值越大，优先级越小）set nsrp rto syn//设置配置同步set nsrp vsd-group id 0 monitor interface ethernet3set nsrp vsd-group id 0 monitor interface ethernet1//设置防火墙监控的端口//只有当备份防火墙配置之后，主设备上才能检测到备防火墙的状态（get nsrp）set nsrp vsd-group hb-interval 200//设置心跳信息每隔200秒发送问候信息set nsrp vsd-group hb-threshold 3//设置心跳信息总共发出3次问候信息save//保存配置备防火墙unset all//恢复出厂设置set interface e4 zone ha//将e4和ha区域绑定set nsrp cluster id 1//设置cluster组号set nsrp vsd id 0//设置vsd组号set nsrp vsd-group id 0 priority 100//设置nsrp主设备的优先级（优先级数值越大，优先级越小）set nsrp rto syn//设置配置同步set nsrp vsd-group id 0 monitor interface ethernet3set nsrp vsd-group id 0 monitor interface ethernet1//设置防火墙监控的端口set nsrp vsd-group hb-interval 200//设置心跳信息每隔200秒发送问候信息set nsrp vsd-group hb-threshold 3//设置心跳信息总共发出3次问候信息save //保存同步配置在备机上操作exec nsrp sync global-config check-sum//将两台设备的配置进行校检，如有不同，备份的设备将会在重启后把主设备上的配置导入备份主机中exec nsrp sync global-config save//如有不同，备份的设备将会在重启后把主设备上的配置导入备份主机中。
juniper 防火墙配置双线路负载
Juniper Netscreen 204防火墙Untrust接口倒换作者 马钢博客 版本 2009021101需求Netscreen 204防火墙拥有两个公网接口，当主接口链路失效时，如ISP故障，则将流量转移到备份接口。
解决方法图 1 网络拓扑如图 1所示，由主接口ethernet2检测ISP网关连通性，如果网关不可达，则标记主接口down，ethernet3自动作为默认出口。

Juniper SRX防火墙简明配置手册
Juniper SRX防火墙简明配置手册SRX系列防火墙是Juniper公司基于JUNOS操作系统的安全系列产品，JUNOS集成了路由、交换、安全性和一系列丰富的网络服务。
目前Juniper公司的全系列路由器产品、交换机产品和SRX安全产品均采用统一源代码的JUNOS操作系统，JUNOS是全球首款将转发与控制功能相隔离，并采用模块化软件架构的网络操作系统。
JUNOS作为电信级产品的精髓是Juniper 真正成功的基石，它让企业级产品同样具有电信级的不间断运营特性，更好的安全性和管理特性，JUNOS软件创新的分布式架构为高性能、高可用、高可扩展的网络奠定了基础。
基于NP架构的SRX系列产品产品同时提供性能优异的防火墙、NAT、IPSEC、IPS、SSL VPN和UTM 等全系列安全功能，其安全功能主要来源于已被广泛证明的ScreenOS操作系统。
本文旨在为熟悉Netscreen防火墙ScreenOS操作系统的工程师提供SRX防火墙参考配置，以便于大家能够快速部署和维护SRX防火墙，文档介绍JUNOS操作系统，并参考ScreenOS配置介绍SRX防火墙配置方法，最后对SRX防火墙常规操作与维护做简要说明。
一、JUNOS操作系统介绍1.1 层次化配置结构JUNOS采用基于FreeBSD内核的软件模块化操作系统，支持CLI命令行和WEBUI两种接口配置方式，本文主要对CLI命令行方式进行配置说明。
JUNOS CLI使用层次化配置结构，分为操作（operational）和配置（configure）两类模式，在操作模式下可对当前配置、设备运行状态、路由及会话表等状态进行查看及设备运维操作，并通过执行config或edit命令进入配置模式，在配置模式下可对各相关模块进行配置并能够执行操作模式下的所有命令（run）。
在配置模式下JUNOS采用分层分级模块下配置结构，如下图所示，edit命令进入下一级配置（类似unix cd命令）,exit命令退回上一级，top命令回到根级。

Juniper SRX防火墙双链路配置实例一
拓扑图：需求：PC1和PC2主机访问http服务走ge-0/0/0（wan1），访问telnet服务走ge-0/0/1（wan2）。
其余走ge-0/0/0（wan1）。
配置过程：第一步，创建路由实例(routing-instance)set routing-instances wan1 instance-type forwardingset routing-instances wan1 routing-options static route 0.0.0.0/0 next-hop 202.100.1.1set routing-instances wan2 instance-type forwardingset routing-instances wan2 routing-options static route 0.0.0.0/0 next-hop 202.100.2.1wan1：路由实例的名称forwarding：路由实例的类型PS：每一个路由实例可以理解为一个单独的路由转发表。
第二步：设置路由信息组（rib-groups）set routing-options rib-groups routing_table_group import-rib inet.0set routing-options rib-groups routing_table_group import-rib wan1.inet.0set routing-options rib-groups routing_table_group import-rib wan2.inet.0说明：routing_table_group：路由信息组名称wan1.inet.0：如果wan1的话，它的路由转发表的命名就是wan1.inet.0，是自动生成的。
PS:As the two ISPs are part of inet.0, the rib-group configuration is required to import the directly connected routes of the ISP into the routing-instance. (来自官方解释)意思就是需要将直连的路由输入到路由实例中。
