juniper srx100B双机热备HA心得

配置SRX100 b双机热备HA心得：厂商指定F0/0/7-控制接口，F0/0/6-设备管理接口
1、配置 Cluster id 和 Node id
set chassis cluster cluster-id 1 node 0 reboot
set chassis cluster cluster-id 1 node 1 reboot
注：node越小，级别越高，为主设备。另外，需要先把接口删除，否则重启后不能进入configure模式。

2、配置控制接口和数据接口，数据这里接口我这里自己指定为F0/0/2
控制接口系统默认指定F0/0/7，不需要配置，直接2台设备F0/0/7互联就行。
set interfaces fab0 fabric-options member-interfaces fe-0/0/2
set interfaces fab1 fabric-options member-interfaces fe-1/0/2
注：数据接口不用配置ip

3、每个机箱的个性化配置 ：
set groups node0 system host-name SRX-A
set groups node0 interfaces fxp0 unit 0 family inet address 192.168.100.100/24 #####主设备的管理ip
set groups node1 system host-name SRX-B
set groups node1 interfaces fxp0 unit 0 family inet address 192.168.100.101/24#####备设备的管理ip
set apply-groups "${node}"
注：2台设备的管理ip都是fxp0，另外配置完成记得set apply-groups "${node}"，否则出现问题。

4、配置 Redundancy Group ：RG0为引擎切换。RG1为数据层面切换，记得此处有开启preemt抢占。
set chassis cluster reth-count 8
set chassis cluster redundancy-group 0 node 0 priority 200
set chassis cluster redundancy-group 0 node 1 priority 100
set chassis cluster redundancy-group 1 node 0 priority 200
set chassis cluster redundancy-group 1 node 1 priority 100
set chassis cluster redundancy-group 1 preempt
set chassis cluster redundancy-group 1 interface-monitor fe-0/0/0 weight 255########配置接口interface-monitor
set chassis cluster redundancy-group 1 interface-monitor fe-0/0/1 weight 255########配置接口interface-monitor
set chassis cluster redundancy-group 1 interface-monitor fe-1/0/0 weight 255########配置接口interface-monitor
set chassis cluster redundancy-group 1 interface-monitor fe-1/0/1 weight 255########配置接口interface-monitor

5、将interface-monitor加入到冗余接口reth0 reth2，并把冗余接口加入到RG1
set interfaces fe-0/0/0 fastether-options redundant-parent reth0
set interfaces fe-0/0/0 unit 0
set interfaces fe-0/0/1 fastether-options redundant-parent reth2
set interfaces fe-0/0/1 unit 0
set interfaces fe-1/0/0 fastether-options redundant-parent reth0
set interfaces fe-1/0/0 unit 0
set interfaces fe-1/0/1 fastether-options redundant-parent reth2
set interfaces fe-1/0/1 unit 0
set interfaces reth0 redundant-ether-options redundancy-group 1
set interfaces reth2 redundant-ether-options redundancy-group 1

6、给冗余接口reth0 reth2配置ip，划入对应的区域，及策略放通。
set interfaces reth0 unit 0 family inet address 202.100.1.10/24
set interfaces reth2 unit 0 family inet address 192.168.10.10/24
set security zones security-zone untrust interfaces reth0.0 host-inbound-traffic system-services all
set security zones security-zone untrust interfaces reth0.0 host-inbound-traffic protocols all
set security zones security-zone trust interfaces reth2.0 host-inbound-traffic system-services all
set security zones security-zone trust interfaces reth2.0 host-inbound-traffic protocols all

set security policies from-zone untrust to-zone trust policy untrust-to-trust match source-address any
set security policies from-zone untrust to-zone trust policy untrust-to-trust match destination-address any
set security policies from-zone untrust to-zone trust policy untrust-to-trust match application any
set security policies from-zone untrust to-zone trust policy untrust-to-trust then permit
set security policies from-zone trust to-zone trust policy trust-to-trust match source-address any
set security policies from-zone trust to-zone trust policy trust-to-trust match destination-address any
set security policies from-zone trust to-zone trust policy trust-to-trust match application any
set security policies from-zone trust to-zone trust policy trust-to-trust then permit
