为机箱 1 配置接口。
逐步过程
每个 HA 对路由器的接口配置相同，以下服务 PIC 选项除外：
redundancy-options redundancy-peer ipaddress addressunit unit-number family inet address address为 0 以外的单元，其中包含选项ip-address-owner service-plane
要配置接口：
在机箱 1 上配置冗余服务 PIC。
[edit interfaces} user@host# set interfaces vms-4/0/0 redundancy-options redundancy-peer ipaddress 5.5.5.2 user@host# set interfaces vms-4/0/0 redundancy-options routing-instance HA user@host# set interfaces vms-4/0/0 unit 10 ip-address-owner service-plane user@host# set interfaces vms-4/0/0 unit 10 family inet address 5.5.5.1/32 user@host# set interfaces vms-4/0/0 unit 20 family inet user@host# set interfaces vms-4/0/0 unit 20 service-domain inside user@host# set interfaces vms-4/0/0 unit 30 family inet user@host# set interfaces vms-4/0/0 unit 30 service-domain outside
为机箱 1 配置用作机箱间链路的接口，以实现同步流量。
user@host# set interfaces ge-2/0/0 vlan-tagging user@host# set interfaces ge-2/0/0 unit 0 vlan-id 100 family inet address 20.1.1.1/24
根据需要配置剩余接口。
结果
user@host# show interfaces
ge-2/0/0 {
vlan-tagging;
unit 0 {
vlan-id 100;
family inet {
address 20.1.1.1/24;
}
}
}

}
unit 20 {
family inet;
family inet6;

}
unit 30 {
family inet;
family inet6;
service-domain outside;
}
}
}
配置机箱 1 的路由信息
逐步过程
此示例不包括详细的路由配置。机箱之间的 HA 同步流量需要使用路由实例，如下所示：
为机箱 1 配置路由实例。
user@host# set routing-instances HA instance-type vrf user@host# set routing-instances HA interface ge-2/0/0.0 user@host# set routing-instances HA interface vms-4/0/0.10 user@host# set routing-instances HA route-distinguisher 1:1 user@host# set policy-options policy-statement dummy term 1 then reject user@host# set routing-instances HA vrf-import dummy user@host# set routing-instances HA vrf-export dummy user@host# set routing-instances HA routing-options static route route 5.5.5.1/32 next-hop vms-4/0/0.10 user@host# set routing-instances HA routing-options static route route 5.5.5.2/32 next-hop 20.1.1.2
结果
user@host# show routing-instances
HA {
instance-type vrf;
interface ge-2/0/0.0;
interface vms-4/0/0.10;
route-distinguisher 1:1;
vrf-import dummy;
vrf-export dummy;
routing-options {
static {
route 5.5.5.1/32 next-hop vms-4/0/0.10;
route 5.5.5.2/32 next-hop 20.1.1.2;
}
}
}
为机箱配置 NAT 和有状态防火墙 1
逐步过程
在两个路由器上相同配置 NAT 和有状态防火墙。要配置 NAT 和有状态防火墙：
根据需要配置 NAT。
user@host# set services nat pool p2 address 32.0.0.0/24 user@host# set services nat pool p2 port automatic random-allocation user@host# set services nat pool p2 address-allocation round-robin user@host# set services nat rule r2 match-direction input user@host# set services nat rule r2 term t1 from source-address 129.0.0.0/8 user@host# set services nat rule r2 term t1 from source-address 128.0.0.0/8 user@host# set services nat rule r2 term t1 then translated source-pool p2 user@host# set services nat rule r2 term t1 then translated translation-type napt-44 user@host# set services nat rule r2 term t1 then translated address-pooling paired user@host# set services nat rule r2 term t1 then syslog
根据需要配置有状态的防火墙。
user@host# set services stateful-firewall rule r2 match-direction input user@host# set services stateful-firewall rule r2 term t1 from source-address any-unicast user@host# set services stateful-firewall rule r2 term t1 then accept user@host# set services stateful-firewall rule r2 term t1 then syslog
结果
user@host# show services nat
nat {
pool p2 {
address 32.0.0.0/24;
port {
automatic {
random-allocation;
}
}
address-allocation round-robin;
}
rule r2 {
match-direction input;
term t1 {
from {
source-address {
129.0.0.0/8;
128.0.0.0/8;
}
}
then {
translated {
source-pool p2;
translation-type {
napt-44;
}
address-pooling paired;
}
syslog;
}
}
}
}
}
user@host show services stateful-firewell
rule r2 {
match-direction input;
term t1 {
from {
source-address {
any-unicast;
}
}
then {
accept;
syslog;
}
}
}
配置服务集
逐步过程
在两个路由器上完全相同地配置服务集。要配置服务集：
配置服务集复制选项。
user@host# set services service-set ss2 replicate-services replication-threshold 180 user@host# set services service-set ss2 replicate-services stateful-firewall user@host# set services service-set ss2 replicate-services nat
为服务集配置对 NAT 和有状态防火墙规则的引用。
user@host# set services service-set ss2 stateful-firewall-rules r2 user@host# set services service-set ss2 nat-rules r2
在 vms-PIC 上配置下一跃点服务接口。
user@host# set services service-set ss2 next-hop-service inside-service-interface vms-4/0/0.20 user@host# set services service-set ss2 next-hop-service outside-service-interface vms-4/0/0.30
配置所需的日志记录选项。
user@host# set services service-set ss2 syslog host local class session-logs user@host# set services service-set ss2 syslog host local class stateful-firewall-logs user@host# set services service-set ss2 syslog host local class nat-logs
结果
user@host# show services service-set ss2
syslog {
host local {
class {
session-logs;
inactive: stateful-firewall-logs;
nat-logs;
}
}
}
replicate-services {
replication-threshold 180;
stateful-firewall;
nat;
}
stateful-firewall-rules r2;
inactive: nat-rules r2;
next-hop-service {
inside-service-interface vms-3/0/0.20;
outside-service-interface vms-3/0/0.30;
}
}
为机箱 2 配置接口
逐步过程
每个 HA 对路由器的接口配置相同，以下服务 PIC 选项除外：
redundancy-options redundancy-peer ipaddress addressunit unit-number family inet address address为 0 以外的单元，其中包含选项ip-address-owner service-plane
在机箱 2 上配置冗余服务 PIC。
指向
redundancy-peer ipaddress机箱 1 上 vms-4/0/0 上包含语句的单元（单元 10ip-address-owner service-plane）的地址。[edit interfaces} set interfaces vms-4/0/0 redundancy-options redundancy-peer ipaddress 5.5.5.1 user@host# set interfaces vms-4/0/0 redundancy-options routing-instance HA user@host# set interfaces vms-4/0/0 unit 10 ip-address-owner service-plane user@host# set interfaces vms-4/0/0 unit 10 family inet address 5.5.5.2/32 user@host# set interfaces vms-4/0/0 unit 20 family inet user@host# set interfaces vms-4/0/0 unit 20 service-domain inside user@host# set interfaces vms-4/0/0 unit 30 family inet user@host# set interfaces vms-4/0/0 unit 30 service-domain outside
为机箱 2 配置用作机箱间链路的接口，以实现同步流量
user@host# set interfaces ge-2/0/0 vlan-tagging user@host# set interfaces ge-2/0/0 unit 0 vlan-id 100 family inet address 20.1.1.2/24
根据需要为机箱 2 配置剩余接口。
结果
user@host# show interfaces
vms-4/0/0 {
redundancy-options {
redundancy-peer {
ipaddress 5.5.5.1;
}
routing-instance HA;
}
unit 0 {
family inet;
}
unit 10 {
ip-address-owner service-plane;
family inet {
address 5.5.5.2/32;
}
}
ge-2/0/0 {
vlan-tagging;
unit 0 {
vlan-id 100;
family inet {
address 20.1.1.2/24;
}
}
unit 10 {
vlan-id 10;
family inet {
address 2.10.1.2/24;
}
配置机箱 2 的路由信息
逐步过程
此示例不包括详细的路由配置。两个机箱之间的 HA 同步流量需要路由实例，此处包含。
为机箱 2 配置路由实例。
user@host# set routing-instances HA instance-type vrf user@host# set routing-instances HA interface ge-2/0/0.0 user@host# set routing-instances HA interface vms-4/0/0.10 user@host# set routing-instances HA route-distinguisher 1:1 user@host# set policy-options policy-statement dummy term 1 then reject user@host# set routing-instances HA vrf-import dummy user@host# set routing-instances HA vrf-export dummy user@host# set routing-instances HA routing-options static route 5.5.5.2/32 next-hop vms-4/0/0.10 user@host# set routing-instances HA routing-options static route 5.5.5.1/32 next-hop 20.1.1.1
注意：以下配置步骤与为机箱 1 显示的步骤 相同 。
配置 NAT 和有状态防火墙
配置服务集
结果
user@host# show services routing-instances
HA {
instance-type vrf;
interface xe-2/2/0.0;
interface vms-4/0/0.10;
