1 配置思路
(1) 确保主备设备的软硬件环境一致
# 在配置HA功能之前,请先保证主/备设备的硬件环境和软件环境的一致性。
(2) 配置Router A
# 配置接口GigabitEthernet1/0/7的IPv4地址为2.1.1.2/24。
# 配置接口GigabitEthernet1/0/8的IPv4地址为2.1.10.2/24。
# 配置OSPF路由协议,保证路由可达,具体步骤略。
(3) 配置Router B
# 配置接口GigabitEthernet1/0/7的IPv4地址为10.1.1.2/24。
# 配置接口GigabitEthernet1/0/8的IPv4地址为10.1.10.2/24。
# 配置OSPF路由协议,保证路由可达,具体步骤略。
(4) 配置Device A
a. 配置接口IPv4地址
# 根据组网图中规划的信息,配置各接口的IPv4地址,具体配置步骤如下。
<DeviceA> system-view
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] ip address 2.1.1.1 255.255.255.0
[DeviceA-GigabitEthernet1/0/1] quit
请参考以上步骤配置其他接口的IP地址,具体配置步骤略。
b. 配置OSPF,保证路由可达
# 配置设备上的OSPF功能,OSPF协议自身的链路开销值建议保持默认配置即可。
[DeviceA] router id 2.1.1.1
[DeviceA] ospf
[DeviceA-ospf-1] area 0
[DeviceA-ospf-1-area-0.0.0.0] network 2.1.1.0 0.0.0.255
[DeviceA-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[DeviceA-ospf-1-area-0.0.0.0] quit
[DeviceA-ospf-1] quit
c. 配置高可靠性
# 配置Track项监控接口状态。
[DeviceA] track 1 interface gigabitethernet 1/0/1
[DeviceA-track-1] quit
[DeviceA] track 2 interface gigabitethernet 1/0/2
[DeviceA-track-2] quit
# 使用两台Device进行HA组网,Device A作为主设备,Device B作为备设备。当Device A或其链路发生故障时,由Device B接替Device A继续工作,保证业务不中断。
[DeviceA] remote-backup group
[DeviceA-remote-backup-group] remote-ip 10.2.1.2
[DeviceA-remote-backup-group] local-ip 10.2.1.1
[DeviceA-remote-backup-group] data-channel interface gigabitethernet 1/0/3
[DeviceA-remote-backup-group] device-role primary
RBM_P[DeviceA-remote-backup-group] undo backup-mode
RBM_P[DeviceA-remote-backup-group] hot-backup enable
RBM_P[DeviceA-remote-backup-group] configuration auto-sync enable
RBM_P[DeviceA-remote-backup-group] configuration sync-check interval 12
# 开启HA调整备设备上动态路由协议OSPF的开销值功能,并以绝对方式对外通告开销值,绝对值为6000。
RBM_P[DeviceA-remote-backup-group] adjust-cost ospf enable absolute 6000
# 配置HA与序号为1和2的Track项联动。
RBM_P[DeviceA-remote-backup-group] track 1
RBM_P[DeviceA-remote-backup-group] track 2
RBM_P[DeviceA-remote-backup-group] quit
d. 配置安全业务
# 以上有关HA的配置部署完成后,可以配置各种安全业务。对于HA支持配置信息备份的功能模块仅需要在此主管理设备上(Device A)进行配置即可。
(5) 配置Device B
a. 配置接口IPv4地址
# 根据组网图中规划的信息,配置各接口的IPv4地址,具体配置步骤如下。
<DeviceB> system-view
[DeviceB] interface gigabitethernet 1/0/1
[DeviceB-GigabitEthernet1/0/1] ip address 2.1.10.1 255.255.255.0
[DeviceB-GigabitEthernet1/0/1] quit
请参考以上步骤配置其他接口的IP地址,具体配置步骤略。
b. 配置OSPF,保证路由可达
# 配置设备上的OSPF功能,OSPF协议自身的链路开销值建议保持默认配置即可。
[DeviceB] router id 2.1.10.1
[DeviceB] ospf
[DeviceB-ospf-1] area 0
[DeviceB-ospf-1-area-0.0.0.0] network 2.1.10.0 0.0.0.255
[DeviceB-ospf-1-area-0.0.0.0] network 10.1.10.0 0.0.0.255
[DeviceB-ospf-1-area-0.0.0.0] quit
[DeviceB-ospf-1] quit
c. 配置高可靠性
# 配置Track项监控接口状态。
[DeviceB] track 1 interface gigabitethernet 1/0/1
[DeviceB-track-1] quit
[DeviceB] track 2 interface gigabitethernet 1/0/2
[DeviceB-track-2] quit
# 使用两台Device进行HA组网,Device A作为主设备,Device B作为备设备。当Device A或其链路发生故障时,由Device B接替Device A继续工作,保证业务不中断。
[DeviceB] remote-backup group
