防火墙负载口字形连接,能不能两端都起ha vrrp来对接?可以的话请分享下配置和注意事项,感谢。

先配置VRRP,然后再配置链路负载
用户从两个运营商ISP 1和ISP 2处分别租用了链路Link 1和Link 2,这两条链路的路由器跳数、带宽和成本均相同,但Link 1的网络延迟小于Link 2。通过配置链路负载均衡,使Host访问Server时优先选择这两条链路中的最优链路。
图3-4 出方向链路负载均衡基本组网配置组网图
(1) 配置接口IP地址
# 根据组网图中规划的信息,配置各接口的IP地址,具体配置步骤如下。
<Device> system-view
[Device] interface gigabitethernet 1/0/1
[Device-GigabitEthernet1/0/1] ip address 10.1.1.1 255.255.255.0
[Device-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。
(2) 配置接口加入安全域。
# 请根据组网图中规划的信息,将接口加入对应的安全域,具体配置步骤如下。
[Device] security-zone name untrust
[Device-security-zone-Untrust] import interface gigabitethernet 1/0/1
[Device-security-zone-Untrust] import interface gigabitethernet 1/0/2
[Device-security-zone-Untrust] quit
[Device] security-zone name trust
[Device-security-zone-Trust] import interface gigabitethernet 1/0/3
[Device-security-zone-Trust] quit
(3) 配置安全策略
配置安全策略放行Trust与Untrust安全域、Local与Untrust安全域之间的流量,用于用户访问外网服务器。
# 配置名称为lbrule1的安全策略规则,使用户可以访问外网服务器,具体配置步骤如下。
[Device] security-policy ip
[Device-security-policy-ip] rule name lbrule1
[Device-security-policy-ip-1-lbrule1] source-zone trust
[Device-security-policy-ip-1-lbrule1] destination-zone untrust
[Device-security-policy-ip-1-lbrule1] source-ip-subnet 192.168.1.0 255.255.255.0
[Device-security-policy-ip-1-lbrule1] action pass
[Device-security-policy-ip-1-lbrule1] quit
# 配置名称为lblocalout的安全策略规则,使Device可以向链路下一跳发送健康检测报文,具体配置步骤如下。
[Device-security-policy-ip] rule name lblocalout
[Device-security-policy-ip-2-lblocalout] source-zone local
[Device-security-policy-ip-2-lblocalout] destination-zone untrust
[Device-security-policy-ip-2-lblocalout] destination-ip-subnet 10.1.1.0 255.255.255.0
[Device-security-policy-ip-2-lblocalout] destination-ip-subnet 20.1.1.0 255.255.255.0
[Device-security-policy-ip-2-lblocalout] action pass
[Device-security-policy-ip-2-lblocalout] quit
[Device-security-policy-ip] quit
(4) 配置链路组
# 创建ICMP类型的NQA模板t1,并配置每次探测结果发送机制。
[Device] nqa template icmp t1
[Device-nqatplt-icmp-t1] reaction trigger per-probe
[Device-nqatplt-icmp-t1] quit
# 指定缺省就近性探测方法为t1,并配置就近性计算的网络延迟权值为200。
[Device] loadbalance proximity
[Device-lb-proximity] match default probe t1
[Device-lb-proximity] rtt weight 200
[Device-lb-proximity] quit
# 创建链路组lg,开启就近性功能,关闭NAT功能。
[Device] loadbalance link-group lg
[Device-lb-lgroup-lg] proximity enable
[Device-lb-lgroup-lg] transparent enable
[Device-lb-lgroup-lg] quit
(5) 配置链路
# 创建链路link1和link2,配置link1的下一跳IPv4地址为10.1.1.2,link2的下一跳IPv4地址为20.1.1.2,并加入链路组lg。
[Device] loadbalance link link1
[Device-lb-link-link1] router ip 10.1.1.2
[Device-lb-link-link1] link-group lg
[Device-lb-link-link1] quit
[Device] loadbalance link link2
[Device-lb-link-link2] router ip 20.1.1.2
[Device-lb-link-link2] link-group lg
[Device-lb-link-link2] quit
(6) 配置虚服务器
# 创建LINK-IP类型的虚服务器vs,配置其VSIP为通配0.0.0.0/0,指定其缺省主用链路组为lg,并开启此虚服务器。
[Device] virtual-server vs type link-ip
[Device-vs-link-ip-vs] virtual ip address 0.0.0.0 0
[Device-vs-link-ip-vs] default link-group lg
[Device-vs-link-ip-vs] service enable
[Device-vs-link-ip-vs] quit
# 显示所有链路的简要信息。
[Device] display loadbalance link brief
Link Route IP State VPN instance Link group
link1 10.1.1.2 Active lg
link2 20.1.1.2 Active lg
# 显示所有链路组的详细信息。
