ASA/PIX: Load balancing between two ISP-options
VERSION 7
Is it possible to load balance between two ISP links?
Does the ASA support PBR (Policy Based Routing )?
Does the ASA support secondary IP address on interfaces?
What other
default route forwarding rule. Cisco, Huawei, Huawei and other enterprise-class routers and three-layer switches generally support the function of PBR, but the specific operation may be different, the principle of datong small meaning.We implemented VLAN-based load balancing by using PBR, for example, there were 600 people in the company, one VLAN per 100 people
, etc., the equalization algorithm is also more flexible, such as random selection, Minimum number of connections and response time to distribute the load. NAT load Balancing can be implemented by means of hardware and software. A device that implements NAT load balancing b

HSRPcisco and VRRP are the most common gateway redundancy technologies. Similar to VRRP, HSRP is composed of multiple routers.
A vro is a virtual gateway, and a vro is active.
It is replaced by a device to implement transparent switching to users. However, we hope to achieve redundancy at the same time.

1. DNS load balancing method
The RR-DNS (round-robin Domain Name System) takes turns by: In a DNS server,You can configure the same name for multiple IP addresses. When the client queries this name, it will get an address when parsing this name. Therefore, for the same name, different clients will get differentTo achieve
Recently participated in A10 load balancing equipment training and wrote basic configuration notes based on personal understanding. Cisco ACE modules have been used before, and the fundamentals are consistent.
Note: If there is an understanding error please give the point, thank you.
