Our company safety equipment is often in the export of network, and now the network which acts as the enterprise infrastructure construction is more and more important, many customers are considering double export or three export link backup. How to reflect the advantages of double export, below introduces the configuration and principle of standard double export.
Principle: use the static routing dispatch, guarantee when accessing to all unicom's network segment, the next-hop is the unicom gateway; Non unicom (such as telecommunication, etc.) network segment’s next-hop is the telecom gateway. (unicom's network segment is less than telecom)
Take unicom and telecommunication double exports for example, because of the network server will distribute in unicom or telecommunications network, if through unicom export access to telecommunications server, it will be in unicom and telecom's total exports around a circle and then access the unicom server, such the delay will be very big, and can't reflect the advantage of double export.
