میتونید از ISP redundancy استفاده کنید
This topic describes how to enable Internet service provider (ISP) redundancy, which allows you to link two external network adapters to two different ISPs.
There are two ISP redundancy modes:
- High availability mode—Designates a primary link over which all outbound Internet traffic will flow, and a backup link that activates automatically if the first link fails.
- Load-balancing mode—Directs outbound Internet traffic between two ISP links concurrently, and sets the percentage of total Internet traffic per link. It also supports failover if one of the links fails.
