This makes it possible to deliver a better experience to broadband users who are simultaneously accessing internet applications or files.

Does BGP load balance by default?

By default, Border Gateway Protocol (BGP) selects only a single best path and does not perform load balancing.

How does BGP do load balancing?

The BGP Multipath Load Sharing for eBGP and iBGP feature allows you to configure multipath load balancing with both external BGP (eBGP) and internal BGP (iBGP) paths in Border Gateway Protocol (BGP) networks that are configured to use Multiprotocol Label Switching (MPLS) Virtual Private Networks (VPNs).

What is dual WAN load balancing?

Dual-WAN and multi-WAN load balancing is where two or more Broadband connections (ADSL, Cable, Fibre etc) are connected to a dedicated load-balancing router’s WAN port and Internet traffic optimally managed across the WAN connections.

Is a load balancing router worth it?

While the combination of two modems with a load-balancing router may not be the cheapest option available, it will provide outstanding security, performance and download speeds. Compared with true bonding solutions, ongoing costs will be lower.

What is DNS based load balancing?

DNS-based Load Balancing is the practice of configuring a domain in the Domain Name System (DNS) such that client requests to the domain are distributed across a group of servers. A domain can correspond to a website, a mail system, a print server, or another service that is made accessible via the Internet.

Does BGP support equal cost load balancing?
