We are in the process of setting up a WAN environ using MPLS from two different providers; sites are located in the US & UK using either T1/E1 connections for small offices and T3/E3 for the two large offices. Each MPLS link has a dedicated router (2821 E1/T1 or 3845 E3/T3) with iBGP running between them and eBGP to the provider.
Our goal is to have redundancy + load sharing between the two links. We will also look to getting QoS in place for business critical traffic i.e Citrix; SQL; Oracle & email & in the future voice traffic.
How do we go about setting up load sharing / redundancy between the two providers using BGP or any other method? Any suggestions or links to sample configs will be most appreciated.
Thanks in advance!
