We have a basic BGP setup in house to host our own dedicated subnet and AS with a single ISP.
This was setup by the previous tech with the help of the ISP several years ago.
Our company now wants to replace our BGP router with a pair of redundant Cisco routers and add a second peered ISP for failover.
What is the optimal configuration for this?
Should I run each of the two routers on one ISP each? or setup both ISPs on both devices?
How do I load balance the traffic between the two? or is it best to have them active/passive?
