1) Customer should have registered with the own IP Block & AS No# with RIPE / APNIC departments. Because, BGP Load-sharing with different providers is possible only if the above case available
2) The decision on the WAN Setup is upto your organizations IT scope. Either implement the the LINKS on the same Router (or) to avoid SPOF (single poinf of failure) causes, implement the links on the different CE Perimeter Routers
3) The recommendation is to use the tradational BGP dual homing and it is more effective itself.
If your prefer to optimze / monitor your WAN link utilization and others means implement TAP boxes in the Network for monitoring, where this will mirror the complete Traffic and the Riverbed Kind of Equipments to Optimze the WAN Link utilization across Backbone.
So, in case of going for BGP dual homing what kind of coordination needs to take place between the ISPs themselves after purchasing the public IP block? I am not sure if there is a regulation in my country for ISPs to speak and coordinate with each other?
On the other hand, when using multiple perimeter routers for BGP dual homing, is there any way to detect link errors to switch from one router to another in case of link errors/failures and how can this be implemented?
I would go for the F5's GTM to multi-home. with the F5's do you not need to go through the long process to register for AS Number and to be honest you dont even need to own your own IP Block. You can use IP Block provided by the providers.
The F5 BIG-IP Link Controller offers an easier-to-manage solution for establishing redundant links, preventing outages that result from a single point of failure. It monitors availability and performance for multiple network connections something BGP cannot do. BIG-IP Link Controller directs traffic over the best link and ISP, ensuring the highest possible QoS and speed for users.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
