Best Practices for Own APNIC IP pool with Two ISPs

[kumarmh91282]

Hi All,

I was wondering what is the best practices followed for Enterprise  WAN connections in the following scenario

1) Own APNIC Public IP pool

2) TWO ISPs for Redundancy (Multi-homed)

3)  ISR routers being used for BGP with both the ISPs  (Edge routers)

4) Firewall used behind ISR routers.

What would be the ideal topology in this scenarios, requirement

1) Dual ISP failover and  Load sharing

2) Internal Application  are hosted on internet with 1-to-1 nat

1) Dual ISP failover and  Load sharing

Look at the below example BGP Load share between ISP and Failover.

2) Internal Applications are hosted on the internet with 1-to-1 nat

Behind these Routers ?  - you need to Play DNS and hardware LoadBaancers
