BGP implementation

dabur10376004 — Tue, 12 Mar 2019 06:30:22 GMT

Hi,

we have 3 internet Links Like ISP 1, ISP 2 & ISP 3.

ISP 1---> ASA1---> Core switch

ISP 2---> ASA2---> Core switch

ISP 3---> ASA3---> Core switch

we have different services as per below.

on ISP 1 ASA natted servers (Like mail, web server)

on ISP 2 ASA natted servers (Like mail, Botreeserver)

on ISP 3 ASA Natted (Like Lync, SAP & business application server)

now ISP 1 link got down then mail & web servers are not accessible from internet & same issue with other ISP.

so we are planning to implement BGP for availability of all services every times from internet.

After getting APNIC ip pool, we will implement.

we have following 3 question as below:

1. what is the best practice of BGP implementation.

2. ISP 1 40 Mbps, ISP 2 60 Mbps & ISP 3 60 Mbps. After BGP implementation can we put QOS for bandwidth restriction (lets suppose its utilization will not reach beyond 30 Mbps) for one proxy ip so that no any link get overutilized. the same QOS will apply on all three Internet router.

3. is any other mechanism apart from BGP?

Thanks

Hi,Can we achieve Load

Hi,

Can we achieve Load balancing through BGP in term of incoming traffic (from outside to inside) & outgoing traffic (from inside to outside) or BGP only support for Link redundancy.

Hi,is BGP is doing load

Hi,

is BGP is doing load balancing or not , or only for link redundancy purpose.

Thanks
