Hi
We have two data centres A and B
Both are same in design
Datacentre A:
WAN router is connected to ------firewall-------firewall has many DMZ switches----------firewall internal interface is connected to core switch.....the core switch is connected to datacentre B via fibre and running OSPF (same vlan spanned)
Datacentre B:
Same as datacentre A
Design for high availability:
In datacentre A I am thinking that i would add a default static route pointing towards firewall internal interface on firewall.
I will add IP SLA and will ping the interface of provider router on WAN as soon as it fails, IP SLA will install a static route towards the second daatcentre internal firewall interface.
Is this a good design????
Do i have to add any Static routing on datacentre B???
this is tarffic going out for in traffic we will use BGP with service provider
please advise
