Active/Standby over 2 Datacenters

I've 2 datacenters, I want to put an ASA at each, in Active/Standby configuration.

I'll need to link the VLANs across the 2 sites to enable this to work.

I've been told that this is poor design, can anyone clarify this as I can not see any other method of doing this.

For info. I'll have the same Internet subnet at both sites to the same ISP, the inter-site links are 2 x 1Gbs fibre between 6500s

I would only have one 6500 at each site and switch off spanning tree

any help appreciated

Regards Tony

Re: Active/Standby over 2 Datacenters

what you need to consider is the link the state link and the failover link.

I have one with mpls carrying the link ( riding on static route) but will preffer a bridge if possibel.

Make the switch port connected to the lan failover and state link port fast, turn off bpdu and have a good feed.

Better to use physical interfaces
