On our Head Quarter buildings we need to upgrade to 10Gbps connections and avoiding single point of failure nodes also.
Refering to attached topo please, what equipments do you suggest invoking?
-must have at least 2x 10Gbps interfaces
-must be hotstandby (redundancy/failover) protected but with one single Fo connection per path.
Any suggest will be very helpful.
Thank you for your time.
don't neglect the physical elements if you need to avoid single points of failure. You can design the network to have redundancy and no single points of failure, but if a backhoe takes out both circuits down the street .....
i.e. separate physical entrances into the buildings, perhaps CO diversity for each circuit, etc. You need to work with your Telco(s) to ensure that, they too, are not a single point of failure. Even selecting two different Telcos may not help if they are using the same CO. Something to consider.
