TCP Load distribution with NAT

Im using NAT TCP load distribution, to load balancing two LDAP servers, but how can I avoid the use of a real server when it´s down??

Does NAT note this??

Re: TCP Load distribution with NAT

Hi,

I'm afraid that that is not possible. NAT TCP load distribution does not keep track of what servers are reachable so when the server goes down, NAT continues to translate to the server's address.

If you need features such as this, you need to look at using some form of Server Load Balancing (SLB). The following link describes the IOS SLB feature:

Hope that helps - pls rate the post if it does.

Re: TCP Load distribution with NAT

Thank you. But I´m using a VRF to route that SVI, and I don´t know how to associate the SLB protocol to that VRF.

I´ll appreciate if you know how to solve this

Thank you
