I have two new 6509E's in my network.

I would like to configure them in HA mode to reduce Failover time.

Please let me know the options.

Thanks in Advance

Hi ,

We do not have redundant Sup in 6509E switch.

I want to configure 6509E to reduce failover and convergence time.

What is an over all topology. Do you have a three tier architecture (Access-Distribution-core) or 2- tier archi( Collapsed Access/distri-core or access-collapsed disti/core). The over-all design recommendation depends on the final architecture.

If you have a 3-tier archi, then run RPVST+ from access-distribution layer and run EIGRP or OPSF at the core layer.You can run MHSRP at the distribution layer if you have dual chassis design. If you have a single chassis with redundant sup run NSF/SSO between the redundant sup's.

If you have a tier-2 architecture, then run RPVST+ and MSHRP at the core layer and RPVST+ at the access layer.Multiple HSRP will give you the HA between the 2 chassis for multiple vlans.



HTH,Please rate if it does.
