alias vlan interfaces on the ACE

I am getting up to speed the ACE module and seeing lots of cases where an alias is configured on both, the client and server side vlan interfaces. Is this a requirement?

Thanks..

The alias command is like HSRP in the MFSC. This way, you will be able to reach your ACE context even if your primary ACE module fails.

Thnx for your response. I can see how the alias concept would come in to play when configuring a fault tolerant vlan as part of the redundancy. Is it also commonly used for a vlan int on the ACE?

Thanks again

Re: alias vlan interfaces on the ACE

Hi,

Yes it is. If you have a pair of ACEs in routed mode, you should use aliases on your VLAN interfaces.

This VLAN address should then be used by your servers as default-gateway on the server side, and as next-hop for you upstream routers on client-side.

This way, if the primary ACE fails, the next-hop address and default-gateway of your upstream routers and servers don't have to be changed because the IP Address remains the same.

Take a look at following doc for configuration guidelines: http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A1/configuration/rtg_brdg/guide/vlansif.html#wp1034811

HTH,

Dario
