Hi SK,

Hi SK,

1. Do I plan network design like upper?

Ans: If you ask me as a Network designer, It needs more work. You will L3 switch in stack mode and use HSRP on Router only. 

2. I should configure HSRP on Router and L3 switches

Ans: No, Practically it is not advisable to configure HSRP on both layers of Network. Please configure HSRP on Router only.

Thank you Deepak!

Thank you Deepak!

1. Stack mode : Is this meaning that connecting each other(L3 switches) ?

2. Could I ask you why I should configure HSRP on Router only...?

Please tell me the reason....,, more specifically..

Thank you

Hi

Hi

configure it on the router as there the wan facing devices

if your using HSRP maybe think about GLBP instead it can do the same thing but use multiple physical gateways at same time

http://blog.ine.com/2008/04/24/glbp-explained/

or If you use HSRP you could use IP Sla with tracking on each router and track an upstream route for failover tied into your hsrp config

You mean.

You mean.

1. You should use GLBP instead of HSRP.

2. but, if you must HSRP, you should IP SLA

don't you mark?

Hi Soon

Hi Soon

1 im not saying you have to use but think of it as an option if your using a FHRP , you can use both gateways at the same time with GLBP while in HSRP one will always be standby , Cisco equipment and ISP circuits are expensive to just have sitting in standby mode , using GLBP allows you to use everything at same time

2 Yes I would use sla with HSRP and track a route upstream for failover if that's the way you go

1. Do I plan network design

1. Do I plan network design like upper?

If not, please recommend more better.

Assuming none of your 2960s support stacking, you would probably want a trunk between your two L3 switches  You might want such a trunk link to have more bandwidth then your other links (which might be provided by Etherchannel.)

You would want one or both of your L3 switches to be the active gateways.

You would want your L3 switches to be the STP root and backup roots.  The root for a VLAN should be on the same L3 switch as the active gateway.

2. I should configure HSRP on Router and L3 switches.

Do I configure virtual IP on Router and L3 respectively?

I would suggest not, as I've suggested using the L3 switches as the gateways.

I would suggest routing between the L3 switches and the routers.  There are several routing topologies that could be used, but perhaps just p2p on each L3<>2911 would be best.

Thank you Joseph,

Thank you Joseph,

In your opinion, I would want to know "p2p"

What do you mean by that?

Sorry, p2p means point-to

Sorry, p2p means point-to-point.  Often configured with a /30, some routing protocols also support configured with a /31.
