Dear Sir,

Deatails are as follows.

L2 Redundancy:

• Between two Backbone switch there are 3 nos of Links: One is Wireless Link using Canopy and Two 10 Gig are Fiber link which is maintained by STP. ( Primary Link will be 10Gig port because of low cost : 2 than Gig port cost : 4 )

• Between Backbone and Distribution Switch one link will be active and other link will be blocked by STP according to the path cost.

• Primary Root will be ESH (AS ESH side Backbone VLAN STP Priority : 16384 and at Prabhat side Backbone Vlan STP Priority will be 28672 )

L3 Redundancy:

• On both the Backbone Switch HSRP will be used on Backbone Vlan. (ESH side HSRP Priority will be 120 and at Prabhat side HSRP Priority will be 110.)

• Redundancy between TWO SUP on one chassis will be handled by SSO and Config-sync feature with SRM. (Only one SUP will be active at a time.)

I want to use two Ten Gidg Port using Fiber and one Gig port using Canopy Wireless between tweo CORE switches.

On Distribution there will not be HSRP . It is ok or not ?

Pls Reply ....

Hello Dipesh,

you have already a thread about this.

I've answered there.

Your design can be improved in several ways:

interconnection: adding link between distrib1 and core2

routing: moving to a dynamic routing protocol can change dramatically network capability to react to topology changes see the explanation in other thread.

Hope to help
