Network Design

[knaik99]

if I want to design network then I have two design then which one is better--

network details--

there are total 60 access layer switches--

network design one--

in this,I am using collapsed core i.e. Core1,2 & 3 (Model 4506-e with single sup 720 Card)

there is HSRP between core 1 & 2.

and on core3,We have written default route only which is going to HSRP of Core1&2 VIP.

and Core 1 &2 serves 20 access switches.

Core 1 & 3 serves 20 access switches

Core 2 &3 serves 20 access switches

for illustration,pic of my first design is attached so tell me whether this design is right or Pros & Cons.

Network design two---

there is only Core 1 & 2 with HSRP and I added Distribution layer with 2 devices in VSS.

Core1 & 2---Switch 4506 -e with HSRP

Distribution---2x Switch 4506 -e as VSS

and all 60 Switches are served from this VSS setup

for illustration,pic of my first design is attached so tell me whether this design is right or Pros & Cons.

and out of 2, which will you suggest

Design 2 is more acceptable design personally ( but got caveats that sup 720 is too old, suggest to have Sup-2T if possible,)

If you are not keen to deploy VSS, Do it also with out VSS - since VSS may have some operational challenges.

Thank you
Yes we are going to change sup card
But in second design
Distribution layer I.e .VSS is going to handle 67 access layer switches
traffic
And May I know disadvantage of VSS

As long as your supervisor higher version taken care, you are good.

VSS is like stacking, make 2 x 4500 physical in to one logical switch, but there are pros and cons in the real time experience.

if you are not famiiar and hands on with the VSS, i would suggest stay away.
