LAYER 2 SWITCH TOPOLOGY

Hi, This diagram is not for a real network as Im only practising using my knowledge on paper and do plan on practically setting this up at home via my 'Netgear router' as per diagram for practical experience not only from Cisco point of view but adding Win 2003 & Windows 2008 dns, dhcp etc and installing OS over the network, knowing that I have this time created a Network from scratch..!!

Qns.1 With the equipment I have and the specific ports available Ive created a Network diagram based around testing HSRP as I think it can only use 2 different subnets..?

Also Although I understand a 3 switch triangle ie root bridge, designated & root port etc.  Ive never connected switches together via a router as always just used as a 'hub' and no vlans when practising installing OS Pxe & ip helper-address via Win 2003 over network for practise..!

Qns2. Can someone advise on where Ive added the Vtp Server & Client root 4096 secondary 8192 & client 32768 with relevant 'root & designated ports' if they are correct or not - ?

Qns3.  Is there any other way of providing some other 'Fault-tolerance' specific to my hardware ?

You have a couple problems.

1) All VTP switches have to be on the same broadcast domain (network).
2) The routers will be able to provide HSRP to the hosts on Switch C. But not hosts on Switches A and B.

I would move Switches A and B to the inside on the routers and let the routers be your "edge" devices.

Hi I presume you mean move both Switches on the same side as each other ie 192.168.1.0/24 or 192.168.20/24 - ?

correction - 192.168.1.0/24 or 192.168.2.0/24...!

Hi, That was going to be my next drawing in another thread as the reason for asking about this thread is because Ive seen diagrams out their where the switches have been first instead of the Routers as mine also as the Firewall/CBAC part, but never understand why....

One reason could be a DMZ.

Although yes I do appreciate that my diagram is showing 2 broadcast domains when it should be on 1 as both my VTP Servers are supposed to be together as the other is the secondary root bridge..  So yes I can see my diagram was incorrect..

Oh ok I see what you mean ie One part of the networks could have the services such as DNS and the other would have the internal part of the network...

Hi Don,
Qns1. How do I make the 3600-A router the priority even though the VTP Server root 4096 is connected to 3600-A - ?

Don JohnstonInstructorCommented:
Routers don't do VTP. Switches only.

Hi Don, you sent me a pic - 37056508..! I know routers dont do VTP, but they can connect to them....  Dont forget I wish to use 'HSRP', but one of the routers will be the priority ..

Im assuming I would have to use a method to make a router more attractive..by adding bandwidth on a specific interface ie Higher bandwidth unless a lower bandwidth needs to be chosen because there maybe an issue on one of the routers so adding a route-map to point in direction could assist....?

Or maybe I would use 2 routing protocols such as rip & ospf:

3600-A
router rip
redistribute ospf 1 metric 50 50 0000 1 1500
distance rip 120 100

3600-B
router ospf 1
redistribute rip 50 metric 50 subnets

for eg although the above is based around 'eigrp & ospf' NOT 'rip & ospf' as I have guessed above..

What do you think ?

Hi Don, Ive just realised because Im using 'HSRP' it has already been prioritised so my last comment was irrelevant..!!
