implement Network infrastructure (routing , redundancy, Load Balancing)

[Jose Mourinho]

Hi All,

First i'm newbie so many considier about the network infrastructure.

i have just 5 vlan (10,20,30,40 and 100 for MGT)

I have 1 router, 2 core , 2 distribute and 2 access.

My cable connect all are trunk.

i'm confuse that vtp, vlan ,routing (ospf) ,hsrp ,stpwhich i should put in, i mean i'm have reading some document said that vtp should in core but some as different in distribute, i have attach file the diagram, but i think may be i need input more config just don't know what is the best for this diagram for logging and troubleshoot.

Hello,

basically:

VTP (VLAN Trunking Protocol) is used on switches to make sure that VLANs across all switches are the same. You configure a VLAN on the VTP server, and it gets propagated to the VTP clients

If you have just one router, you don't need OSPF or HSRP

STP is used for the links between switches to prevent loops.

This is a Packet Tracer file, post the project (save it as  .pkt and rename it to .jpg, otherwise you cannot upload)...

First thannk you for your respond
but my confuse is the place to put it, example i know what vtp is, but i don't know for best performance i should put it in core layer or distribute layer, same hsrp, and any technology i have miss for my diagram, because i'm new so i don't know all technology of cisco to applie my network.
Thanks

you could decide to run HSRP on your core switches if the function as default gateway for your vlans/subnets

Thank you for your respond,
but i don't know "if the function as default gateway for your vlans/subnets" mean, about hsrp, i think it should for core and distribute right ? i have vpn outsite too so i think ospf is still need

Hi,

As I am understanding that you are confused on the network diagram. You want to know that where you should configure the L3 routing and where L2 routing. There are many factors will put the effect on network designing and design to configure routing. As I am designing networks for my clients, I need to discuss with the client on many points.

I am going directly to your network diagram. You have Core, Distribute and access layers. I advised:

1. Configure Dynamic routing (OSPF) between router to the core switch. 

2. Distributor switch must send the summary routes to the core switch.

3. All ACL or other thing must be applied to distributer switch routing.

4. VLAN configuration and VLAN routing must be configured on distributer switch routing. Means now your distribute layer is working with L3 routing and L2 as well.

5. VTP server must be on distributer layer switches and client on access layer.

6. Access layer uplink port must be as a trunk port.

7. Distributer layer uplink must be in L3 mode (direct with no switchport command or with SVI). 

8. STP Root must be on distributer layer etc.

Sorry your answer is very helpful, but just i'm said i'm newbie so can't understanding all ,
please help me
"Distributer layer uplink must be in L3 mode (direct with no switchport command or with SVI). "
i don't know what it mean and about link between core and dis it will use trunk ? ,and router with core it will interface ip ? 

about HSRP i will config it between two core and distribute too ? any suggest from you more config for performance or optimize Sir?

HI,

"i don't know what it mean and about link between core and dis it will use trunk ? ,and router with core it will interface ip ?"

No, We are not using trunk port because there will no VLAN or STP is coming in the picture. Here we are playing with a routing protocol as OSPF. So We can make switch port from L2  to L3 port with a single command "No Switchport" but some switch models are not supported to this command then we need to create an SVI in the switch and assign to the interface which is connected to the uplink device.

Q: about HSRP i will config it between two core and distribute too ? any suggest from you more config for performance or optimize Sir? 

Ans: I am not involved the HSRP in the design because you are going with OSPF routing protocol. If you don't want to go with dynamic routing then you can go with HSRP but HSRP again having some limitation as no load-balancing.

Very clear for newbie and not good for english as me
