Pls give me some advice in designing the corporate lan
(The main goal of the setup is high availability)
(Look at the attachement)
Let's start from the bottom. We have four 2950 switches at the access layer.
And two 3560 switches at the distribution layer
There is one more 3560 switch (and we are planning to buy two 3750 switches)
I've got the following ideas:
Access layer switches will be connected to the distribution layer via 2 links. Default gateways will be reserved via HSRP on the distribution 3560 switches.
(Perhaps I will divide the gateways for different vlans between 3560 to effectively utilize the links)
There will be L3 links between two 3560, and between 3750 stack and each 3560.
Thought about running OSPF between this switches. But doubt about IOS featureset on 3750.Maybe there are some other optimal design setups if it is not possible to run dynamic routing between this switches?
Servers will be connected to the 3750 stack via Etherchannels.
There will also be HSRP link between WAN routers and the 3750 stack.
Pls share your opinion about my setup.
Maybe there are some best practices?
