Network setup
Need to setup a network with cisco switch / routers with the following criteria :
1. all access switches will connected to the distribution/core switch with redunancy in distribution switch. in case the primary distribution switch is down, the secondary switch will take up the role.
2. the primary / secondary switch will connect to internet access. Initally idea will have two different ISP provider, if one go down, the other will take up its work.
3. All servers will have its own VLAN. With several VLANs for different floor.
4. Only few access switches (in some floors) will need redunancy, similar to disribution switch.
What kinds of Cisco routers and switches will need in these scenario ? Is there any example how to configure these requirement, especially on the redunancy part.
Great thanks.

Tks, but really want to have some related configuration scenario (or simliar scenario) to visualize how it actually works.

Hi,
Please configure VRRP.The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork.
The protocol achieves this by creation of virtual routers, which are an abstract representation of multiple routers, i.e. master and backup routers, acting as a group. The default gateway of a participating host is assigned to the virtual router instead of a physical router. If the physical router that is routing packets on behalf of the virtual router fails, another physical router is selected to automatically replace it. The physical router that is forwarding packets at any given time is called the master router.
VRRP provides information on the state of a router, not the routes processed and exchanged by that router. Each VRRP instance is limited, in scope, to a single subnet. It does not advertise IP routes beyond that subnet or affect the routing table in any way. VRRP can be used in Ethernet, MPLS and token ring networks with Internet Protocol Version 4 (IPv4), as well as IPv6.

Will there be some configuration example for these two routers ?
What's the solution for the reduancy for the distribution / core switch that connecting to the access switches and the internet router ?

At switch level use LAGS for cable redundancy and at router level use HSRP.
Word of warning though, watch out for STP issues hiccups as you appear to have multiple loops.
