VRF lite would certainly help for isolating the VLANS and can take care of the ACL's in the SVI.

Create VLANs and associate each vlan with a paricular VRF forwarding instance.

If you have 2 core/dist switches, connect the access switches to each core and enable uplinkfast. HSRP can be configured for VLANS for redundnacy.

We need more information abut your WAN topology to discuss OSPF routing

hi,

It's for the LAN .

We want to make a new topology

Like the hierarchical model.

1 core with 2 routers

3 distributions with 3750 ( 3*2 3750)

acces layer 2950

So ok for uplinkfast on the 2950,

we want hsrp in the distribution ( for 4 vlans

/disribution)

The link between the distribution and the core might be routed ports, so we need a routing protocol .

I'masking if hsrp and the routing protocol might be correlate and how
