I have a query re, a network I'm currently working on. Until recently the network was configured with layer 2 switches at the access layer with HSRP running at the distribution layer (3, running OSPF) for the data and VLAN's.
Recently they have moved over to using layer 3 (OSPF) at the access layer, with new data and voice VLAN's. Each new access switch stack (multiple 3750's in place of a single 4006) is therefore configured with legacy and new VLAN's.
No HSRP is configured for the new data VLAN's. Inorder to clean up the rationalize the HSRP configuration of rhte new and old VLAN's is it possible or neccessary to configure HSRP for the new VLAN's at either access or distribution layer since OSPF would take care of providing for link redundancy in the event of switch or link failure ??
