I am currently using a 24 port 3750 as a core switch hooked up to an ASA 5520 firewall. I am upgrading the switch to a 48 port 3750. Currently I am using OSPF on the switch and firewall to share routes. I started configuring the new 48 port to replace the old 24 port, but when I tried to turn on OSPF it told me the protocol was not included in the image.
1) How do I obtain an image that does have OSPF?
2) How do I load that image onto the new 48 port?
