The distribution layer is responsible for routing traffic between the access layer and the core layer. A first-hop redundancy protocol is needed in the distribution layer when the design implements Layer 3 between the access switch and the distribution switch. This is because the first-hop redundancy protocol will provide redundancy for the default gateway, which is the IP address of the router that the hosts on the access switch use to reach the rest of the network.
