  ~ resource "equinix_fabric_routing_protocol" "direct" {
        id              = "90e96ef8-75a1-4311-b466-53cbaf5e1df3"
        name            = "direct_rp"
        # (7 unchanged attributes hidden)

      - direct_ipv6 {
            # (1 unchanged attribute hidden)
        }

        # (1 unchanged block hidden)
