Servers on a new leaf cannot reach their VLAN across the fabric

A new leaf, LEAF3, was added to a Nexus VXLAN EVPN fabric for rack 3. The underlay is OSPF (process UNDERLAY, area 0) and the overlay is iBGP EVPN in AS 65000 with SPINE1 and SPINE2 as route reflectors. SRV3 (10.10.10.13) on LEAF3 is in VLAN 10, VNI 10010. It cannot ping SRV1 (10.10.10.11) on LEAF1 in the same VLAN. Servers on LEAF3 can reach each other, and both BGP EVPN sessions from LEAF3 to the spines are Established. Each leaf uses loopback0 for the router ID and BGP, and loopback1 as the VTEP source.
