Nexus: VXLAN flood-and-learn with static ingress replication

L1 and L2 are leaves joined only by a routed underlay (OSPF through S1). Both have hosts in VLAN 10. Stretch VLAN 10 across the underlay with VXLAN: map it to VNI 10010 and replicate broadcast and unknown traffic to the other VTEP by unicast.

Objectives

The simulator ticks each one as soon as the network meets it.

On L1 and L2 enable feature nv overlay and feature vn-segment-vlan-based, and map VLAN 10 to vn-segment 10010.
On both, create interface nve1: no shutdown, source-interface loopback0, member vni 10010.
Under member vni 10010 use ingress-replication protocol static with the other leaf’s loopback as peer-ip (L1 → 2.2.2.2, L2 → 1.1.1.1).
show nve peers on L1: 2.2.2.2 is Up, learned in the data plane (DP).
Ping PC2 (192.168.10.20) from PC1.
