## VXLAN/EVPN MAC Learning

### Check Learned MACs via VXLAN
```bash
# View all MAC addresses learned via VXLAN (Arista equivalent of Cisco's "show l2route evpn mac all")
show vxlan address-table

# Check MACs for specific VLAN
show vxlan address-table vlan <vlan-id>
```

### Check EVPN MAC-IP Routes
```bash
# View all EVPN Type 2 routes (MAC-IP advertisements)
show bgp evpn route-type mac-ip

# Check specific MAC or IP
show bgp evpn route-type mac-ip <mac-address>
show bgp evpn route-type mac-ip <ip-address>

# View with details (includes route distinguishers, extended communities)
show bgp evpn route-type mac-ip detail
```

### Check VXLAN VTEPs
```bash
# List remote VTEPs
show vxlan vtep

# Check VXLAN interface status
show interface Vxlan1

# View VXLAN flood lists for BUM traffic
show vxlan flood vtep

# Check VXLAN counters
show vxlan counters
```

### Verify ARP Learning for EVPN
```bash
# Check if switch has learned IP-to-MAC bindings
show ip arp

# For MAC+IP to be advertised in EVPN Type 2 routes, the switch must have
# ARP entries. If empty, only MAC-only routes will be advertised.
# ARP suppression/proxy requires MAC+IP routes to function.
```

## Devstack Deployment Issues
- Check network connectivity on trunk0: `ip link show trunk0`
