  • Stateless address autoconfiguration (SLAAC) snooping over a Layer 2 EVPN-VXLAN gateway (EX4300-MP and EX4300-MP VC)—Starting in Junos OS Release 21.2R1, you can enable SLAAC snooping on EX4300-MP switches in an Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) deployment. We support SLAAC snooping on CE-facing L2 interfaces. IPv6 clients using SLAAC for dynamic address assignment are validated against the SLAAC snooping binding table before being allowed access to the network.
