EVPN Proxy ARP and ARP Suppression, and Proxy NDP and NDP Suppression
Proxy Address Resolution Protocol (ARP) and ARP suppression, and proxy Neighbor Discovery Protocol (NDP) and NDP suppression are supported as follows:
MX Series routers and EX9200 switches
Starting with Junos OS Release 17.2R1, MX Series routers and EX9200 switches that function as provider edge (PE) devices in an Ethernet VPN-MPLS (EVPN-MPLS) or Layer 3 VXLAN gateways in an Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) environment support proxy ARP and ARP suppression, and proxy NDP and NDP suppression on an integrated and routing (IRB) interface.
Starting with Junos OS Release 17.4R2, MX Series routers and EX9200 switches support proxy ARP and ARP suppression, and proxy NDP and NDP suppression on non-IRB interfaces. Junos OS Release 17.4R2 also introduces the ability to limit the number of media-access-control (MAC)-IP address bindings that can be learned on these Juniper Networks devices.
QFX10000 switches
Starting with Junos OS Release 17.3R1, QFX10000 switches that function as Layer 3 VXLAN gateways in an EVPN-VXLAN environment support proxy ARP and ARP suppression, and proxy NDP and NDP suppression on an IRB interface.
Starting with Junos OS Release 19.1R1, QFX10000 switches that function as Layer 2 VXLAN gateways in an EVPN-VXLAN environment support proxy ARP and ARP suppression, and proxy NDP and NDP suppression on a non-IRB interface. You can also limit the number of MAC-IP address bindings that can be learned on these switches.
QFX5100, QFX5200, and QFX5110 switches—Starting with Junos OS Release 18.1R1, QFX5100 and QFX5200 switches that function as Layer 2 VXLAN gateways in an EVPN-VXLAN environment support proxy ARP and ARP suppression, and proxy NDP and NDP suppression on non-IRB interfaces. QFX5110 switches that function as Layer 2 or 3 VXLAN gateways in an EVPN-VXLAN environment support proxy ARP and ARP suppression, and proxy NDP and NDP suppression on IRB interfaces and non-IRB interfaces. You can also limit the number of MAC-IP address bindings that can be learned on these switches.
In Junos OS Releases you could configure the no-arp-suppression statement
to turn off suppressing ARP packets and NDP packets. However, starting in Junos OS Release
19.1R1, that statement is hidden in the Junos CLI.
This feature reduces the flooding of ARP and NDP messages in the EVPN network, resulting in a more efficient use of core bandwidth. By default, proxy ARP and ARP suppression and proxy NDP and NDP suppression are enabled.
When limiting the number of MAC-IP address bindings that can be learned, the limit can be configured globally or for a specific routing instance, bridge domain, VLAN, or interface. After the specified limit is reached, no additional entries are added to the MAC-IP binding database. You can also specify a timeout interval for MAC-IP address bindings.
Proxy ARP and NDP snooping are enabled by default for all EVPN-MPLS or EVPN-VXLAN bridge domains and VLANs. ARP or NDP packets generated from a local customer edge (CE) device or Layer 2 VXLAN gateway are snooped. ARP and NDP packets generated from a remote PE device or Layer 3 VXLAN gateway through core-facing interfaces, however, are not snooped.
Both IRB and non-IRB interfaces configured on a PE device or a Layer 2 or 3 VXLAN gateway deliver ARP requests and NDP requests. When one of these devices receives an ARP request or NDP request, the device searches its MAC-IP address bindings database for the requested IP address. If the device finds the MAC-IP address binding in its database, it responds to the request. If the device does not find the MAC-IP address binding, it takes the following action:
If the device is running Junos OS Releases 17.2Rx or 17.3Rx, the device swaps the source MAC address with the MAC address of the interface on which the request was received and sends the request to all interfaces.
If the device is running Junos OS Releases 17.4R1 or later, the device leaves the source MAC address as is and sends the request to all interfaces.
Even when a PE device or a Layer 2 or 3 VXLAN gateway responds to an ARP request or NDP request, ARP packets and NDP might still be flooded across the WAN. ARP suppression and NDP suppression prevent this flooding from occurring.
Proxy ARP and ARP suppression and proxy NDP and NDP suppression are supported in the following scenarios:
Single-homed devices in active mode—EVPN-MPLS and EVPN-VXLAN
Multihomed devices in active-active mode—EVPN-MPLS and EVPN-VXLAN
Multihomed devices in single-active mode—EVPN-MPLS only
In a multihoming active-active scenario, the database of MAC-IP address bindings are synchronized between the PE device or Layer 2 or 3 VXLAN gateway that act as the designated forwarder (DF) and non-designated forwarder (non-DF).
