EVPN-VXLAN additional features support (ACX7100)
VLAN-based and VLAN bundle MAC-VRF service types (only VLAN-aware bundle service type was supported previously). (See MAC-VRF Routing Instance Type Overview.)
Spine role with CRB overlays.
Note:We don’t support overlapping VLANs between different virtual routing and forwarding (VRF) instances.
BPDU protection in EVPN-VXLAN. (See Understanding BPDU Protection for EVPN-VXLAN.)
Preference based DF election. (See Designated Forwarder Election.)
EVPN BGP policy options support for control plane.
Service provider style interface configuration with VXLAN, including:
Encapsulation types
ethernet-bridge
,extended-vlan-bridge
, andflexible-ethernet-services
. (See encapsulation.)Flexible VLAN tagging for single- and dual-tagged logical interfaces on the same port.
Q-in-Q. (See Examples: Tunneling Q-in-Q Traffic in an EVPN-VXLAN Overlay Network.)
(See Understanding Flexible Ethernet Services Support With EVPN-VXLAN.)
Extensions to enterprise style interface configuration support with VXLAN, including:
Trunk interfaces with flexible Ethernet services and flexible VLAN tagging.
Multiple trunk interfaces on the same port.
(See Understanding Flexible Ethernet Services Support with EVPN-VXLAN.)
Layer 2 (L2) and Layer 3 (L3) logical interfaces on the same port, with L2 logical interfaces as part of the VXLAN VLAN or tenant VLANs.
