VLAN

VLAN ID definable per interface and routing context (4094 IDs)

Q- in- Q tagging

Support of layered 802.1q VLANs

Advanced Routing and Forwarding

Separate processing of 8 contexts due to virtualization of the routers. Mapping to VLANs and complete independent

NTP

NTP client and SNTP server, automatic adjustment for daylight- saving time

Policy- based routing

Policy- based routing based on routing tags. Based on firewall rules, certain data types are marked for specific routing, e.g. to 
particular remote sites or lines.

Dynamic routing
