Administrator Guide

Usage Information
To enable routing of RRoCE packets, the VLAN ID is mapped to the default VLAN ID of 4095 and this mapping is
performed using VLAN translation. After VLAN translation, the RRoCE packets are considered in the same
manner as normal IP packets that received on L3 interface and routed in the egress direction. At the egress
interface, the VLAN ID is appended to the packet and transmitted out of the interface as a tagged packet with
the dot1Q value preserved. The dot1Q value is preserved only for egress interfaces that are associated with a
VLAN or a lite-subinterface . If a Layer 3 interface is configured without the encapsulation 802.1Q VLAN ID or is
an untagged interface in a VLAN , the dot1Q value is not preserved .
