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 .
