This MIB contains information related to Virtual
Routing and Forwarding (VRF).
VRF is a mechanism by which a single device can provide
independent routing instances. This allows customers to
virtually isolate network traffic, and also use overlapping
Layer3 or routed interfaces in the system will belong to
one VRF at a time. The datapath forwarding logic uses the
VRF membership of the input interface to determine a
specific forwarding table to use for routing the traffic.
VRF can also be used to isolate management traffic from
the rest of the data plane traffic.
This MIB module provides the following pieces of
* A table of all VRFs configured in the system
* A table that contains the VRF membership information
for all routed interfaces in the system by sparsely
augmenting the ifTable.
