DESCRIPTION
"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
IP addresses.
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
information:
* 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."
REVISION "201501110000Z"

aristaVrfMibConformance OBJECT IDENTIFIER
::= { aristaVrfMIB 2 }
-- Textual Convention
VrfName ::= TEXTUAL-CONVENTION
DISPLAY-HINT "100t"
STATUS current
DESCRIPTION
"A human-readable identifier assigned to every VRF. The
identifier is unique across all VRFs in the system."
SYNTAX OCTET STRING (SIZE (0..100))
VrfRouteDistinguisher ::= TEXTUAL-CONVENTION
DISPLAY-HINT "256a"
STATUS current
DESCRIPTION
"A route distinguisher as defined in [RFC4364], in the form
'<admin>:<local>', where <admin> is the administrator ID
(e.g., an AS number) and <local> is the locally assigned
number."
REFERENCE
"[RFC4364]"
SYNTAX OCTET STRING(SIZE (0..256))
VrfState ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The state of a specific VRF. When the administrator
configures a VRF on the system, it stays inactive until a
route distinguisher is assigned to it. Also, when the
administrator deletes a VRF, there can be a small delay
before the VRF is completely unconfigured from the system,
during which time its status becomes inactive."
