| SVDEntityRole |
|
| This textual convention denotes the role of a physical
entity with respect to selective VRF download feature.
'invalid': The role of the physical entity is unknown,
unconfigured, or the selective VRF download feature
has yet to calculate it.
'standard': The role of the physical entity has
interfaces configured in the default table and other
VRF tables. The selective VRF download feature
downloads all VRFs and prefixes to the physical entity.
'core': The role of the physical entity only has
interfaces configured in the default table. The
selective VRF download feature downloads all VRFs and
local customer prefixes to the physical entity.
'customer': The role of the physical entity only has
interfaces configured in VRF tables other than the
default. The selective VRF download feature downloads
all prefixes for locally provisioned VRFs.
'noInterest': The role of the physical entity does not
have interfaces configured in any VRF tables. The
selective VRF download feature does not download any
prefixes to the physical entity.
'vpnOnlyCustomer': The role of the physical entity is
for VPN-only customers (i.e., customers that do not need
access to global routes). The selective VRF download
feature downloads provisioned VRFs to the physical
entity, and it filters all BGP routes from the default
table. |

| ciscoSelectiveVrfDownloadMIB |
1.3.6.1.4.1.9.9.775 |
| This MIB module defines objects describing selective
VRF download. The selective VRF download feature makes
a best effort to download only those prefixes and labels
to a physical entity required to forward traffic through
the physical entity. The feature accomplishes this by
characterizing roles for physical entities baed on their
configuration.
Following terminology is introduced with selective VRF
download feature:
Core Facing A physical entity which has only core
facing interfaces (interfaces that
connect to other Provider/Provider Edge
devices).
Customer Facing A line physical entity which has one or
more customer facing interfaces
(interfaces that connect to Customer
Edge devices in different VRFs).
Local prefix A prefix that is received from a
Customer edge device connected to the
router in a configured VRF context.
Remote prefix A prefix received from another Provider
Edge device and is imported to a
configured VRF.

| csvdAdminEnable |
1.3.6.1.4.1.9.9.775.1.1 |
| This object specifies the desired state of selective
VRF download feature. When a managed system initializes,
it starts with csvdAdminEnable in the true(1) state. As a
result of either explicit management action or per
configuration information retained by the managed system,
csvdAdminEnable is then changed to false(2) state (or
remains in the true(1) state. |

1.3.6.1.4.1.9.9.775.1.2 |
| This object indicates the current operational state of
selective VRF download feature. If csvdAdminEnable is
changed then csvdOperEnable should change to the same
value after the external action is triggered. As an
external action implementations may require router reload
or switchover of the route-processor for the change to
take effect. |

recent occasion at which selective VRF download counters
suffered a discontinuity. The relevant counters are the
instances of any Counter32 objects contained in
csvdStateTable. If no such discontinuities have occurred
since the last re-initialization of the local management
subsystem, then this object contains a zero value. |

relationship on the entPhysicalTable, containing zero or
more rows each row in the entPhysicalEntity. If the
physical entity is capable of forwarding packets, it
contains a row for each address family it supports. |

each supported AFI when a new physical entity capable of
forwarding packets becomes operational. The system
destroys all the entries associated with the physical
entity when it goes away. |

| csvdStateEntityRole |
1.3.6.1.4.1.9.9.775.1.5.1.2 |
| This object specifies the selective VRF download role of
the physical entity. It can be updated based on interface
to VRF association change or ip-address assignment to an
interface belonging to the physical entity.
For example:-
- if no interfaces on a physical entity have IPv4 address
configured, then it would be in Customer Facing
Role for IPv4 address family.
- if no interfaces on a physical entity have IPv6 address
configured, then it would be in Not Interested
Role for IPv6 address family.
- now if the user adds an IPv4 address to an interface
in default VRF, then the physical entity would turn
Core-Facing for IPv4 AFI.
- if the user would have added this interface in a
named VRF, then the physical entity would have remained in
Customer-Facing for IPv4 AFI.
- if there are interfaces configured in both default
VRF and named VRFs then the physical entity would turn in
to Standard Role. |
