Defined Types

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. See the following references for futher information: RFC 3813 - Multiprotocol Label Switching (MPLS) Label Switching Router (LSR) Management Information base (MIB), C. Srinivasan, A. Vishwanathan, and T. Nadeau, June 2004 RFC 4382 - MPLS/BGP Layer 3 Virtual Private Network (VPN) Management Information Base, T. Nadeau & van Der Linde, February 2006 Acronyms: VRF Virtual Routing and Forwarding VPN Virtual Private Network P Provider Core Device PE Provider Edge Device CE Customer Edge Device AFI Address Family Identifier CEF Cisco Express Forwarding

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.

  TruthValue  

csvdOperEnable 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.

  TruthValue  

csvdCounterDiscontinuityTime 1.3.6.1.4.1.9.9.775.1.4
This object indicates the value of sysUpTime on the most 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.

csvdStateTable 1.3.6.1.4.1.9.9.775.1.5
This table lists the state relating to the selective VRF download feature for each physical entity capable of forwarding packets. This table has an expansion dependent 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.

csvdStateEntry 1.3.6.1.4.1.9.9.775.1.5.1
An entry describes state relating to the selective VRF download feature. The system creates an entry each for 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.
