Per VRF AAA

First Published: June 4, 2001
Last Updated: January 4, 2010

The Per VRF AAA feature allows ISPs to partition authentication, authorization, and accounting (AAA) services on the basis of Virtual Private Network (VPN) routing and forwarding (VRF) instances, allowing their customers to control some of their own AAA services.

The list of servers in server groups is extended to include the definitions of private servers in addition to references to the hosts in the global configuration, allowing access to both customer servers and global service provider servers simultaneously.

For Cisco IOS Release 12.2(15)T or later releases, a customer template can be used, which may be stored either locally or remotely, and AAA services can be performed on the information that is stored in the customer template. This feature has also been referred to as the Dynamic Per VRF AAA feature.

Prerequisites for Per VRF AAA

Before configuring the Per VRF AAA feature, AAA must be enabled. See "How to Configure Per VRF AAA" section for more information.

Restrictions for Per VRF AAA

•This feature is supported only for RADIUS servers.

•Operational parameters should be defined once per VRF rather than set per server group, because all functionality must be consistent between the network access server (NAS) and the AAA servers.

•The ability to configure a customer template either locally or remotely is available only for Cisco IOS Release 12.2(15)T and later releases.

Information About Per VRF AAA

When you use the Per VRF AAA feature, AAA services can be based on VRF instances. This feature permits the Provider Edge (PE) or Virtual Home Gateway (VHG) to communicate directly with the customer's RADIUS server, which is associated with the customer's Virtual Private Network (VPN), without having to go through a RADIUS proxy. Thus, ISPs can scale their VPN offerings more efficiently because they no longer have to use RADIUS proxies and ISPs can also provide their customers with additional flexibility.

•How Per VRF AAA Works

•AAA Accounting Records

•New Vendor-Specific Attributes

How Per VRF AAA Works

To support AAA on a per customer basis, some AAA features must be made VRF aware. That is, ISPs must be able to define operational parameters—such as AAA server groups, method lists, system accounting, and protocol-specific parameters—and bind those parameters to a particular VRF instance. Defining and binding the operational parameters can be accomplished using one or more of the following methods:

•Virtual private dialup network (VPDN) virtual template or dialer interfaces that are configured for a specific customer

•Locally defined customer templates—Per VPN with customer definitions. The customer template is stored locally on the VHG. This method can be used to associate a remote user with a specific VPN based on the domain name or dialed number identification service (DNIS) and provide the VPN-specific configuration for virtual access interface and all operational parameters for the customer AAA server.

•Remotely defined customer templates—Per VPN with customer definitions that are stored on the service provider AAA server in a RADIUS profile. This method is used to associate a remote user with a specific VPN based on the domain name or DNIS and provide the VPN-specific configuration for the virtual access interface and all operational parameters for the AAA server of the customer.

Note The ability to configure locally or remotely defined customer templates is available only with Cisco IOS Release 12.2(15)T and later releases.

AAA Accounting Records

The Cisco implementation of AAA accounting provides "start" and "stop" record support for calls that have passed user authentication. Start and stop records are necessary for users employing accounting records to manage and monitor their networks.

New Vendor-Specific Attributes

The Internet Engineering Task Force (IETF) draft standard specifies a method for communicating vendor-specific information between the network access server and the RADIUS server by using the vendor-specific attribute (VSA) attribute 26. Attribute 26 encapsulates VSAs, thereby, allowing vendors to support their own extended attributes otherwise not suitable for general use.

The Cisco RADIUS implementation supports one vendor-specific option using the format recommended in the specification. Cisco's vendor-ID is 9, and the supported option has vendor-type 1, which is named "cisco-avpair." The value is a string of the following format: 

protocol : attribute sep value *

"Protocol" is a value of the Cisco "protocol" attribute for a particular type of authorization. "Attribute" and "value" are an appropriate attribute-value (AV) pair defined in the Cisco TACACS+ specification, and "sep" is "=" for mandatory attributes and "*" for optional attributes. This format allows the full set of features available for TACACS+ authorization to be used also for RADIUS.

Table 1 summarizes the VSAs that are now supported with Per VRF AAA.

Table 1

VSA Name
Value Type
Description

Note Each VSA must have the prefix "template:" before the VSA name, unless a different prefix is explicitly stated.

account-delay

string

This VSA must be "on." The functionality of this VSA is equal to the aaa accounting delay-start command for the customer template.

account-send-stop

string

This VSA must be "on." The functionality of this VSA is equal to the aaa accounting send stop-record authentication command with the failure keyword.

account-send-success-remote

string

This VSA must be "on." The functionality of this VSA is equal to the aaa accounting send stop-record authentication command with the success keyword.

string

This VSA must be "access-req." The functionality of this VSA is equal to the radius-server attribute 44 include-in-access-req command.

ip-addr

string

This VSA specifies the IP address, followed by the mask that the router uses to indicate its own IP address and mask in negotiation with the client; for example, ip-addr=192.168.202.169 255.255.255.255

ip-unnumbered

string

This VSA specifies the name of an interface on the router. The functionality of this VSA is equal to the ip unnumbered command, which specifies an interface name such as "Loopback 0."

ip-vrf

string

This VSA specifies which VRF will be used for the packets of the end user. This VRF name should match the name that is used on the router via the ip vrf forwarding command.

ppp-acct-list

string

This VSA defines the accounting method list that is to be used for PPP sessions.

The VSA syntax is as follows: "ppp-acct-list=[start-stop | stop-only | none] group X [group Y] [broadcast]." It is equal to the aaa accounting network mylist command functionality.

The user must specify at least one of the following options: start-stop, stop-only, or none. If either start-stop or stop-only is specified, the user must specify at least one, but not more than four, group arguments. Each group name must consist of integers. The servers in the group should have already been identified in the access-accept via the VSA "rad-serv." After each group has been specified, the user can specify the broadcast option.

ppp-authen-list

string

This VSA defines which authentication method list is to be used for PPP sessions and, if more than one method is specified, in what order the methods should be used.

The VSA syntax is as follows: "ppp-authen-list=[groupX | local | local-case | none | if-needed]," which is equal to the aaa authentication ppp mylist command functionality.

The user must specify at least one, but no more than four, authentication methods. If a server group is specified, the group name must be an integer. The servers in the group should have already been identified in the access-accept via the VSA "rad-serv."

ppp-authen-type

string

This VSA allows the end user to specify at least one of the following authentication types: pap, chap, eap, ms-chap, ms-chap-v2, any, or a combination of the available types that is separated by spaces.

The end user will be permitted to log in using only the methods that are specified in this VSA.

PPP will attempt these authentication methods in the order presented in the attribute.

ppp-author-list

string

This VSA defines the authorization method list that is to be used for PPP sessions. It indicates which methods will be used and in what order.

The VSA syntax is as follows: "ppp-author-list=[groupX] [local] [if-authenticated] [none]," which is equal to the aaa authorization network mylist command functionality.

The user must specify at least one, but no more than four, authorization methods. If a server group is specified, the group name must be an integer. The servers in the group should have already been identified in the access-accept via the VSA "rad-serv."

Note The RADIUS VSAs—rad-serv, rad-server-filter, rad-serv-source-if, and rad-serv-vrf—must have the prefix "aaa:" before the VSA name.

rad-serv

string

This VSA indicates the IP address, key, timeout, and retransmit number of a server, as well as the group of the server.

The VSA syntax is as follows: "rad-serv=a.b.c.d [key SomeKey] [auth-port X] [acct-port Y] [retransmit V] [timeout W]." Other than the IP address, all parameters are optional and can be issued in any order. If the optional parameters are not specified, their default values will be used.

The key cannot contain any spaces; for "retransmit V," "V" can range from 1-100; for "timeout W," the "W" can range from 1-1000.

rad-serv-filter

string

The VSA syntax is as follows: "rad-serv-filter=authorization | accounting-request | reply-accept | reject-filtername." The filtername must be defined via the radius-server attribute list filtername command.

rad-serv-source-if

The Per VRF AAA feature allows authentication, authorization, and accounting (AAA) on the basis of Virtual Private Network (VPN) routing and forwarding (VRF) instances. For Cisco IOS Release 12.2(15)T or later releases, you can use a customer template, which may be stored either locally or remotely, and AAA services can be performed on the information that is stored in the customer template.

In 12.2(1)DX, the Per VRF AAA feature was introduced on the Cisco 7200 series and the Cisco 7401ASR.

In 12.2(2)DD, the ip vrf forwarding (server-group) and radius-server domain-stripping commands were added.

The Per VRF AAA, Dynamic Per VRF AAA, and Attribute Filtering Per-Domain and VRF Aware Framed-Routes features were introduced in Cisco IOS Release 12.2(15)T. Also, the aaa authorization template command was added to this release.

In 12.4(2)T, the aaa accounting send stop-record authentication command was updated with additional support for AAA accounting stop records.

In 12.2(33)SRC, RADIUS Per-VRF Server Group feature was introduced.

In Cisco IOS Release 12.2(33)SXI, these features were introduced.

In Cisco IOS Release 12.2(33)SXH4, these features were introduced.

The following commands were introduced or modified: aaa accounting, aaa accounting delay-start, ip radius source-interface, radius-server attribute 44 include-in-access-req, server-private (RADIUS).


Glossary

AAA—authentication, authorization, and accounting. A framework of security services that provide the method for identifying users (authentication), for remote access control (authorization), and for collecting and sending security server information used for billing, auditing, and reporting (accounting).

L2TP—Layer 2 Tunnel Protocol. A Layer 2 tunneling protocol that enables an ISP or other access service to create a virtual tunnel to link customer remote sites or remote users with corporate home networks. In particular, a network access server (NAS) at the ISP point of presence (POP) exchanges PPP messages with the remote users and communicates by L2F or L2TP requests and responses with the customer tunnel server to set up tunnels.

PE—Provider Edge. Networking devices that are located on the edge of a service provider network.

RADIUS—Remote Authentication Dial-In User Service. RADIUS is a distributed client/server system that secures networks against unauthorized access. In the Cisco implementation, RADIUS clients run on Cisco routers and send authentication requests to a central RADIUS server that contains all user authentication and network service access information.

VPN—Virtual Private Network. A system that permits dial-in networks to exist remotely to home networks, while giving the appearance of being directly connected. VPNs use L2TP and L2F to terminate the Layer 2 and higher parts of the network connection at the LNS instead of the LAC.

VRF—Virtual Route Forwarding. Initially, a router has only one global default routing/forwarding table. VRFs can be viewed as multiple disjoined routing/forwarding tables, where the routes of a user have no correlation with the routes of another user.
