Configuring Radius; Configuration Examples For Half-Duplex Vrf - Cisco 10000-2P2-2DC Software Configuration Manual

Half-Duplex VRF

Configuring RADIUS

To configure the downstream VRF for an AAA server, enter the following Cisco attribute value:
cisco-avpair = "ip:vrf-id=vrf-name1 downstream vrf-name2"
where:
The vrf-name1 argument is the name of the VRF associated with the subinterface or virtual template
interface.
The vrf-name2 argument is the name of the downstream VRF into which all of the subscriber routes from
the AAA server are installed.
Instead of using the lcp:interface-config RADIUS attribute, we recommend that you use the ip:vrf-id
Note
RADIUS attribute when supported in Cisco IOS software. Unlike the lcp:interface-config attribute,
which causes full virtual interfaces to be used, the ip:vrf-id attribute causes virtual subinterfaces to be
used, which significantly improves scalability.
