Using the cisco-avpair="lcp:interface-config" RADIUS Attribute Chapter 6 Broadband Scalability and Performance Setting the VRF and IP Unnumbered Interface Configurations in Virtual Interface Templates You can specify one VSA value in a user profile on RADIUS and another value locally in the virtual template interface. The Cisco ASR 1000 Series Router clones the template and then applies the values configured in the profiles it receives from RADIUS, resulting in the removal of any IP configurations when the router applies the profile values. Redefining User Profiles to Use the ip:vrf-id and ip:ip-unnumbered VSAs The requirement of a full virtual access interface when using the lcp:interface-config VSA in user profiles can result in scalability issues, such as increased memory consumption. This situation is especially true when the Cisco ASR 1000 Series Router attempts to apply a large number of per-user profiles that include the lcp:interface-config VSA. Therefore, when updating your user profiles, we recommend that you redefine the lcp:interface-config VSA to the scalable ip:vrf-id and ip:ip-unnumbered VSAs. The following example shows how to redefine a VRF named newyork using the ip:vrf-id VSA: Change: Cisco:Cisco-Avpair = "lcp:interface-config=ip vrf forwarding newyork" To: Cisco:Cisco-Avpair = "ip:vrf-id=newyork" The following example shows how to redefine the Loopback 0 interface using the ip:ip-unnumbered VSA. Change: Cisco:Cisco-Avpair = "lcp:interface-config=ip unnumbered Loopback 0" To: Cisco:Cisco-Avpair = "ip:ip-unnumbered=Loopback 0" Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide 6-8 OL-16506-10
