Configuring a VPN Routing and Forwarding Instance in BGP
Layer 3 (virtual private network) VPN can be configured only if there is an available Layer 3 VPN license
for the line card slot on which the feature is being configured. If advanced IP license is enabled, 4096 Layer
3 VPN routing and forwarding instances (VRFs) can be configured on an interface. If the infrastructure VRF
license is enabled, eight Layer 3 VRFs can be configured on the line card.
See the Software Entitlement on Cisco ASR 9000 Series Router module in Cisco ASR 9000 Series Aggregation
Services Router System Management Configuration Guide for more information on advanced IP licencing.
The following error message appears if the appropriate licence is not enabled:
RP/0/RSP0/CPU0:router#LC/0/0/CPU0:Dec 15 17:57:53.653 : rsi_agent[247]:
%LICENSE-ASR9K_LICENSE-2-INFRA_VRF_NEEDED : 5 VRF(s) are configured without license
A9K-iVRF-LIC in violation of the Software Right To Use Agreement.
This feature may be disabled by the system without the appropriate license.
Contact Cisco to purchase the license immediately to avoid potential service interruption.
Note An AIP license is not required for configuring L2VPN services.

Purpose
Soft reconfiguration enables the software to store the incoming updates
before apply policy if route refresh is not supported by the peer
(otherwise a copy of the update is not stored). The always keyword
forces the software to store a copy even when route refresh is
supported by the peer.
