VRF Dynamic Route Leaking Configuration: Example
Import Routes from default-VRF to non-default-VRF:
vrf vrf_1
address-family ipv6 unicast
import from default-vrf route-policy rpl_dynamic_route_import
!
end
Import Routes from non-default-VRF to default-VRF
vrf vrf_1
address-family ipv6 unicast
!
end
What to Do Next
These show bgp command output displays information from the dynamic route leaking configuration:
• Use the show bgp prefix command to display the source-RD and the source-VRF for imported paths,
• Use the show bgp imported-routes command to display IPv4 unicast and IPv6 unicast address-families
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.
The following error message appears if the appropriate licence is not enabled:
RP/0/RP0/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.
