Hi There,
I am stuck with a weird issue related to vrf on a qinq layer3 interface.
I have a requirement where ASR1000 router interface connecting to the service provider. SP forwards the traffic in QinQ (dual-tagging). I want the interface within a dedicated VRF. The communication between the client and my device stops working when I configure the VRF with "encapsulation dot1Q xxx second-tag any" (added interface IPs after putting the VRF because it removed the IP address.). It works fine If I specify the second-tag "encapsulation dot1Q xxx second-tag 2".
Everything works fine without VRF.
Setup:
My Device: ASR1000
Client: Windows PC
Diagram:
ASR <---> SP <---> Client
Working Interface Config:
interface TenGigabitEthernet0/1/0.200
encapsulation dot1Q 200 second-dot1q 2
ip vrf forwarding VL200
ip address 192.168.0.1 255.255.255.0
Not Working:
interface TenGigabitEthernet0/1/0.200
encapsulation dot1Q 200 second-dot1q any
ip vrf forwarding VL200
ip address 192.168.0.1 255.255.255.0
IOS:
Cisco IOS XE Software, Version 03.16.09.S - Extended Support Release
Cisco IOS Software, ASR1000 Software (X86_64_LINUX_IOSD-ADVIPSERVICESK9-M), Version 15.5(3)S9, RELEASE SOFTWARE (fc3)
I would appreciate the help.
