MPLS VPN Workbook Volume I
I was doing MPLS VPN Work book Volume I. after the initial setup of IP addresses and Subinterfaces associated to different VRFs, in the first question, I could not ping from SW1, "SW1#ping vrf VPN_B 172.16.7.7 source loopback 102" and also I coould not ping VPN_B from R6 with this command " R6#ping vrf VPN_B 188.8.131.52". After furthur troubleshooting, I found out "Vlan 76" associated to "VPN_B" is showing down,down. I tried to delete vlan 76 and recreate it as the solution guide says "Interface VLan 76, IP VRF Forwarding VPN_B, IP address 184.108.40.206 255.255.255.0" but VLan 76 stays "down, down".
Towards the end of that configuration in solution guide, it also says "SW1, Sw2, SW3, SW4 : Vlan 76". I dont know if it means to create VLan 76 in all the switches but the question does not says that. I have just created Vlan 76 on SW1 and stayed Down, Down and I could not solve it. Could you please advice if I am missing anything.
