Hi,
I have been trying to configure the OSPF Virtual-link but even after configuring it in the CISCO packet tracer Version 7.0 somehow or other my virtual-link is not getting activated.
Moreover it is even not showing when i am running "SHOW IPV6 OSPF VIRTUAL-LINK".
I am pasting here my router configuration. Can anyone please suggest me what is wrong,why it is not getting activated and it is not even showing?
Please help.......
