Hi Victor,
After i input the command below, virtual link still down.
I dont kown why, because i think my configuration is already true.. may be
something about ospf type or election DR or BDR?? but i try make R6 serial
is ip ospf priority 0 and R5 still prioirty 1 but still virtual link not
making up..
