Hi , I'm studying for CCNP SP and I use GNS3 for the labs. I'm trying to config a xconnect and the tunnel is up but no connectivity between CEs. I don't know if I'm missing something or GNS3 doesn't work fine
It seems all is working fine :
LDP sessions UP
OSPF OK
MPLS LABELS OK
XCONNECT UP , VC UP
But can't ping from R1 to R2
