Hi, I am watching the Video and pratise it in GNS3, in this MPLS L3 VPN Configuration lab, R2, R4, R5 and R6 are running OSPF type Point-to-Multipoint, it generates host route and send it to neighbor, when further configured MPLS, I see something wrong here. For example, R2 has serial interface IP 100.100.100.2/24 configured, in OSPF world, R6 receives a host route 100.100.100.2/32, nothing is wrong untill MPLS is enabled. R6 assigns a lable to host route 100.100.100.2/32 and advertise it. But since R2 doesn't have this host route in its routing table, it only has 100.100.100.2/24 as Connected route, so R6 will not recevie lable for 100.100.100.2/32 from R2, in the LFIB, the Outgoing Lable is untagged: R6#sh mpls forwarding-table Local Outgoing Prefix Bytes tag Outgoing Next Hop tag tag or VC or Tunnel Id switched interface 16 Untagged 100.100.100.5/32 0 Se1/0 100.100.100.5 17 Untagged 100.100.100.2/32 0 Se1/0 100.100.100.2 18 Pop tag 5.5.5.5/32 0 Se1/0 100.100.100.5 19 Pop tag 2.2.2.2/32 0 Se1/0 100.100.100.2 20 Untagged 100.100.100.4/32 0 Se1/0 100.100.100.4 21 Pop tag 4.4.4.4/32 0 Se1/0 100.100.100.4 R6# same thing for all other host routes from spoke routers. I think this will cause problem for L3 VPN. Any ideal? Thanks Jason
