Step 5
Verify that the prefix of the remote CE router (CE1) is in the MPLS forwarding table, and that it has an 
outgoing interface.
Router# show mpls forwarding-table vrf <PE-vrf-name> aa.aa.aa.aa
Local  Outgoing    Prefix            Bytes tag  Outgoing   Next Hop    
tag    tag or VC   or Tunnel Id      switched   interface              
None   2/35        aa.aa.aa.aa/32    0          AT5/0.1    point2point  
Router# show mpls forwarding-table vrf <PE-vrf-name> aa.aa.aa.aa detail 
Local  Outgoing    Prefix            Bytes tag  Outgoing   Next Hop    
tag    tag or VC   or Tunnel Id      switched   interface              
None   2/35        aa.aa.aa.aa/32    0          AT5/0.1    point2point  
        MAC/Encaps=4/12, MTU=4466, Tag Stack{2/35(vcd=6) 23}
        00068847 0000600000017000
        No output feature configured
Step 6
Verify that the prefix of the remote CE router (CE1) is in the CEF table.
Router# show ip cef vrf <PE-vrf-name> aa.aa.aa.aa
aa.aa.aa.aa/32, version 10, cached adjacency to ATM5/0.1
0 packets, 0 bytes
  tag information set
    local tag: VPN route head
    fast tag rewrite with AT5/0.1, point2point, tags imposed {2/35(vcd=6) 23}
  via bb.bb.bb.bb, 0 dependencies, recursive
    next hop gg.gg.gg.gg, ATM5/0.1 via bb.bb.bb.bb/32
    valid cached adjacency
    tag rewrite with AT5/0.1, point2point, tags imposed {2/35(vcd=6) 23}
Router# show ip cef vrf <PE-vrf-name> aa.aa.aa.aa detail 
aa.aa.aa.aa/32, version 10, cached adjacency to ATM5/0.1
0 packets, 0 bytes
  tag information set
    local tag: VPN route head
    fast tag rewrite with AT5/0.1, point2point, tags imposed {2/35(vcd=6) 23}
  via bb.bb.bb.bb, 0 dependencies, recursive
    next hop gg.gg.gg.gg, ATM5/0.1 via bb.bb.bb.bb/32
    valid cached adjacency
    tag rewrite with AT5/0.1, point2point, tags imposed {2/35(vcd=6) 23}
Step 7
Verify that the prefix of the local PE router (PE2) is in the CEF table. 
Router# show ip cef hh.hh.hh.hh
hh.hh.hh.hh/32, version 9, connected, receive
  tag information set
    local tag: implicit-null
Router# show ip cef hh.hh.hh.hh detail 
hh.hh.hh.hh/32, version 9, connected, receive
  tag information set
    local tag: implicit-null
