Step 2
Verify that the prefix of the local CE router (CE2) is in the MPLS forwarding table, and is untagged.
Router# show mpls forwarding-table vrf <PE-vrf-name> jj.jj.jj.jj
Local Outgoing Prefix Bytes tag Outgoing Next Hop
tag tag or VC or Tunnel Id switched interface
32 Untagged jj.jj.jj.jj/32[V] 0 Et3/6 tt.0.0.2
Router# show mpls forwarding-table vrf <PE-vrf-name> jj.jj.jj.jj detail
Local Outgoing Prefix Bytes tag Outgoing Next Hop
tag tag or VC or Tunnel Id switched interface
32 Untagged jj.jj.jj.jj/32[V] 0 Et3/6 tt.0.0.2
MAC/Encaps=0/0, MTU=1504, Tag Stack{}
VPN route: vpn2
No output feature configured
Per-packet load-sharing, slots: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Step 3
Verify that the prefix of the remote PE router (PE1) is in the CEF table.
Router# show ip cef bb.bb.bb.bb
bb.bb.bb.bb/32, version 19, cached adjacency to ATM5/0.1
0 packets, 0 bytes
tag information set
local tag: 20
fast tag rewrite with AT5/0.1, point2point, tags imposed {2/35(vcd=6)}
via gg.gg.gg.gg, ATM5/0.1, 2 dependencies
next hop gg.gg.gg.gg, ATM5/0.1
unresolved
valid cached adjacency
tag rewrite with AT5/0.1, point2point, tags imposed {2/35(vcd=6)}
Router# show ip cef bb.bb.bb.bb detail
bb.bb.bb.bb/32, version 19, cached adjacency to ATM5/0.1
0 packets, 0 bytes
tag information set
local tag: 20
fast tag rewrite with AT5/0.1, point2point, tags imposed {2/35(vcd=6)}
via gg.gg.gg.gg, ATM5/0.1, 2 dependencies
next hop gg.gg.gg.gg, ATM5/0.1
unresolved
valid cached adjacency
tag rewrite with AT5/0.1, point2point, tags imposed {2/35(vcd=6)}
Step 4
Verify that the loopback address of the remote CE router (CE1) is in the routing table.
Router# show ip route vrf <PE-vrf-name> aa.aa.aa.aa
Routing entry for aa.aa.aa.aa/32
Known via "bgp 200", distance 200, metric 0
Tag 300, type internal
