Kevin,

      Under normal configuration r1 can not ping to r4 also r2 can not ping to r3. Your backbone doesn't know customer (edge) info.
You should ping from r3 to r4. Double check your r1 and r2 configurations.

hi, group
   when i config mpls vpn, r1 and r2 are 3640, as PE; r3 and r4 are 2610, as CE. IOS are 12.1.3T
r3-------------r1--------------r2---------------r4
    ether            atm               ether

r1 could ping r3, and r2 could ping r4, r3 and r4 could see each other routes, but r3 couldn't ping r4
and r1 couldn't ping r4, r2 could not ping r3.
i fould r1 and r2 didn't tag the vpn, this is the show on r1:

r1#sh tag-switching for vrf vpn-lab detail
Local  Outgoing    Prefix            Bytes tag  Outgoing   Next Hop
tag    tag or VC   or Tunnel Id      switched   interface
16     Untagged    136.5.1.0/24[V]   0          Fa0/1      10.1.1.1
        MAC/Encaps=0/0, MTU=1500, Tag Stack{}
        VPN route: vpn-lab
    Per-packet load-sharing
17     Aggregate   10.1.1.0/24[V]    0
        MAC/Encaps=0/0, MTU=0, Tag Stack{}
        VPN route: vpn-lab
    Per-packet load-sharing

any advice are appreciated.


one another question: one PE in a AS through static route connects to another PE in another AS, 
  could it can solve the mpls vpn could not span AS problem ? thanks.

This is same as mpls vpn over multiple AS.


        Regards.
