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

17 Aggregate 10.1.1.0/24[V] 0
MAC/Encaps=0/0, MTU=0, Tag Stack{}
VPN route: vpn-lab

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.
