    Did you change the next-hop value.

    Paste your config and BGP output here.

    The main problem of this on IOS is next-hop change/update. IOS-XR does automatically but IOS doesn't do this because of bug in IOS.

    Just change Next-hop in PE and CE routers: Example:

    CE

    router bgp 1
     no bgp default ipv4-unicast
     bgp log-neighbor-changes
     neighbor 12.12.12.2 remote-as 100
     !
     address-family ipv4
      no synchronization
      no auto-summary
     exit-address-family
     !
     address-family ipv6
      network 2001::1/128
      neighbor 12.12.12.2 activate
      neighbor 12.12.12.2 allowas-in
      neighbor 12.12.12.2 route-map R2 in
    !

    route-map R2 permit 10
     set ipv6 next-hop 2000:12:12:12::2

    PE:

    router bgp 100
     no bgp default ipv4-unicast
     bgp log-neighbor-changes
     neighbor 4.4.4.4 remote-as 100
     neighbor 4.4.4.4 update-source Loopback0
     neighbor 12.12.12.1 remote-as 1
     !
     address-family ipv4
      no synchronization
      no auto-summary
     exit-address-family
     !
     address-family vpnv4
      neighbor 4.4.4.4 activate
      neighbor 4.4.4.4 send-community extended
     exit-address-family
     !
     address-family vpnv6
      neighbor 4.4.4.4 activate
      neighbor 4.4.4.4 send-community extended
     exit-address-family
     !
     address-family ipv4 vrf A
      no synchronization
     exit-address-family
     !
     address-family ipv6 vrf A
      neighbor 12.12.12.1 remote-as 1
      neighbor 12.12.12.1 activate
      neighbor 12.12.12.1 as-override
      neighbor 12.12.12.1 route-map R1 in
     exit-address-family
    !
    route-map R1 permit 10
     set ipv6 next-hop 2000:12:12:12::1
    !

    CE can ping to another CE now:

    R1#ping 2002::2 so lo0

    Type escape sequence to abort.
    Sending 5, 100-byte ICMP Echos to 2002::2, timeout is 2 seconds:
    Packet sent with a source address of 2001::1
    !!!!!
    Success rate is 100 percent (5/5), round-trip min/avg/max = 76/123/156 ms
    R1#

    No, XR Series automatically updates Next-hop. But in IOS, we should change manually in both CE and PE.
