[c-nsp] mystery pseudowire interfaces?

[Mike]

Hi,

     I have a metro-ethernet connection between two sites - an asr920 
and an me3600x and am running mpls over it. I have just noticed some 
mystery pseudowire interfaces that have shown up and I strongly think 
it's my metro-e provider leaking data into my circuit. Is this possible? 
Some examples:


pseudowire100012 is up
     MTU 1500 bytes, BW 10000000 Kbit
     Encapsulation l2tpv2
     Peer IP 107.118.108.50, VC ID 1634955825
     RX
       0 packets 0 bytes 0 drops
     TX
       0 packets 0 bytes 0 drops


pseudowire100013 is up
     MTU 1500 bytes, BW 10000000 Kbit
     Encapsulation unknown
     Peer IP 104.100.115.108, VC ID 1969973601
     RX
       0 packets 0 bytes 0 drops
     TX
       0 packets 0 bytes 0 drops
pseudowire100016 is up
     MTU 1500 bytes, BW 10000000 Kbit
     Encapsulation unknown
     Peer IP 48.109.103.109, VC ID 1986802480
     RX
       0 packets 0 bytes 0 drops
     TX
       0 packets 0 bytes 0 drops
pseudowire100023 is up
     MTU 1500 bytes, BW 10000000 Kbit
     Encapsulation unknown
     Peer IP 98.52.48.49, VC ID 2003399541
     RX
       0 packets 0 bytes 0 drops
     TX
       0 packets 0 bytes 0 drops

None of these IPs are me - I have only rfc1918 addresses in my mpls 
network. How is it possible these have been created? I don't understand 
the mechanisam. There are no log entries...
