Thanks for the tip, but the MTU does not seem to be an issue. I can ping end2end with an IP packet size of 1492...

7200a#ping vrf vpn-customer 
Protocol [ip]: 
Target IP address: Y.206
Repeat count [5]: 
Datagram size [100]: 1496
Timeout in seconds [2]: 
Extended commands [n]: y
Source address or interface: 
Type of service [0]: 
Set DF bit in IP header? [no]: y
Validate reply data? [no]: 
Data pattern [0xABCD]: 
Loose, Strict, Record, Timestamp, Verbose[none]: 
Sweep range of sizes [n]: 
Type escape sequence to abort.
Sending 5, 1496-byte ICMP Echos to Y.206, timeout is 2 seconds:
Packet sent with the DF bit set
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 292/292/292 ms

Also the BGP session is rock-solid.
