Validation
1. Verify ping from PE1 to PE2
PE1#ping 11.1.1.8
Press CTRL+C to exit
PING 11.1.1.8 (11.1.1.8) 56(84) bytes of data.
64 bytes from 11.1.1.8: icmp_seq=1 ttl=63 time=0.683 ms

64 bytes from 11.1.1.8: icmp_seq=3 ttl=63 time=0.594 ms
2. Verify mpls l3vpn ping from PE1
PE1#ping mpls l3vpn vrf100 101.1.1.0/24
Sending 5 MPLS Echos to 101.1.1.0, timeout is 5 seconds
Codes:
'!' - Success, 'Q' - request not sent, '.' - timeout,
'x' - Retcode 0, 'M' - Malformed Request, 'm' - Errored TLV,
'N' - LBL Mapping Err, 'D' - DS Mismatch,
'U' - Unknown Interface, 'R' - Transit (LBL Switched),
'B' - IP Forwarded, 'F' No FEC Found, 'f' - FEC Mismatch,
'P' - Protocol Error, 'X' - Unknown code,
'Z' - Reverse FEC Validation Failed

3. Verify the TWAMP statistics on all the configured interfaces on PE1
In the below verification command, packets sent and received showing as equal. So all the TWAMP packets received reply for all the sent packets for the delay measurement. Showing all the Round Trip Delay and Reverse Delay timers.
PE1#sh twamp-statistics
