Validation
1. Verify ping from CE1 to CE2
PE1#ping 172.16.10.2
Press CTRL+C to exit
PING 172.16.10.2 (172.16.10.2) 56(84) bytes of data.
64 bytes from 172.16.10.2: icmp_seq=1 ttl=64 time=0.776 ms
64 bytes from 172.16.10.2: icmp_seq=2 ttl=64 time=0.553 ms
2. Verify the TWAMP statistics on all the configured interfaces on CE1
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
