Well, you don't really have to change the MTU - you'd rather ask the telco why you can't ping with large packets. Normally you should get something like this: Router#ping 172.20.2.14 size 1500 df-bit Type escape sequence to abort. Sending 5, 1500-byte ICMP Echos to 172.20.2.14, timeout is 2 seconds: Packet sent with the DF bit set !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 4/6/12 ms Router#ping 172.20.2.14 size 1501 df-bit Type escape sequence to abort. Sending 5, 1501-byte ICMP Echos to 172.20.2.14, timeout is 2 seconds: Packet sent with the DF bit set ..... Success rate is 0 percent (0/5) If the limit is not 1500, then something is wrong with the circuit.
