Пинг к маршр 1 и маршр 2

router4#ping 175.10.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 175.10.1.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

router4#ping 160.10.1.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 160.10.1.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

Так как команды пинг выполнились успешно, значит , что IGRP сконфигурированы правильно на всех маршрутизаторах.
