R2#ping 10.10.10.1



Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.10.10.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/2 ms





In this blog we will start the basic configuration of EIGRP protocol using two routers.firstly We have to assign the IP addressing for the interfaces and after that we will configure the EIGRP on both routers.Continue with configuration dialog?
