If we want R1 to forward packets to subnet 2.0.0.0 then we need to configure a static route.īasic Configuration of R2: Router> enable Routing table of R1 shows that subnets 1.0.0.0 and 12.0.0.0 are directly connected and can be pinged but subnet 2.0.0.0 cannot be accessed as it is directly connected to R2 and not to R1. * - candidate default, U - per-user static route, o - ODRĬ 1.0.0.0/8 is directly connected, Loopback0Ĭ 12.0.0.0/8 is directly connected, Serial0/1/0 I - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2Į1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP R1(config-if)# ip address 1.1.1.1 255.0.0.0Ĭhecking Routing Table of router R1: R1#show ip routeĬodes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGPĭ - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area We have explained the functionality of DCE and DTE in more details in how to set clock rate on Cisco router. DCE interface provides the clocking to the routers connected through it. You should note that when connecting two routers through serial cable, the serial interface of one router must be configured as DCE(Data Communication Equipment). We will demonstrate adding static routes with the help of two routers, router R1 and router R2, and three subnets 12.0.0.0, 1.0.0.0 and 2.0.0.0. By adding a static route, a router can be told how to send or forward packets to the subnets that are not directly attached.
