Understanding the Purpose of Routing<\/h2>\n

Stop broadcasts
\nAllow packets to move from one network to another
\nBy default, routers only know what they are plugged into<\/p>\n

How Static Routing Can Help<\/h2>\n

Manually tell routers what networks they can reach<\/p>\n

r2(config)#ip route 192.168.33.0 255.255.255.0 192.168.22.2<\/pre>\n
192.168.33.0 = Destination Network
\n255.255.255.0 = Destination Subnet Mask
\n192.168.22.2 = Next Hop IP Address<\/p>\n
In order to return the traffic, you must also let the connecting router know how to get back!<\/p>\n
r3(config)#ip route 192.168.11.0 255.255.25.0 192.168.22.1<\/pre>\n
 <\/p>\n
Configure a default route<\/h3>\n
Default routes are used for anything that is unknown to the router<\/p>\n
r2(config)#ip route 0.0.0.0 0.0.0.0 192.168.11.1<\/pre>\n
0.0.0.0 = Any unknown IP address
\n0.0.0.0 = Any subnet mask
\n192.168.11.1 = IP Address of next hop for router to access.<\/p>\n
Configure DNS Name Servers<\/h3>\n
r1(config)#ip name-server IP.ADD.RE.SS<\/pre>\n
 <\/p>\n
Putting it all together<\/h2>\n
Router #3<\/h3>\n
