A person stage of confusion for some CCNA and CCNP candidates is the variation in between configuring a static default route and using the Cisco routing command ip default-network. At initially glance, they seem to do the very same point. Both configure a vacation destination to which day trading packets should be routed if there is no much more certain route in the routing table. The important distinction between these two options is that configuring a static default route only defines a default route for the router you are configuring it on, although ip default-network will propagate the route by means of its routing protocol. Let's study the routing tables of a hub-and-spoke network using the ip default-network command. R1 is the hub and R2 and R3 are the spokes. They are immediately related via the network 172.12.123. /24, and every single has a loopback with a 32-bit mask that are numbered in accordance to the router quantity (one.1.one.1, etcetera.) RIP is operating on all a few routers and the loopbacks are advertised. R1 has yet another serial interface with the IP tackle ten.1.one.1 /24, and this network has been flagged as a default network with the command ip default-network ten... . It is not being marketed by RIP. The routing protocol will then promote this route. With RIP, the default network is online currency forex advertised as ... . (With IGRP, it appears as the network amount, but is marked as an IGRP External route. ) This route has been specified a applicant default route on R1, as we see with the asterisk following to the 10... /24 daytrading6636.com network (code table taken out for brevity) R1show ip route Gateway of final resort is not set one.../32 is subnetted, 1 subnets C one.1.1.one is straight connected, Loopback0 R two.../8 a hundred and twenty/1 through 172.twelve.123.2, 000011, Serial0 R daytrading6636.com three.../eight one hundred twenty/1 by means of 172.twelve.123.three, 000011, Serial0 172.12../16 is variably subnetted, two subnets, 2 masks C 172.12.21./30 is immediately related, BRI0 Do 172.12.123./24 is straight linked, Serial0 * 10.../24 is subnetted, one subnets C forex trading 10.1.one. is immediately related, Serial1 On R2 and R3, a default RIP route is now seen (code tables again deleted) R2show ip route Gateway of last resort is 172.twelve.123.one to network ...

But if you want only the regional router to have the default route, a static IP route is the way to go.
