In researching for your personal CCNA exam and planning to generate this precious certification, you may be tempted to spend very little time finding out static routing and head suitable for the more interesting dynamic routing protocols like RIP, EIGRP, and OSPF. That is an easy to understand miscalculation, but nonetheless a error. Static routing will not be challenging, but it’s an essential matter to the CCNA Examination and also a beneficial ability for actual-environment networking.
To develop static routes on a Cisco router, you employ the ip route command accompanied by the place community, community mask, and either the subsequent-hop IP tackle or even the area exit interface. It’s essential to keep that last part in your mind – you’re both configuring the IP deal with with the downstream router, or perhaps the interface about the regional router that can serve as the exit interface.
Permit’s say your local router features a serial0 interface with an IP handle of 200.one.one.one/thirty, plus the downstream router that would be the upcoming hop will acquire packets on its serial1 interface having an IP tackle of 200.one.1.2/30. The static route might be for packets destined for your 172.ten.1.0 community. Possibly of the following ip route statements might be right.
R1(config)#ip route 172.10.1.0 255.255.255.0 200.1.1.two (following-hop IP address)
OR
R1(config)#ip route 172.ten.1.0 255.255.255.0 serial0 ( community exit interface)
You can also publish a static route that matches only one location. It is a host route, and it has 255.255.255.255 for any mask. If the above static routes should really only be used to send packets to 172.10.1.1., the subsequent instructions would do The task.
R1(config)#ip route 172.ten.one.one 255.255.255.255 200.1.one.two (subsequent-hop IP tackle)
R1(config)#ip route 172.10.one.1 255.255.255.255 serial0 ( nearby exit interface)
Ultimately, a default static route serves being a gateway of http://edition.cnn.com/search/?text=토토사이트 past resort. If there are no matches to get 먹튀검증 a desired destination inside the routing desk, the default route are going to be employed. Default routes use all zeroes for both of those the place and mask, and again a subsequent-hop IP handle or community exit interface can be utilized.
R1(config)#ip route 0.0.0.0 0.0.0.0 200.one.one.2 (next-hop IP tackle)
R1(config)#ip route 0.0.0.0 0.0.0.0 serial0 ( neighborhood exit interface)
IP route statements seem uncomplicated more than enough, but the main points concerning the following-hop IP tackle, the area exit interface, default static routes, plus the syntax with the command are essential for achievement on CCNA Test working day and in the real world.
