A part of finding out for CCNA Examination results is holding all these new commands straight with your head! And Permit’s facial area it, there are a lot of instructions you have to know as a way to pass the CCNA Test and earn that certification. In this article’s an evaluation of some essential length vector and static routing instructions you have to know, as well as their appropriate use and console output.
Bandwidth
IGRP helps make a default assumption that any Serial interface working IGRP is connected to a T1 line, which operates at 1544 KBPS. With equivalent-Value load-balancing enabled by default, this may be an undesirable assumption.
To change IGRPs assumption, make use of the bandwidth command on the serial interface in problem. Notice this command isn't going to basically have an impact on the bandwidth available to the interface; it just variations IGRPs assumption of the bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Crystal clear ip route *
This command clears your routing table of all non-static and non-connected routes. In 메이저사이트 a very lab natural environment, its very handy since it forces your routers working routing protocols to mail and request updates, as opposed to looking ahead to the on a regular basis scheduled updates.
R2#clear ip route *
Debug ip igrp occasions
Debug ip igrp situations enables you to see IGRP updates getting sent and requested. Listed here, the debug is operate and afterwards the routing table is cleared. The router right away broadcasts update requests by using the IGRP-enabled interfaces.
R2#debug ip igrp celebration
IGRP party debugging is on
06:02:51: IGRP: broadcasting ask for on BRI0
06:02:fifty one: IGRP: broadcasting request on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-Price tag load-sharing Along with the variance command, youve received to understand the metric of your fewer-fascinating routes. EIGRP keeps these in its topology table; IGRP has no this sort of desk.
To find the metrics of routes not inside the routing desk, operate debug ip igrp transactions. To power IGRP updates, the routing desk down below was cleared with apparent ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: received update from 172.twelve.123.one on Serial0.123
06:05:33: subnet 172.12.123.0, metric 10476 (neighbor 8476)
06:05:33: network 1.0.0.0, metric 8976 (neighbor 501)
06:05:33: IGRP: edition is now 3
06:05:33: IGRP: sending update to 255.255.255.255 through BRI0 (172.12.12.2)
06:05:33: network one.0.0.0, https://en.wikipedia.org/wiki/?search=토토사이트 metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 via Serial0.123 (172.12.123.two) – suppressing null update
06:05:34: IGRP: been given update from 172.twelve.12.one on BRI0
06:05:34: subnet 172.12.13.0, metric 160250 (neighbor 8476)
06:05:34: community 1.0.0.0, metric 158750 (neighbor 501)
Debug ip rip
R2#debug ip rip
IP protocol debugging is on
six:14:fifty three: RIP: received v2 update from 172.23.23.3 on Ethernet0
6:14:fifty three: one.0.0.0/eight by way of 0.0.0.0 in 16 hops (inaccessible)
6:fourteen:fifty three: one.1.one.one/32 via 0.0.0.0 in 2 hops
six:14:fifty three: 172.twelve.0.0/sixteen by means of 0.0.0.0 in sixteen hops (inaccessible)
six:14:fifty three: 172.12.12.two/32 through 0.0.0.0 in 2 hops
six:14:53: 172.12.13.0/thirty by way of 0.0.0.0 in 1 hops
six:fourteen:fifty three: 172.12.123.0/24 by way of 0.0.0.0 in one hops
six:14:53: 172.23.0.0/sixteen via 0.0.0.0 in 16 hops (inaccessible)
Operate debug ip rip to troubleshoot routing update issues, RIP authentication problems, and also to watch the routing update contents. Very clear ip route * was run to obvious the routing desk also to force a RIP update.
Ip route
R2(config)#ip route 1.1.1.1 255.255.255.255 172.12.123.one
OR
R2(config)#ip route one.one.one.1 255.255.255.255 serial0
To configure a static route to a presented location IP address, make use of the ip route command. The vacation spot is accompanied by a subnet mask, and that could be accompanied by possibly the following-hop IP tackle or even the exit interface to the nearby router.
Ip route 0.0.0.0 0.0.0.0
R2(config)#ip route 0.0.0.0 0.0.0.0 172.12.123.one
R2(config)#ip route 0.0.0.0 0.0.0.0 ethernet0
To configure a default static route, use both of both of these instructions.
You might have any amount for the first 0.0.0.0″, considering that the second list of zeroes is the subnet mask. Consequently any spot will match this route assertion.
That’s a fantastic review to start with! I’ll be again tomorrow with Element II of the CCNA Test command evaluation!
