Element of studying for CCNA Test accomplishment is maintaining these new commands straight as part of your head! And let’s deal with it, There are many of commands you have to know as a way to pass the CCNA exam and gain that certification. Below’s an assessment of some crucial distance vector and static routing instructions you have to know, coupled with their appropriate utilization and console output.
Bandwidth
IGRP makes a default assumption that any Serial interface functioning IGRP is linked to a T1 line, which operates at 1544 KBPS. With equivalent-Expense load-balancing enabled by default, This can be an undesirable assumption.
To change IGRPs assumption, use the bandwidth command around the serial interface in query. Take note this command would not truly have an effect on the bandwidth accessible to the interface; it merely adjustments IGRPs assumption of the bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Apparent ip route *
This command clears your routing desk of all non-static and non-linked routes. Inside of a lab surroundings, its extremely helpful since http://edition.cnn.com/search/?text=토토사이트 it forces your routers operating routing protocols to send and request updates, rather than expecting the consistently scheduled updates.
R2#clear ip route *
Debug ip igrp situations
Debug ip igrp occasions means that you can see IGRP updates currently being sent and asked for. In this article, the debug is run after which you can the routing table is cleared. The router promptly broadcasts update requests via the IGRP-enabled interfaces.
R2#debug ip igrp function
IGRP party debugging is on
06:02:51: IGRP: broadcasting request on BRI0
06:02:fifty one: IGRP: broadcasting request on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-Value load-sharing Using 메이저사이트 the variance command, youve got to understand the metric of the significantly less-desirable routes. EIGRP retains these in its topology desk; IGRP has no this kind of desk.
To get the metrics of routes not within the routing table, operate debug ip igrp transactions. To drive IGRP updates, the routing desk below was cleared with clear ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: acquired update from 172.12.123.one on Serial0.123
06:05:33: subnet 172.twelve.123.0, metric 10476 (neighbor 8476)
06:05:33: community one.0.0.0, metric 8976 (neighbor 501)
06:05:33: IGRP: edition has become 3
06:05:33: IGRP: sending update to 255.255.255.255 by way of BRI0 (172.twelve.twelve.2)
06:05:33: network 1.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 by using Serial0.123 (172.twelve.123.two) – suppressing null update
06:05:34: IGRP: gained update from 172.12.12.1 on BRI0
06:05:34: subnet 172.12.thirteen.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:14:53: RIP: received v2 update from 172.23.23.three on Ethernet0
6:14:53: 1.0.0.0/eight via 0.0.0.0 in 16 hops (inaccessible)
6:14:fifty three: one.1.one.1/32 by way of 0.0.0.0 in two hops
six:14:fifty three: 172.12.0.0/sixteen by using 0.0.0.0 in sixteen hops (inaccessible)
six:14:fifty three: 172.twelve.12.two/32 via 0.0.0.0 in 2 hops
6:14:fifty three: 172.12.thirteen.0/30 by using 0.0.0.0 in 1 hops
six:14:fifty three: 172.12.123.0/24 through 0.0.0.0 in one hops
6:fourteen:53: 172.23.0.0/16 by way of 0.0.0.0 in sixteen hops (inaccessible)
Run debug ip rip to troubleshoot routing update challenges, RIP authentication challenges, also to check out the routing update contents. Distinct ip route * was run to clear the routing table and to drive a RIP update.
Ip route
R2(config)#ip route one.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 supplied desired destination IP deal with, make use of the ip route command. The location is accompanied by a subnet mask, and which might be accompanied by possibly the next-hop IP address or even the exit interface on the community router.
Ip route 0.0.0.0 0.0.0.0
R2(config)#ip route 0.0.0.0 0.0.0.0 172.12.123.1
R2(config)#ip route 0.0.0.0 0.0.0.0 ethernet0
To configure a default static route, use either of these two instructions.
You might have any range for the primary 0.0.0.0″, considering that the 2nd list of zeroes is the subnet mask. Consequently any location will match this route assertion.
That’s a great critique to begin with! I’ll be back again tomorrow with Part II of this CCNA Test command evaluation!
