Element of studying for CCNA assessment success is keeping all these new instructions straight in-your head! And let's face it, there are always a lot of instructions earn that accreditation and you need to know to be able to pass the CCNA exam. Here is a review of some crucial distance vector and static routing commands you should know, along with their proper use and unit output.

Bandwidth

IGRP makes a default assumption that any Serial screen running IGRP is linked to a line, which runs at 15-44 KBPS. With equal-cost load-balancing enabled by default, this may be an assumption.

To adjust IGRPs assumption, utilize the bandwidth command on the serial interface in question. Remember that this command does NOT actually affect the bandwidth offered to the interface; it only changes IGRPs prediction of the bandwidth.

R2#conf t

R2( config )#int s0

R2( config-if )#bandwidth 5-12

Clear internet protocol address option *

This command clears your routing table of all non-connected and non-static channels. In a lab environment, its very practical because it forces your modems working routing protocols to send and request updates, as opposed to awaiting the regularly scheduled updates.

R2#clear internet protocol address route *

De-bug ip igrp events

Debug internet protocol address igrp activities allows you to see IGRP updates being sent and requested. Here, the debug is run and then your routing dining table is cleared. The router instantly shows update needs via the IGRP-enabled interfaces.

R2#debug internet protocol address igrp function

IGRP event debugging is on

R2#clear ip way *

06:02:51: IGRP: transmission request on BRI0

06:02:51: IGRP: transmission request o-n Serial0.123

Debug internet protocol address igrp transactions

To change IGRP unequal-cost load-sharing with the variance control, youve got to know the metric of the less-desirable channels. EIGRP keeps these in its topology table; IGRP does not have any such dining table.

To acquire the measurements of channels perhaps not in-the routing dining table, run de-bug ip address igrp transactions. The routing dining table below was satisfied with clear ip address route *, to force IGRP changes.

R2#debug internet protocol address igrp transactions

IGRP protocol debugging is o-n

R2#clear ip address route *

06:05:33: IGRP: acquired update from 172.12.123.1 o-n Serial0.123

06:05:33: subnet 172.12.123.0, metric 10476 (friend 8476)

06:05:33: network 1.0.0.0, metric 8976 (neighbor 501)

06:05:33: IGRP: model is currently 3

06:05:33: IGRP: delivering update to 255.255.255.255 via BRI0 (172.12.12.2)

06:05:33: system 1.0.0.0, metric=8976

06:05:33: IGRP: delivering update to 255.255.255.255 via Serial0.123 (172.12.123.2) - controlling null update

O-n BRI0 06:05:34: IGRP: obtained update from 172.12.12.1

06:05:34: subnet 172.12.13.0, full 160250 (friend 8476)

06:05:34: system 1.0.0.0, full 158750 (friend 501)

Debug ip address rip

R2#debug ip address grab

IP protocol debugging is o-n

R2#clear ip address way *

O-n Ethernet0 6:14:53: RIP: received v2 update from 172.23.23.3

6:14:53: 1.0.0.0/8 via 0.0.0.0 in 1-6 trips (unavailable)

6:14:53: 1.1.1.1/32 via 0.0.0.0 in 2 hops

6:14:53: 172.12.0.0/16 via 0.0.0.0 in 16 trips (inaccessible)

6:14:53: 172.12.12.2/32 via 0.0.0.0 in 2 hops

6:14:53: 172.12.13.0/30 via 0.0.0.0 in 1 hops

6:14:53: 172.12.123.0/24 via 0.0.0.0 in 1 hops

6:14:53: 172.23.0.0/16 via 0.0.0.0 in 1-6 hops (unavailable)

Run debug ip rip to troubleshoot routing update problems, RIP verification problems, and to view the routing update items. My brother learned about open in a new browser window by searching the Internet. Clear ip way * was run to force a RIP update and to clear the routing dining table.

Internet protocol address course

R2#conf t

R2( config )#ip course 1.1.1.1 255.255.255.255 172.12.123.1

OR

R2( config )#ip route 1.1.1.1 255.255.255.255 serial0

To configure a static route to a given destination IP address, make use of the ip route command. If you have an opinion about writing, you will likely need to learn about www.newswire.net/newsroom/pr/00082455-perry-belcher-discusses-using-a-client-centric-business-model.html/ . The spot is followed by a subnet mask, and that may be followed by either the next-hop IP or the exit interface to the local router.

Ip course 0.0.0.0 0.0.0.0

R2#conf t

R2( config )#ip path 0.0.0.0 0.0.0.0 172.12.123.1

OR

R2( config )#ip route 0.0.0.0 0.0.0.0 ethernet0

To change a default static route, use both of the two directions.

You might have any number for your first 0.0.0.0', since the second pair of zeroes is the subnet mask. This means that any spot can match this route statement.

That's a good assessment to get started with! I will be straight back tomorrow with Part II of this CCNA assessment order assessment!.
