Element of studying for CCNA exam accomplishment is keeping each one of these new commands straight as part of your head! And Enable’s encounter it, there are a lot of commands you have to know so as to go the CCNA Examination and earn that certification. In this article’s an evaluation http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/토토사이트 of some extremely important distance vector and static routing commands you need to know, in conjunction with their correct use and console output.
Bandwidth
IGRP helps make a default assumption that any Serial interface jogging IGRP is linked to a T1 line, which operates at 1544 KBPS. With equivalent-Price tag load-balancing enabled by default, this may be an undesirable assumption.
To change IGRPs assumption, make use of the bandwidth command over the serial interface in question. Observe this command would not basically have an affect on the bandwidth available to the interface; it merely modifications IGRPs assumption of your 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. In a lab environment, its very helpful as it forces your routers managing routing protocols to send and request updates, instead of awaiting the consistently scheduled updates.
R2#very clear ip route *
Debug ip igrp situations
Debug ip igrp activities enables you to see IGRP updates becoming sent and asked for. Below, the debug is run then the routing desk is cleared. The router immediately broadcasts update requests by means of the IGRP-enabled interfaces.
R2#debug ip igrp celebration
IGRP function 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 With all the variance command, youve bought to learn the metric in the a lot less-attractive routes. EIGRP keeps these in its topology desk; IGRP has no this sort of table.
To have the metrics of routes not during the routing table, operate debug ip igrp transactions. To power IGRP updates, the routing table under was cleared with 먹튀검증업체 clear ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: been given update from 172.12.123.1 on Serial0.123
06:05:33: subnet 172.12.123.0, 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 (172.12.12.two)
06:05:33: community 1.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 by way of Serial0.123 (172.twelve.123.two) – suppressing null update
06:05:34: IGRP: acquired update from 172.12.12.1 on BRI0
06:05:34: subnet 172.twelve.13.0, metric 160250 (neighbor 8476)
06:05:34: network one.0.0.0, metric 158750 (neighbor 501)
Debug ip rip
R2#debug ip rip
IP protocol debugging is on
6:14:fifty three: RIP: gained v2 update from 172.23.23.3 on Ethernet0
6:14:53: one.0.0.0/eight through 0.0.0.0 in 16 hops (inaccessible)
6:14:53: one.1.1.1/32 by way of 0.0.0.0 in two hops
six:fourteen:53: 172.12.0.0/sixteen through 0.0.0.0 in 16 hops (inaccessible)
six:fourteen:53: 172.12.twelve.two/32 by using 0.0.0.0 in 2 hops
6:fourteen:53: 172.twelve.13.0/30 by way of 0.0.0.0 in 1 hops
six:14:53: 172.12.123.0/24 by means of 0.0.0.0 in one hops
six:fourteen:fifty three: 172.23.0.0/16 via 0.0.0.0 in 16 hops (inaccessible)
Run debug ip rip to troubleshoot routing update challenges, RIP authentication difficulties, and to perspective the routing update contents. Obvious ip route * was operate to clear the routing desk and to power a RIP update.
Ip route
R2(config)#ip route one.one.1.one 255.255.255.255 172.twelve.123.one
OR
R2(config)#ip route one.1.one.1 255.255.255.255 serial0
To configure a static path to a given destination IP handle, use the ip route command. The spot is followed by a subnet mask, and that could be accompanied by both another-hop IP tackle or even the exit interface over the neighborhood 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 possibly of these two commands.
You could have any variety for the 1st 0.0.0.0″, since the next list of zeroes could be the subnet mask. Therefore any location will match this route assertion.
That’s a good evaluate to start with! I’ll be again tomorrow with Portion II of the CCNA Examination command evaluation!
