Element of learning for CCNA Examination achievements is holding every one of these new instructions straight inside your head! And Permit’s confront it, There are tons of commands you need to know in an effort to go the CCNA Examination and get paid that certification. Below’s an assessment of some crucial distance vector and static routing instructions you need to know, along with their good usage and console output.
Bandwidth
IGRP helps make a default assumption that any Serial interface functioning IGRP is linked to a T1 line, which runs at 1544 KBPS. With equivalent-Price tag load-balancing enabled by default, this may be an unwanted assumption.
To change IGRPs assumption, utilize the bandwidth command about the serial interface in issue. Take note that this command would not really affect the bandwidth available to the interface; it basically variations IGRPs assumption from 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 a lab environment, its extremely helpful as it forces your routers running routing protocols to mail and request updates, rather than looking ahead to the regularly scheduled updates.
R2#crystal clear ip route *
Debug ip igrp activities
Debug ip igrp events lets you see IGRP updates staying despatched and asked for. Here, the debug is run and afterwards the routing desk is cleared. The router promptly broadcasts update requests through the IGRP-enabled interfaces.
R2#debug ip igrp function
IGRP event debugging is on
06:02:fifty one: IGRP: broadcasting ask for on BRI0
06:02:51: IGRP: broadcasting ask for on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-Price tag load-sharing Together with the variance command, youve bought to know the metric of the a lot less-fascinating routes. EIGRP keeps these in its topology table; IGRP has no this sort of 토토사이트 desk.
To get the metrics of routes not inside the routing desk, run debug ip igrp transactions. To force 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.twelve.123.0, metric 10476 (neighbor 8476)
06:05:33: community one.0.0.0, metric 8976 (neighbor 501)
06:05:33: IGRP: version is currently three
06:05:33: IGRP: sending update to 255.255.255.255 through BRI0 (172.12.twelve.2)
06:05:33: network 1.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 via Serial0.123 (172.twelve.123.two) – suppressing null update
06:05:34: IGRP: obtained update from 172.12.twelve.1 on BRI0
06:05:34: subnet 172.twelve.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:fifty three: RIP: received v2 update from 172.23.23.3 on Ethernet0
6:fourteen:fifty three: 1.0.0.0/8 by way of 0.0.0.0 in sixteen hops (inaccessible)
6:14:53: 1.one.1.one/32 by using 0.0.0.0 in two hops
six:14:fifty three: 172.twelve.0.0/16 through 0.0.0.0 in sixteen hops (inaccessible)
six:14:53: 172.twelve.12.2/32 by using 0.0.0.0 in two hops
six:fourteen:fifty three: 172.12.thirteen.0/30 via 0.0.0.0 in one hops
six:fourteen:fifty three: 172.twelve.123.0/24 by means of 0.0.0.0 in 1 hops
6:fourteen:fifty three: 172.23.0.0/sixteen by using 0.0.0.0 in sixteen hops (inaccessible)
Operate 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 also to power a RIP update.
Ip route
R2(config)#ip route 1.1.one.one 255.255.255.255 172.12.123.1
OR
R2(config)#ip route 1.1.1.one 255.255.255.255 serial0
To configure a static route to a offered desired destination IP tackle, make use of the ip route command. The vacation spot is accompanied by a subnet mask, and that can be accompanied by either the subsequent-hop IP deal with or the exit interface to the community router.
Ip route 0.0.0.0 0.0.0.0
R2(config)#ip http://edition.cnn.com/search/?text=토토사이트 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 these two commands.
You might have any quantity for the initial 0.0.0.0″, because the next set of zeroes is definitely the subnet mask. Consequently any spot will match this route assertion.
That’s an excellent overview to get rolling with! I’ll be again tomorrow with Element II of the CCNA Examination command overview!
