A part of finding out for CCNA Test achievements is maintaining each one of these new commands straight in your head! And Permit’s confront it, There are tons of commands you need to know as a way to go the CCNA Test and earn that certification. Below’s an evaluation of some important length vector and static routing instructions you need to know, in conjunction with their appropriate use and console output.
Bandwidth
IGRP can make a default assumption that any Serial interface jogging IGRP is connected to a T1 line, which runs at 1544 KBPS. With equivalent-Charge 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 dilemma. Observe this command doesn't essentially have an affect on the bandwidth available to the interface; it basically changes 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 desk of all non-static and non-connected routes. Within a lab environment, its incredibly handy because it forces your routers managing routing protocols to deliver and request updates, as an alternative to awaiting the on a regular basis scheduled updates.
R2#obvious ip route *
Debug ip igrp events
Debug ip igrp events helps you to see IGRP updates remaining sent and requested. Below, the debug is run after which you can the routing table is cleared. The router straight away broadcasts update requests by using the IGRP-enabled interfaces.
R2#debug ip igrp celebration
IGRP celebration debugging is on
06:02:fifty one: IGRP: broadcasting request on BRI0
06:02:fifty one: IGRP: broadcasting request on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-Price tag load-sharing While using the variance command, youve got to grasp the metric of your considerably less-attractive routes. EIGRP keeps these in its topology desk; IGRP has no such table.
To find the metrics of routes not within the routing table, operate debug ip igrp transactions. To pressure IGRP updates, the routing desk underneath was cleared with obvious ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: gained update from 172.twelve.123.one on Serial0.123
06:05:33: subnet 172.twelve.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 three
06:05:33: IGRP: sending update to 255.255.255.255 by way of 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 by way of Serial0.123 (172.twelve.123.2) – suppressing null update
06:05:34: IGRP: received update from 172.12.12.1 on BRI0
06:05:34: subnet 172.12.13.0, metric 160250 (neighbor 8476)
06:05:34: community one.0.0.0, metric 158750 (neighbor 501)
Debug ip rip
R2#debug ip rip
IP protocol debugging is on
6:fourteen:53: RIP: been given v2 update from 172.23.23.3 on Ethernet0
6:14:53: 1.0.0.0/8 via 0.0.0.0 in sixteen hops (inaccessible)
six:fourteen:fifty three: 1.1.one.1/32 by way of 0.0.0.0 in 2 hops
six:14:53: 172.12.0.0/16 through 0.0.0.0 in sixteen hops (inaccessible)
6:fourteen:fifty three: 172.twelve.12.2/32 via 0.0.0.0 in 2 hops
six:fourteen:53: 172.12.thirteen.0/thirty by using 0.0.0.0 in one hops
6:fourteen:fifty three: 172.12.123.0/24 by way of 0.0.0.0 in 1 hops
six:14:fifty three: 172.23.0.0/16 by means of 0.0.0.0 in 16 hops (inaccessible)
Operate debug ip rip to troubleshoot routing update issues, RIP authentication challenges, also to look at the routing update contents. Obvious ip 먹튀검증업체 route * was run to very clear the routing desk and also to pressure a RIP update.
Ip route
R2(config)#ip route 1.one.one.one 255.255.255.255 172.12.123.1
OR
R2(config)#ip route 1.one.1.one 255.255.255.255 serial0
To configure a static route to a specified vacation spot IP tackle, use the ip route command. The location is followed by a subnet http://www.thefreedictionary.com/토토사이트 mask, and which might be followed by possibly the next-hop IP tackle or perhaps the exit interface around 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.one
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 number for the 1st 0.0.0.0″, because the second set of zeroes would be the subnet mask. Which means that any place will match this route statement.
That’s a superb overview to get going with! I’ll be back again tomorrow with Portion II of this CCNA Examination command review!
