A part of learning 메이저사이트 for CCNA exam good results is maintaining each one of these new instructions straight in your head! And let’s experience it, There are plenty of commands you need to know to be able to move the CCNA Examination and make that certification. In this article’s an assessment of some essential length vector and static routing commands you have to know, in addition to their suitable utilization and console output.
Bandwidth
IGRP will make a default assumption that any Serial interface working IGRP is linked 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, utilize the bandwidth command over the serial interface in dilemma. Note this command won't in fact have an impact on the bandwidth accessible to the interface; it basically modifications IGRPs assumption with the bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Distinct ip route *
This command clears your routing desk of all non-static and non-connected routes. Within a lab environment, its pretty handy because it forces your routers operating routing protocols to send out and ask for updates, rather then expecting the frequently scheduled updates.
R2#very clear ip route *
Debug ip igrp occasions
Debug ip igrp gatherings allows you to see IGRP updates currently being sent and requested. Below, the debug is operate then the routing table is cleared. The router promptly broadcasts update requests by using the IGRP-enabled interfaces.
R2#debug ip igrp function
IGRP event 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-Charge load-sharing Along with the variance command, youve acquired to be aware of the metric with the considerably less-attractive routes. EIGRP keeps these in its topology desk; IGRP has no this kind of table.
To obtain the metrics of routes not in the routing table, operate debug ip igrp transactions. To power IGRP updates, the routing table down below was cleared with obvious ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: obtained 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 is now three
06:05:33: IGRP: sending update to 255.255.255.255 through BRI0 (172.12.twelve.2)
06:05:33: network one.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 by using Serial0.123 (172.12.123.two) – suppressing null update
06:05:34: IGRP: acquired update from 172.twelve.twelve.one 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
6:14:53: RIP: obtained v2 update from 172.23.23.3 on Ethernet0
six:14:fifty three: 1.0.0.0/8 via 0.0.0.0 in 16 hops (inaccessible)
6:14:fifty three: 1.one.one.one/32 by way of 0.0.0.0 in two hops
6:14:fifty three: 172.12.0.0/16 by means of 0.0.0.0 in 16 hops (inaccessible)
six:fourteen:53: 172.12.12.2/32 through 0.0.0.0 in two hops
six:fourteen:53: 172.12.thirteen.0/thirty by means of 0.0.0.0 in one hops
six:14:53: 172.12.123.0/24 via 0.0.0.0 in 1 hops
six:14: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 complications, RIP authentication problems, also to view the routing update contents. Very clear ip route * was operate to crystal clear the routing desk also to force a RIP update.
Ip route
R2(config)#ip route 1.one.1.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 path to a supplied desired destination IP handle, make use of the ip route command. The desired destination is accompanied by a subnet mask, and that could be followed by possibly the next-hop IP deal with or perhaps the exit interface to 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.twelve.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 number for the first 0.0.0.0″, because the second list of zeroes is the subnet mask. Consequently any spot will match this route assertion.
That’s an excellent review to start out with! I’ll be http://edition.cnn.com/search/?text=토토사이트 back tomorrow with Component II of this CCNA exam command review!
