A part of studying for CCNA exam results is retaining these new commands straight in your head! And Permit’s encounter it, There are tons of instructions you have to know so as to pass the CCNA Test and generate that certification. Below’s a review of some vital distance vector and static routing instructions you have to know, along with their right usage and console output.
IGRP can make a default assumption that any Serial interface managing IGRP is linked to a 토토사이트 T1 line, which operates at 1544 KBPS. With equivalent-Price tag load-balancing enabled by default, This can be an undesirable assumption.
To change IGRPs assumption, utilize the bandwidth command over the serial interface in problem. Be aware that this command does NOT essentially impact the bandwidth accessible to the interface; it merely modifications IGRPs assumption from the bandwidth.
Apparent ip route *
This command clears your routing table of all non-static and non-linked routes. Inside a lab environment, its pretty helpful since it forces your routers working routing protocols to deliver and ask for updates, rather then awaiting the routinely scheduled updates.
R2#very clear ip route *
Debug ip igrp events
Debug ip igrp gatherings means that you can see IGRP updates staying sent and asked for. In this article, the debug is run and afterwards the routing desk is cleared. The router instantly broadcasts update requests by using the IGRP-enabled interfaces.
R2#debug ip igrp celebration
IGRP function debugging is on
06:02:fifty one: IGRP: broadcasting request 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 received to learn the metric on the considerably less-attractive routes. EIGRP retains these in its topology desk; IGRP has no this sort of table.
To find the metrics of routes not from the routing table, run debug ip igrp transactions. To pressure IGRP updates, the routing desk under was cleared with apparent ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: obtained update from 172.twelve.123.one on Serial0.123
06:05:33: subnet 184.108.40.206, metric 10476 (neighbor 8476)
06:05:33: community one.0.0.0, metric 8976 (neighbor 501)
06:05:33: IGRP: version has become 3
06:05:33: IGRP: sending update to 255.255.255.255 by way of BRI0 (172.twelve.twelve.2)
06:05:33: community 220.127.116.11, 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: gained update from 172.12.12.one on BRI0
06:05:34: subnet 172.twelve.thirteen.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
six:fourteen:53: RIP: been given v2 update from 172.23.23.3 on http://www.bbc.co.uk/search?q=토토사이트 Ethernet0
six:14:53: one.0.0.0/eight by way of 0.0.0.0 in sixteen hops (inaccessible)
6:fourteen:fifty three: one.one.1.one/32 by means of 0.0.0.0 in 2 hops
6:14:fifty three: 18.104.22.168/sixteen by using 0.0.0.0 in 16 hops (inaccessible)
six:fourteen:53: 172.twelve.twelve.2/32 by using 0.0.0.0 in two hops
six:14:53: 172.twelve.thirteen.0/thirty via 0.0.0.0 in one hops
6:14:fifty three: 172.twelve.123.0/24 via 0.0.0.0 in 1 hops
six:fourteen:53: 172.23.0.0/sixteen through 0.0.0.0 in sixteen hops (inaccessible)
Operate debug ip rip to troubleshoot routing update issues, RIP authentication troubles, and also to perspective the routing update contents. Crystal clear ip route * was operate to distinct the routing desk and also to drive a RIP update.
R2(config)#ip route 1.one.1.1 255.255.255.255 172.twelve.123.1
R2(config)#ip route one.1.one.one 255.255.255.255 serial0
To configure a static path to a specified destination IP handle, use the ip route command. The location is followed by a subnet mask, and that could be followed by possibly another-hop IP tackle or the exit interface on 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.twelve.123.one
R2(config)#ip route 0.0.0.0 0.0.0.0 ethernet0
To configure a default static route, use either of both of these commands.
You might have any number for the 1st 0.0.0.0″, given that the next set of zeroes could be the subnet mask. Which means that any location will match this route statement.
That’s an excellent overview to get rolling with! I’ll be again tomorrow with Section II of this CCNA Examination command overview!
