Section of finding out for CCNA Examination success is retaining all of these new instructions straight in the 사설사이트 head! And Permit’s confront it, There are plenty of commands you have to know so as to go the CCNA Examination and get paid that certification. Listed here’s an evaluation of some extremely important length vector and static routing instructions you need to know, in conjunction with their proper use and console output.
Bandwidth
IGRP helps make a default assumption that any Serial interface managing IGRP is linked to a T1 line, which runs at 1544 KBPS. With equal-cost load-balancing enabled by default, this may be an undesirable assumption.
To alter IGRPs assumption, utilize the bandwidth command over the serial interface in dilemma. Notice this command doesn't in fact affect the bandwidth available to the interface; it simply changes IGRPs assumption of your bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Clear ip route *
This command clears your routing table of all non-static and non-related routes. Inside of a lab setting, its incredibly handy since it forces your routers functioning routing protocols to ship and ask for updates, rather than expecting the frequently scheduled updates.
R2#clear ip route *
Debug ip igrp occasions
Debug ip igrp activities allows you to see IGRP updates getting sent and asked for. Right here, the debug is operate then the routing desk is cleared. The router straight away broadcasts update requests by means of the IGRP-enabled interfaces.
R2#debug ip igrp function
IGRP party 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 With all the variance command, youve received to be aware of the metric from the a lot less-desirable routes. EIGRP keeps these in its topology desk; IGRP has no these kinds of table.
To obtain the metrics of routes not during the routing table, operate debug ip igrp transactions. To force IGRP updates, the routing table underneath was cleared with apparent ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: received update from 172.12.123.1 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: version is currently 3
06:05:33: IGRP: sending update to 255.255.255.255 by means of BRI0 (172.12.12.2)
06:05:33: network 1.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 by means 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.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
6:14:fifty three: RIP: been given v2 update from 172.23.23.3 on Ethernet0
six:fourteen:53: 1.0.0.0/eight by means of 0.0.0.0 in sixteen hops (inaccessible)
six:14:53: 1.1.one.1/32 by way of 0.0.0.0 in 2 hops
6:fourteen:53: 172.twelve.0.0/16 by means of 0.0.0.0 in 16 hops (inaccessible)
six:fourteen:53: 172.12.twelve.two/32 by using 0.0.0.0 in two hops
six:14:53: 172.twelve.13.0/thirty by using 0.0.0.0 in 1 hops
6:14:fifty three: 172.12.123.0/24 by using 0.0.0.0 in 1 hops
6:14:53: 172.23.0.0/sixteen by way of 0.0.0.0 in 16 hops (inaccessible)
Run debug ip rip to troubleshoot routing update difficulties, RIP authentication issues, also to perspective the routing update contents. Obvious ip route * was operate to very clear the routing desk and to pressure a RIP update.
Ip route
R2(config)#ip route 1.1.one.1 255.255.255.255 172.twelve.123.1
OR
R2(config)#ip route one.one.1.1 255.255.255.255 serial0
To configure a static path to a provided vacation spot IP handle, make use of the ip route command. The spot is accompanied by a subnet mask, and which might be accompanied by either the following-hop IP tackle or perhaps the exit interface within 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 possibly of both of these commands.
You might have any amount for the 1st 0.0.0.0″, considering that the 2nd list of zeroes may be the subnet http://edition.cnn.com/search/?text=토토사이트 mask. Consequently any destination will match this route statement.
That’s a fantastic critique to start out with! I’ll be back tomorrow with Aspect II of this CCNA Test command evaluate!
