Part of researching for CCNA Examination accomplishment is maintaining every one of these new instructions straight inside your head! And Allow’s confront it, There are plenty of http://edition.cnn.com/search/?text=토토사이트 commands you need to know to be able to pass the CCNA Test and make that certification. In this article’s an assessment of some vital distance vector and static routing commands you have to know, in addition to their appropriate usage and console output.
Bandwidth
IGRP can make a default assumption that any Serial interface jogging IGRP is connected to a T1 line, which operates at 1544 KBPS. With equivalent-Charge load-balancing enabled by default, This can be an undesirable assumption.
To change IGRPs assumption, use the bandwidth command within the serial interface in problem. Be aware that this command doesn't truly have an effect on the bandwidth accessible to the interface; it merely changes IGRPs assumption of your bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Apparent ip route *
This command clears your routing table of all non-static and non-connected routes. In the lab environment, its incredibly handy since it forces your routers jogging routing protocols to mail and request updates, rather than awaiting the consistently scheduled updates.
R2#crystal clear ip route *
Debug ip igrp situations
Debug ip igrp situations lets you see IGRP updates currently being despatched and requested. Listed here, the debug is operate after which 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 request on BRI0
06:02:51: IGRP: broadcasting request on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-cost load-sharing Together with the variance command, youve acquired to know the metric of the fewer-desirable routes. EIGRP keeps these in its topology desk; IGRP has no these types of table.
To obtain the metrics of routes not while in the routing table, run debug ip igrp transactions. To pressure IGRP updates, the routing desk under was cleared with distinct ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: gained update from 172.12.123.one on Serial0.123
06:05:33: subnet 172.12.123.0, metric 10476 (neighbor 8476)
06:05:33: network one.0.0.0, metric 8976 (neighbor 501)
06:05:33: IGRP: edition is currently 3
06:05:33: IGRP: sending update to 255.255.255.255 by means of BRI0 (172.12.twelve.two)
06:05:33: community one.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 via Serial0.123 (172.12.123.2) – suppressing null update
06:05:34: IGRP: gained update from 172.twelve.twelve.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
six:fourteen:fifty three: RIP: been given v2 update from 172.23.23.3 on Ethernet0
six:14:53: one.0.0.0/eight through 0.0.0.0 in 16 hops (inaccessible)
6:14:fifty three: 1.one.one.one/32 by using 0.0.0.0 in two hops
six:fourteen:fifty three: 172.12.0.0/16 by means of 0.0.0.0 in sixteen hops (inaccessible)
six:14:53: 172.12.twelve.two/32 by using 0.0.0.0 in 2 hops
six:14:fifty three: 172.twelve.thirteen.0/thirty by way of 0.0.0.0 in one 토토사이트 hops
six:fourteen:53: 172.12.123.0/24 by using 0.0.0.0 in 1 hops
six:fourteen:fifty three: 172.23.0.0/sixteen via 0.0.0.0 in 16 hops (inaccessible)
Run debug ip rip to troubleshoot routing update challenges, RIP authentication challenges, also to watch the routing update contents. Obvious ip route * was operate to distinct the routing desk and to pressure a RIP update.
Ip route
R2(config)#ip route 1.1.one.one 255.255.255.255 172.twelve.123.one
OR
R2(config)#ip route one.1.one.1 255.255.255.255 serial0
To configure a static route to a offered location IP address, use the ip route command. The place is followed by a subnet mask, and which can be accompanied by both another-hop IP tackle or perhaps the exit interface over the area 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 could have any number for the primary 0.0.0.0″, given that the 2nd list of zeroes will be the subnet mask. Which means any destination will match this route assertion.
That’s a fantastic evaluation to get started with! I’ll be back tomorrow with Part II of the CCNA Examination command critique!
