Element of studying for CCNA Test success is holding these new commands straight in the head! And Allow’s encounter it, there are a lot of instructions you have to know in an effort to pass the CCNA Test and gain that certification. Here’s an evaluation of some extremely important distance vector and static routing instructions you need to know, in conjunction with their correct utilization and console output.
Bandwidth
IGRP helps make a default assumption that any Serial interface running IGRP is linked to a T1 line, which runs at 1544 KBPS. With equivalent-Price load-balancing enabled by default, this may be an undesirable assumption.
To change IGRPs assumption, use the bandwidth command about the serial interface in problem. Note this command doesn't essentially impact the bandwidth accessible to the interface; it merely modifications IGRPs assumption in the bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Clear ip route *
This command clears your routing desk of all non-static and non-connected routes. In a very lab atmosphere, its quite handy mainly because it forces your routers functioning routing protocols to send out and request updates, rather then looking forward to the routinely scheduled updates.
R2#apparent ip route *
Debug ip igrp activities
Debug ip igrp occasions permits you to see IGRP updates being sent and asked for. Here, the debug is run and after that the routing desk is cleared. The router straight away broadcasts update requests via the IGRP-enabled interfaces.
R2#debug ip igrp occasion
IGRP celebration debugging is on
06:02:fifty one: IGRP: broadcasting ask for on BRI0
06:02:fifty one: IGRP: broadcasting ask for on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-cost load-sharing Using the variance command, youve acquired to understand the metric from the considerably less-fascinating routes. EIGRP keeps these in its topology table; IGRP has no these kinds of desk.
To obtain the metrics of routes not during the routing desk, run debug ip igrp transactions. To power IGRP updates, the routing table down below was cleared with distinct ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: received update from 172.twelve.123.one on Serial0.123
06:05:33: subnet 172.12.123.0, metric 10476 (neighbor 8476)
06:05:33: community 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 using BRI0 (172.12.12.two)
06:05:33: network one.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 by way of Serial0.123 (172.12.123.2) – suppressing null update
06:05:34: IGRP: obtained update from 172.12.twelve.1 on BRI0
06:05:34: subnet 172.12.13.0, 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
six:14:53: RIP: received v2 update from 172.23.23.three on Ethernet0
6:fourteen:fifty three: one.0.0.0/eight by way of 0.0.0.0 in 16 hops (inaccessible)
6:14:53: 1.1.1.one/32 by way of 0.0.0.0 in two hops
6:fourteen:53: 172.twelve.0.0/16 via 0.0.0.0 in https://www.washingtonpost.com/newssearch/?query=토토사이트 sixteen hops (inaccessible)
6:fourteen:fifty three: 172.12.12.2/32 by way of 0.0.0.0 in two hops
6:14:fifty three: 172.twelve.13.0/30 through 0.0.0.0 in 1 hops
six:fourteen:53: 172.12.123.0/24 through 0.0.0.0 in one hops
6:14:fifty three: 172.23.0.0/16 through 0.0.0.0 in sixteen hops (inaccessible)
Run debug ip rip to troubleshoot routing update challenges, RIP authentication issues, also to see the routing update contents. Apparent ip route * was run to clear the routing table also to drive a RIP update.
Ip route
R2(config)#ip route one.one.one.one 255.255.255.255 172.twelve.123.1
OR
R2(config)#ip route one.one.one.one 255.255.255.255 serial0
To configure a static path to a presented desired destination IP handle, utilize the ip route command. The location is accompanied by a subnet mask, and which can be accompanied by possibly the following-hop IP tackle or maybe the exit interface within the regional router.
Ip route 0.0.0.0 0.0.0.0
R2(config)#ip get more info route 0.0.0.0 0.0.0.0 172.12.123.1
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 might have any selection for the main 0.0.0.0″, since the second set of zeroes could be the subnet mask. Consequently any location will match this route assertion.
That’s a fantastic evaluation to get started with! I’ll be again tomorrow with Element II of this CCNA Examination command review!
