Component of studying for CCNA Examination achievements is keeping each one of these new commands straight within your head! And Allow’s face it, There are many of commands you have to know in an effort to pass the CCNA Test and generate that certification. Right here’s an evaluation of some vital length vector and static routing commands you need to know, along with their correct utilization and console output.
Bandwidth
IGRP would make a default assumption that any Serial interface jogging IGRP is connected to a T1 line, which operates at 1544 KBPS. With equal-Value load-balancing enabled by default, This can be an unwanted assumption.
To alter IGRPs assumption, make use of the bandwidth command about the serial interface in problem. Be aware this command won't really have an effect on the bandwidth accessible to the interface; it merely variations IGRPs assumption on the bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Crystal clear ip route *
This command clears your routing desk of all non-static and non-connected routes. In a very lab atmosphere, its extremely helpful since it forces your routers operating routing protocols to send and request updates, as an alternative to watching for the often scheduled updates.
R2#distinct ip route *
Debug ip igrp occasions
Debug ip igrp activities helps you to see IGRP updates being despatched and asked for. Right here, the debug is operate after which the routing desk is cleared. The router immediately broadcasts update requests by using the IGRP-enabled interfaces.
R2#debug ip igrp event
IGRP occasion debugging is on
06:02:51: IGRP: broadcasting request on BRI0
06:02:51: IGRP: broadcasting request on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-Charge load-sharing with the variance command, youve bought to know the metric from the fewer-appealing routes. EIGRP keeps these in its topology desk; IGRP has no such desk.
To obtain the metrics of routes not within the routing desk, operate debug ip igrp transactions. To power IGRP updates, the routing desk below was cleared with apparent ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: been given 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 now 3
06:05:33: IGRP: sending update to 255.255.255.255 by means of BRI0 (172.12.12.two)
06:05:33: network 1.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 by using Serial0.123 (172.twelve.123.2) – suppressing null update
06:05:34: IGRP: obtained update from 172.12.twelve.one on BRI0
06:05:34: subnet 172.12.13.0, 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:fourteen:53: RIP: been given v2 update from 172.23.23.three on Ethernet0
6:14:53: 1.0.0.0/eight by using 0.0.0.0 in sixteen hops (inaccessible)
six:14:53: one.1.1.1/32 by using 0.0.0.0 in two hops
six:14:fifty three: 172.12.0.0/sixteen by means of 0.0.0.0 in sixteen hops (inaccessible)
6:14:53: 172.twelve.12.2/32 by means of 0.0.0.0 in 2 hops
six:14:fifty three: 172.twelve.13.0/30 via 0.0.0.0 in 1 hops
6:fourteen:fifty three: 172.twelve.123.0/24 by using 0.0.0.0 in 1 hops
six:fourteen:fifty three: 172.23.0.0/16 via 0.0.0.0 in 16 hops (inaccessible)
Operate here debug ip rip to troubleshoot routing update challenges, RIP authentication troubles, also to look at the routing update contents. Distinct ip route * was run to apparent the routing desk and to pressure a RIP update.
Ip route
R2(config)#ip route 1.one.one.1 255.255.255.255 172.twelve.123.one
OR
R2(config)#ip route one.one.one.one 255.255.255.255 serial0
To configure a http://www.bbc.co.uk/search?q=토토사이트 static path to a presented location IP address, utilize the ip route command. The desired destination is followed by a subnet mask, and that could be followed by possibly the subsequent-hop IP deal with 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.123.1
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 could have any quantity for the 1st 0.0.0.0″, given that the next set of zeroes will be the subnet mask. Therefore any destination will match this route statement.
That’s a good overview to get going with! I’ll be back tomorrow with Aspect II of this CCNA exam command assessment!
