Part of finding out for CCNA exam success is keeping these new commands straight within your head! And let’s deal with it, There are many of commands you need to know in order to go the CCNA exam and generate that certification. Here’s a review of some extremely important distance vector and static routing commands you need to know, along with their good usage and console output.
Bandwidth
IGRP would make a default assumption that any Serial interface working IGRP is connected to a T1 line, which runs at 1544 KBPS. With equivalent-Price tag load-balancing enabled by default, This can be an undesirable assumption.
To alter IGRPs assumption, use the bandwidth command around the serial interface in query. Take note this command isn't going to really influence the bandwidth accessible to the interface; it merely improvements IGRPs assumption with the bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Crystal clear ip route *
This command clears your routing table of all non-static and non-linked routes. In the lab environment, its pretty helpful as it forces your routers jogging routing protocols to deliver and request updates, rather than looking ahead to the regularly scheduled updates.
R2#crystal clear ip route *
Debug ip igrp events
Debug ip igrp situations helps you to see IGRP updates remaining despatched and requested. Below, the debug is operate after which you can the routing table is cleared. The router immediately broadcasts update requests by way of the IGRP-enabled interfaces.
R2#debug ip igrp event
IGRP party debugging is on
06:02:fifty one: IGRP: broadcasting ask for on BRI0
06:02:51: IGRP: broadcasting request on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-Expense load-sharing with the variance command, youve received to grasp the metric with the a lot less-attractive routes. EIGRP retains these in its topology desk; IGRP has no these kinds of desk.
To get the metrics of routes not in the routing desk, operate debug ip igrp transactions. To drive IGRP updates, the 메이저사이트 routing table underneath was cleared with crystal clear 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.twelve.123.0, metric 10476 (neighbor 8476)
06:05:33: community 1.0.0.0, metric 8976 (neighbor 501)
06:05:33: IGRP: edition has become three
06:05:33: IGRP: sending update to 255.255.255.255 by using BRI0 (172.twelve.12.two)
06:05:33: network one.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 through Serial0.123 (172.twelve.123.two) – suppressing null update
06:05:34: IGRP: obtained update from 172.12.12.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
six:14:53: RIP: gained v2 update from 172.23.23.3 on Ethernet0
six:fourteen:fifty three: one.0.0.0/8 by means of 0.0.0.0 in 16 hops (inaccessible)
six:14:53: one.1.one.1/32 through 0.0.0.0 in 2 hops
6:14:53: 172.twelve.0.0/16 by means of 0.0.0.0 in sixteen hops (inaccessible)
6:14:fifty three: 172.12.twelve.two/32 by means of 0.0.0.0 in 2 hops
six:fourteen:fifty three: 172.twelve.13.0/30 via 0.0.0.0 in one hops
six:fourteen:fifty three: 172.twelve.123.0/24 by using 0.0.0.0 in one hops
6:14:53: 172.23.0.0/sixteen by means of 0.0.0.0 in sixteen hops (inaccessible)
Operate debug ip rip to troubleshoot routing update challenges, RIP authentication problems, also to view the routing update contents. Distinct ip route * was run to crystal clear the routing table and to power 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 1.1.one.one 255.255.255.255 serial0
To configure a static path to a presented desired destination https://www.washingtonpost.com/newssearch/?query=토토사이트 IP tackle, utilize the ip route command. The place is accompanied by a subnet mask, and that could be followed by either the next-hop IP address or the exit interface to the local 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 these two instructions.
You could have any quantity for the primary 0.0.0.0″, considering that the 2nd set of zeroes is definitely the subnet mask. Consequently any desired destination will match this route statement.
That’s a great overview to begin with! I’ll be again tomorrow with Part II of this CCNA exam command assessment!
