Component of researching for CCNA Test results is trying to keep these new instructions straight within your head! And let’s deal with it, There are tons of instructions you need to know to be able to pass the CCNA exam and generate that certification. In this article’s a review of some important distance vector and static routing instructions you need to know, together with their appropriate usage and console output.
Bandwidth
IGRP can make a default assumption that any Serial interface jogging IGRP is linked to a T1 line, which operates at 1544 KBPS. With equivalent-Price tag load-balancing enabled by default, this may be an unwanted assumption.
To change IGRPs assumption, make use of the bandwidth command within the serial interface in concern. Notice that this command won't truly have an affect on the bandwidth available to the interface; it merely alterations IGRPs assumption of the bandwidth.
R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512
Distinct ip route *
This command clears your routing desk of all non-static and non-connected routes. In a lab atmosphere, its extremely helpful because it forces your routers jogging routing protocols to ship and ask for updates, as opposed to looking forward to the frequently scheduled updates.
R2#crystal clear ip route *
Debug ip igrp functions
Debug ip igrp occasions means that you can see IGRP updates staying sent and asked for. Listed here, the debug is operate then the routing desk is cleared. The router right away broadcasts update requests by using the http://www.thefreedictionary.com/토토사이트 IGRP-enabled interfaces.
R2#debug ip igrp event
IGRP event debugging is on
06:02:fifty one: 메이저사이트 IGRP: broadcasting request on BRI0
06:02:51: IGRP: broadcasting ask for on Serial0.123
Debug ip igrp transactions
To configure IGRP unequal-cost load-sharing With all the variance command, youve got to grasp the metric on the a lot less-fascinating routes. EIGRP retains these in its topology table; IGRP has no these types of table.
To have the metrics of routes not in the routing desk, run debug ip igrp transactions. To force IGRP updates, the routing desk underneath was cleared with obvious ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: obtained 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: edition has become 3
06:05:33: IGRP: sending update to 255.255.255.255 by means of BRI0 (172.12.twelve.2)
06:05:33: community one.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 by way of Serial0.123 (172.twelve.123.two) – suppressing null update
06:05:34: IGRP: gained update from 172.twelve.twelve.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
six:fourteen:fifty three: RIP: been given v2 update from 172.23.23.3 on Ethernet0
6:14:fifty three: one.0.0.0/eight via 0.0.0.0 in sixteen hops (inaccessible)
six:14:53: 1.1.one.1/32 via 0.0.0.0 in two hops
6:14:fifty three: 172.12.0.0/16 via 0.0.0.0 in 16 hops (inaccessible)
six:14:53: 172.twelve.12.two/32 through 0.0.0.0 in 2 hops
6:14:fifty three: 172.twelve.thirteen.0/thirty by means of 0.0.0.0 in 1 hops
6:14:fifty three: 172.12.123.0/24 by way of 0.0.0.0 in one hops
six:14:53: 172.23.0.0/16 by means of 0.0.0.0 in sixteen hops (inaccessible)
Run debug ip rip to troubleshoot routing update complications, RIP authentication challenges, also to view the routing update contents. Distinct ip route * was operate to crystal clear the routing table and also to power a RIP update.
Ip route
R2(config)#ip route one.one.one.one 255.255.255.255 172.12.123.1
OR
R2(config)#ip route 1.one.one.1 255.255.255.255 serial0
To configure a static route to a offered desired destination IP deal with, utilize the ip route command. The desired destination is accompanied by a subnet mask, and that may be followed by either another-hop IP address or perhaps the exit interface over the nearby 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 might have any selection for the 1st 0.0.0.0″, considering the fact that the 2nd set of zeroes will be the subnet mask. Therefore any place will match this route assertion.
That’s a very good evaluate to get rolling with! I’ll be back again tomorrow with Component II of the CCNA Test command assessment!
