Component of finding out for CCNA Examination achievements is holding each one of these new commands straight in your head! And Allow’s face it, There are plenty of commands you need to know so as to go the CCNA exam and generate 안전공원 that certification. Listed here’s a review of some extremely important length vector and static routing commands you need to know, in addition to their good use and console output.
Bandwidth
IGRP can make a default assumption that any Serial interface functioning IGRP is linked to a T1 line, which runs at 1544 KBPS. With equivalent-Value load-balancing enabled by default, This can be an undesirable assumption.
To alter IGRPs assumption, make use of the bandwidth command on the serial interface in dilemma. Notice this command does NOT essentially have an impact on the bandwidth accessible to the interface; it basically modifications 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-linked routes. Within a lab setting, its really handy since it forces your routers operating routing protocols to deliver and request updates, rather then waiting for the consistently scheduled updates.
R2#obvious ip route *
Debug ip igrp occasions
Debug ip igrp occasions enables you to see IGRP updates staying sent and requested. Listed here, the debug is run and then the routing desk is cleared. The router straight away broadcasts update requests by way of the IGRP-enabled interfaces.
R2#debug ip igrp function
IGRP party 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-Value load-sharing Using the variance command, youve acquired to understand the metric with the less-desirable routes. EIGRP retains these in its https://en.search.wordpress.com/?src=organic&q=토토사이트 topology desk; IGRP has no these types of table.
To find the metrics of routes not during the routing table, run debug ip igrp transactions. To pressure IGRP updates, the routing table under was cleared with very clear ip route *.
R2#debug ip igrp transactions
IGRP protocol debugging is on
06:05:33: IGRP: received update from 172.twelve.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: version is currently 3
06:05:33: IGRP: sending update to 255.255.255.255 by means of BRI0 (172.twelve.twelve.two)
06:05:33: community 1.0.0.0, metric=8976
06:05:33: IGRP: sending update to 255.255.255.255 through Serial0.123 (172.twelve.123.2) – suppressing null update
06:05:34: IGRP: been given update from 172.twelve.12.one on BRI0
06:05:34: subnet 172.twelve.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
6:fourteen:fifty three: RIP: obtained v2 update from 172.23.23.three on Ethernet0
6:14:53: one.0.0.0/eight through 0.0.0.0 in sixteen hops (inaccessible)
6:fourteen:fifty three: one.one.one.1/32 by way of 0.0.0.0 in two hops
6:fourteen:fifty three: 172.12.0.0/sixteen through 0.0.0.0 in sixteen hops (inaccessible)
6:14:53: 172.twelve.12.2/32 by way of 0.0.0.0 in 2 hops
six:fourteen:fifty three: 172.12.13.0/thirty by using 0.0.0.0 in one hops
six:14:fifty three: 172.12.123.0/24 by means of 0.0.0.0 in one hops
six:fourteen:53: 172.23.0.0/16 through 0.0.0.0 in sixteen hops (inaccessible)
Run debug ip rip to troubleshoot routing update complications, RIP authentication complications, and also to perspective the routing update contents. Distinct ip route * was operate to distinct the routing desk also to power a RIP update.
Ip route
R2(config)#ip route 1.one.one.one 255.255.255.255 172.12.123.1
OR
R2(config)#ip route 1.one.1.one 255.255.255.255 serial0
To configure a static path to a supplied vacation spot IP tackle, make use of the ip route command. The location is accompanied by a subnet mask, and which can be followed by either the next-hop IP tackle or perhaps the exit interface around 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.123.1
R2(config)#ip route 0.0.0.0 0.0.0.0 ethernet0
To configure a default static route, use either of these two instructions.
You might have any number for the main 0.0.0.0″, due to the fact the 2nd set of zeroes is the subnet mask. This means that any spot will match this route assertion.
That’s a great assessment to get going with! I’ll be back tomorrow with Component II of this CCNA Examination command critique!
