Part of learning for CCNA examination success is keeping all these new instructions directly in your head! And lets face it, there are a lot of commands you need to know in order to pass the CCNA exam and make that certification. Here is a review of some extremely important distance vector and static routing instructions you should know, with their appropriate usage and system output. Bandwidth IGRP makes a default assumption that any Serial screen working IGRP is attached to a T1 line, which runs at 15-44 KBPS. With equal-cost load-balancing enabled automatically, this may be a prediction. To change IGRPs prediction, make use of the bandwidth command on the serial interface under consideration. Note that this control does NOT actually affect the bandwidth available to the interface; it simply changes IGRPs prediction of the bandwidth. R2#conf t R2 config #int s0 R2 config-if #bandwidth 5-12 Obvious internet protocol address path * This command clears your routing dining table of most non-connected and non-static channels. In a lab environment, its very practical because it makes your routers working routing protocols to request and send updates, instead of awaiting the regularly scheduled updates. R2#clear internet protocol address way * De-bug ip address igrp activities Debug ip igrp activities allows you to see IGRP updates being sent and requested. Here, the debug is run and then a routing dining table is removed. Learn more on our related essay - Click here: [http://perry-belcher.doomby.com/ company web site]. The switch immediately shows upgrade demands via the interfaces. Click here [http://perry-belcher.webs.com/ perry belcher site] to read why to mull over it. R2#debug internet protocol address igrp event IGRP event debugging is on R2#clear ip course * 06:02:51: IGRP: broadcasting request o-n BRI0 06:02:51: IGRP: broadcasting request o-n Serial0.123 Debug ip address igrp transactions Youve got to understand the full of the paths, to change IGRP unequal-cost load-sharing with the alternative command. EIGRP keeps these in its topology table; IGRP does not have any such dining table. To have the measurements of channels maybe not in the routing table, function de-bug ip address igrp transactions. The routing table below was satisfied with clear internet protocol address route *, to force IGRP changes. R2#debug internet protocol address igrp transactions IGRP protocol debugging is o-n R2#clear internet protocol address course * On Serial0.123 06:05:33: IGRP: acquired update from 172.12.123.1 06:05:33: subnet 172.12.123.0, full 10476 neighbor 8476 06:05:33: system 1.0.0.0, full 8976 neighbor 501 06:05:33: IGRP: model is currently 3 06:05:33: IGRP: sending update to 255.255.255.255 via BRI0 172.12.12.2 06:05:33: community 1.0.0.0, metric=8976 06:05:33: IGRP: sending update to 255.255.255.255 via Serial0.123 172.12.123.2 - suppressing null update 06:05:34: IGRP: received update from 172.12.12.1 o-n BRI0 06:05:34: subnet 172.12.13.0, metric 160250 friend 8476 06:05:34: community 1.0.0.0, metric 158750 neighbor 501 Debug ip split R2#debug internet protocol address grab IP protocol debugging is o-n R2#clear internet protocol address path * O-n Ethernet0 6:14:53: RIP: received v-2 update from 172.23.23.3 6:14:53: 1.0.0.0/8 via 0.0.0.0 in 1-6 hops unavailable 6:14:53: 1.1.1.1/32 via 0.0.0.0 in 2 hops 6:14:53: 172.12.0.0/16 via 0.0.0.0 in 1-6 trips inaccessible 6:14:53: 172.12.12.2/32 via 0.0.0.0 in 2 hops 6:14:53: 172.12.13.0/30 via 0.0.0.0 in 1 hops 6:14:53: 172.12.123.0/24 via 0.0.0.0 in 1 hops 6:14:53: 172.23.0.0/16 via 0.0.0.0 in 16 hops unavailable Work debug internet protocol address rip to troubleshoot routing update problems, RIP validation problems, and to look at the routing update articles.

Ip path R2#conf t R2 config #ip route 1.1.1.1 255.255.255.255 172.12.123.1 OR R2 config #ip option 1.1.1.1 255.255.255.255 serial0 To configure a static route to a given destination IP address, make use of the ip route command. The location is followed by a subnet mask, and that may be followed by both the next-hop IP or the exit program to the local switch. Ip address course 0.0.0.0 0.0.0.0 R2#conf t R2 config #ip route 0.0.0.0 0.0.0.0 172.12.123.1 OR R2 config #ip option 0.0.0.0 0.0.0.0 ethernet0 To change a default static route, use either of these two directions. You can have any number for your first 0.0.0.0, considering that the second set of zeroes may be the subnet mask. This implies that any destination can match this course record.
