How to Configuring EIGRP Stub Area Networks

More router you has you has more of query and more of query and delay you has more big of opportunities in you of network in the of router will became SIA (stuck activities), in this situation Xia does not in specifies of thread returns query of replies of any continuous of EIGRP node held will was dropped, through that neighbors learn to of any routing will also from delete routing table even route has. In the worst cases, such problems may result in your routing table go away.

With all these information tables; R5 when you really need it has only one entrance into the net on the upstream network query? This certainly is not. R5, be the primary candidate, in this case become a stub (stub), EIGRP router receives all routes, but only the advertising connections and total route upstream.

Another router when the router has been formed with the stub (stub) neighborhood adjacent to the stub (stub), EIGRP neighbors will not be sent any queries so this effectively accelerates network convergence, because there is now a small router route fault condition s.

There are seven different types of EIGRP stub (stub) but CCNA scope coves only basic stub (stub), is sent only EIGRP routes will receive all connection and summary routes. The list of the different types of stub (stub) that EIGRP can be configured for the network;

CCNA exam only requires you to be familiar with the basics of EIGRP stub (stub) operation, but you can try if you want to further your knowledge with other EIGRP stub (stub) type.

To configure EIGRP stub (stub) type, navigate to EIGRP router configuration mode, and then use the EIGRP stub (stub) command.

You can verify that the neighbor is a stub (stub) neighbors in privileged mode using the show IP EIGRP neighbor detail command.

R4 and R5 is a branch office in this lab is a regional office. R5 has only a single network, its route is 10.80.50.0/24. You will act as a configure EIGRP stub router R5 and verify that your configuration.

Be familiar with the following new command;

• Configure R5 as an EIGRP stub network to send connected and summary routes only to its neighboring router(s)
• Verify R5′s EIGRP stub router configuration using only R4.

Step 1: Configure the R5 and summary routes to its neighboring routers send connector only EIGRP stub (stub) network.

There are two different commands you can use to accomplish this goal, to do the same thing. First EIGRP stub (stub), which is by default EIGRP stub (stub) and will send a summary of connections and routes, or you can use the EIGRP stub (stub) connection, a summary of which will give you the same results. This lab will show by default EIGRP stub (stub) types, as shown below;

R5>enable

R5#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

R5(config)#router eigrp 10

R5(config-router)#eigrp stub

R5(config-router)#end

R5#

%SYS-5-CONFIG_I: Configured from console by console

%DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor 10.80.45.1 (Serial0/1)

is down: peer info changed

R5#

%DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor 10.80.45.1 (Serial0/1)

is up: new adjacency

R5#

Step 2: Verify using only R4 ′ s EIGRP stub (stub) the router configuration.

To view instead, or neighbor is not EIGRP stub router in privileged mode using the show IP EIGRP neighbor detail command, as shown below.
