‘cisco’ CCNP / BCSI Quiz Tutorial: Configuring EIGRP Bundle Authentication

By Steve | November 7, 2011

Configuring RIPv2 and EIGRP authentication with key rings is often complicated at first, and the syntax is just not just memorable. Nevertheless for BSCI and CCNP audit accomplishment, we’ve got as a way to conduct this task.

In a previous guide, we got how you can manage RIPv2 package authentication, with equally very clear-wording and MD5 authentication schemes. EIGRP authentication is a very similar, and it has the writing and MD5 authentication solutions at the same time. But EIGRP currently being EIGRP, the order just needs to be a bit more thorough!

As with RIPv2, the authentication mode should be approved by the EIGRP friends and neighbors. For more router’s user interface is configured for MD5 authentication and the remote control router’s user interface is configured for wording authentication, the adjacency will don’t succeed choice . two connects under consideration are configured to use precisely the same password.

We’ll now manage hyperlink authentication about the adjacency above an Ethernet phase. Underneath, you’ll see how you can manage the key chain termed EIGRP on routers, use major # 1, and rehearse the important thing-string BSCI. Manage show major chain using a wireless router to find out all key rings.

Key-chain EIGRP:

key 1 — wording "BSCI"

accept life long (usually appropriate) – (usually appropriate) [appropriate now]

send life long (usually appropriate) – (usually utorrent appropriate) [appropriate now]

R3(config)Numbermajor chain EIGRP

R3(config-keychain)Numbermajor 1

R3(config-keychain-major)Numbermajor-string BSCI

R3Numbershow major chain

Key-chain EIGRP:

key 1 — wording "BSCI"

accept life long (usually appropriate) – (usually appropriate) [appropriate now]

send life long (usually appropriate) – (usually appropriate) [appropriate now]

The EIGRP order to make use of the important thing chain is a ache to reflect upon, because protocol so when selection is determined down the middle of the order, not the first. Also note that two instructions are required Body to mention the important thing chain, one more to explain the authentication mode in use.

As with RIPv2, the prevailing adjacency was torn decrease when one for whites was configured with authentication. Should the major chain is effectively explained and put on all parties, the adjacency is up. Constantly run show internet protocol eigrp next door neighbor to make sure the adjacency occurs. Understand the information on EIGRP key rings by configuring them for your property clinical tools, and you’ll be above ready for BSCI audit accomplishment!
