Key chain is individual concept, Key string common?

CMIIW.

Judging from my task experience, I began to think the above.

In Task 5.4 EIGRP, BB1 and R6 are going to make authentication.

.

BB1:

Key chain EIGRP

 Key 1

  Key-string CISCO

.

R6:

Key chain MD5_KEYS

 Key 1

  Key-string CISCO

.

They authenticated with each other.

Key-string must be identical.

CISCO must be CISCO.

‘CISCO ‘  will not be allowed.

.

However, Key chain name does not need to be identical.

.

Or not?

  • If I understand your question correctly. Key number and Key-string has to be same on both the sides because router applies a hash function on Key number + key-string and matches this hash output from the other side hash output value.

    Key chain name need not to be identical on both side.

    Perfect explanation!

  • Just as a side note, In RIP the key number could be different but ofcourse password/key-string should be same. Sometimes it gives problems until you put send and accept lifetime perameters. With OSPF concept is same like EIGRP though but watch out for magic of Null Key in ospf which can bring your peering up still.
