Subject: AUTHENTICATION ERROR Multiple Key ids within key chain EIGRP
I have the following scenario:
R1, R3, R5 connected to the frame-relay cloud with router 3 acting as the
Frame relay Hub and R1 and R5 as the spokes.
We have a single network/24 between frame relay interfaces, using eigrp as
the routing protocol.
The task prompts to authenticate the sessions between the spokes an the hub,
in the following fashion:
R3 (the hub), must authenticate with R1 using password "CISCO13" (key id 13)
R3 (the hub), must authenticate with R5 using password "CISCO35" (key id 35)
So In the HUb router I create two keys within the key chain called EIGRP,
numbering KEY 1 with the password CISCO13, and KEY 2 with the password
CISCO35.
At the spokes I only create a key chain also called EIGRP, matching Key id
"13" with its password In R1, and key id "35" in R5.
I only consider to authenticate and form EIGRP adjacency between ROUTER3 AND
ROUTER 1, but Theres is no way to form adjacency between ROUTER 3 and ROUTER
5.
Doing a debug at R5 about eigrp packetes I see R3 is only sending key id 13,
and not key id 35, to ROUTER5.
Anyone please knows what am I missing??
any help would appreciate a lot.
