Here is my configuration

Before offset-list update the FD is 2198016 for 10.1.1.4/30 and the below list showing FD & AD (2198016/2195456)
Now take look at after offset-list update. The FD is 2198016, the below list showing FD & AD (2198026/2195456). So my question is why it is showing FD is 2198016, it suppose to show 2198026 like in (2198026/2195456).
And also CCNP Official Cert Guide say the offset-list value is add to computed to FD and AD, but in some blogs the offset-list value is add/computed in delay. which one correct?

Hi
Please let me take a look of your output,The offset-list is an feature used to modify the composite metrics in EIGRP. The value configured in the offset-list command is added to the delay value calculated by the router for the route matched by an access-list. An offset-list is the preferred method to influence a particular path that is advertised and/or chosen.

Hello,
issue a 'clear ip eigrp neighbors'. After applying the offset list, the topology database should look like this:
P 10.1.1.4/30, 1 successors, FD is 2198026 <<<<==================
via 192.168.1.2 (2198026/2195456), FastEthernet1/0

Hi,
As George mentioned you can refresh the neighborship, sometime it is not updated immediately.
