You have a space after both interface Ethernet X commands that ties the Key
chain with the interface.
ip authentication key-chain eigrp 101 eigrpkey101
(Highlight the line to see what I mean)
It should look like this:
ip authentication key-chain eigrp 101 eigrpkey101
Unless that space appears in the key chain name itself, the authentication
string wont work.
