Sorry but... It's not working for me. what am I missing?

I type the following:

c1720#c
Enter configuration commands, one per line. End with CNTL/Z.
c1720(config)#router eigrp 1
c1720(config-router)#distrib
c1720(config-router)#distribute-list 1 in null 0
c1720(config-router)#^Z
c1720#sb router e

Nov 8 08:52:52.208 PST: %SYS-5-CONFIG_I: Configured from console by console

When I looked at the code under eigrp 1 it does NOT show!

c1720#sb router e
router eigrp 1
 redistribute ospf 10 metric 10000 20000 255 1 1
 redistribute eigrp 2
 passive-interface FastEthernet0
 network 192.168.3.0
 no auto-summary
!
