Quick question: GRE and EIGRP

If I'm running EIGRP on a router and I would like to apply it on a GRE
tunnel that happens to be using some Ethernet interface, can I make the
Ethernet interface passive because I do not want it to participate in EIGRP
updates?

int Tunnel63
ip add 192.168.20.5 255.255.255.0
tunnel source fa0/0
tunnel destination 192.168.20.2
tunnel key 63

int FastEthernet0/0
ip address 192.168.20.1 255.255.255.0

router eigrp 4
network 192.168.20.0
passive-interface fa0/0
no auto-summary

Well, can I use the same network number for the tunnel AND the underlying
physical interface to begin with?

Also for EIGRP, can I use a mask the way I do with OSPF? I heard that
starting with some IOS release I can. Please verify.

Thanks
Tarek
