setting tunnel interface ip posted 11/20/2003

hello group,

Question
when creating tunnels over p2p links,
what is wrong with  setting the ip add of the tunnel
the same with the source interface of the tunnel...

example
R1--192.168.12.0/24---R2

r1
int se0
ip address 192.168.12.1 255.255.255.0
clock-rate 64000

int tun 0
tunnel source
se 0
ip unnumbered se 0
tunnel dest 192.168.12.2

r2
int se0
ip address 192.168.12.2 255.255.255.0


int tun 0
tunnel source se 0
ip unnumbered se 0
tunnel dest 192.168.12.1

such a config perfectly works.
and has no problems like recursive routing,
but everybody seem to grab another subnet from the allowed ip addresses,
or use ip unnumbered x where x !=se0,
to use with tunnel interface.
any comments is highly appreciated.
and one more thing...
in case i use a new subnet , should i filter it from the routing tables?
TIA
Ozgur
