probable side effects of deleting interfaces ip addresses(loopback ones) from routing table !

[h bagade]

Hi all,

I've deleted the interface ip address from routing table and only keep the
network address. Nothing is behaving unusual afterwards. I think this
loopback ip address is added for better performance. My question is would I
get in to trouble by deleting these ip addresses from routing table or
it's, as I think, just a matter of performance?

Thanks in advance
