[c-nsp] Strange NAT and DHCP Problem

Found a similar post on NSP in Feb 2009.

Need the command "ip dhcp bootp ignore" but this isn't supported on the
7600.

Hi Charles,

Tried what you suggested but no go.

no ip bootp server
clear ip dhcp binding <IP>

Client has obtained an "infinite" lease again.

172.16.75.119    0021.e9a0.777c          Infinite
Automatic

Cheers.

Andy

The infinite DHCP entry is probably a BOOTP client, which doesn't have
the concept of a lease.  There are knobs (ip dhcp bootp ignore) that can
turn off bootp, and only allow DHCP.  I think by default, it'll service
both.
