hello all:
i have a few question concerning ip directed-broadcast and ip
forward-protocol.. best way for me to ask is as follows:
suppose a question worded like this:
configure r1 to forward mobile-ip packets arriving on the atm 1/0 interface to
10.10.10.1
so if one does this..
!
ip forward-protocol udp mobile-ip
!
interface ATM1/0
ip address 20.20.20.1 255.255.255.0
ip helper-address 10.10.10.1
1:
will it work? (cannot test mobile-ip in my lab)
2:
having configured "ip forward-protocol udp mobile-ip", will this ONLY forward
udp mobile-ip ?
or, will it still forward all of the "default" udp ports [dhcp-discover
(bootp), netbios, etc..] enabled by the "ip helper-address " command?
3:
should this type of question be interpreted as ONLY forward udp mobile-ip ?
{ask proctor maybe??}
if so, should the following be added to the above config:
!
access-list 150 per udp any any eq mobile-ip
!
interface ATM1/0
ip directed broadast 150
(never really understood this mobile-ip stuff)
thanks
rob
