I have a question about routing and ICMP. Can ICMP redirects be used to update
routing tables or does it just convey info about a route not being appropriate?
Example would be to have an X terminal on a network 90. talking to a host A
also on net 90. Then I introduce yet another host B which has two(2) network
interface cards that bridge 90 to say net 89. I then put host A on net 89 and 
provide it with a new 89 internet number. Question then is can the X terminal
find the gateway to host A via ICMP only or will rip or gated need to be 
provided on the X terminal to update route tables????

Thanks in advance.... David Wingo  wingo@ncrcae.Columbia.NCR.COM
