- By default, the Cisco router will not forward BOOTP requests
- (UDP broadcats). You must configure the Cisco router to forward
- these UDP broadcasts.
-
- This can be done by using the ip forward-protocol global con-
- figuration command and an ip helper-address. The ip forward-
- protocol command allows you to specify protocols and ports to
- be forwarded by the router. The ip helper-address defines the
- destination host to receive the UDP broadcasts.
-
- I believe that bootp is amoung the protocols that are forwarded by
- default when a helper-address has been specified.
-
- It's worth adding that the cisco routers DO fill in the protocol
- fields within the bootp packet as described in the RFC (eg it is not
- a simple forwarding of the raw packet - we provide the additional
- info that is necessary for the bootp server to be able to send the
- reply back to the host that issued the bootp request.)
