5.2.4.1 IP Destination Address
If:
- the destination address in the IP header is one of the addresses of
the router,
- the packet contains a Source Route Option, and
- the pointer in the Source Route Option does not point past the end
of the option,
then the next IP Destination Address is the address pointed at by the
pointer in that option. If:
- the destination address in the IP header is one of the addresses of
the router,
- the packet contains a Source Route Option, and
- the pointer in the Source Route Option points past the end of the
option,
then the message is addressed to the system analyzing the message.
A router MUST use the IP Destination Address, not the Ultimate
Destination Address (the last address in the source route option),
when determining how to handle a packet.
It is an error for more than one source route option to appear in a
datagram. If it receives such a datagram, it SHOULD discard the
packet and reply with an ICMP Parameter Problem message whose pointer
points at the beginning of the second source route option.
