6. Enable IP Source Routing
The router examines IP header options on every packet. It supports the IP header options Strict Source
Route, Loose Source Route, Record Route, and Time Stamp, which are defined in RFC 791. If the
router finds a packet with one of these options enabled, it performs the appropriate action. If it finds a
packet with an invalid option, it sends an ICMP Parameter Problem message to the source of the
packet and discards the packet. If it finds error in source routing process, it will send and ICMP
unreachable (source routing failed) message to the source host.
IP provides a provision allowing the source IP host to specify a route through the IP network. This
provision is known as source routing. Source routing is specified as an option in the IP header. If source
routing is specified, the router forwards the packet according to the specified source route. This feature
is employed when you want to force a packet to take a certain route through the network. The default is
to perform source routing.
You can enable IP source-route header options by performing the following command task in global
configuration directory:
ip source-route
[DEFAULT@router /config/]#ip

Please Input the code of command to be excute(0-26): 23
input 23，Select source-route option .
7. Allow IP Fast Exchange
IP Fast Exchange uses routing buffer memory to relay IP message. When relaying the first message to
a certain destination, the system will examine routing table and ralay the message with the route. And
then the route will be kept in the routing buffer memory. Afterwards messages received by this host will
be relayed according to the route in buffer against query of routing table. System won't create routing
