bgp-update-create is a small program used to generate the payload of a BGP UPDATE message. It was written to test if routes could be injected in a BGP conversation between two routers.
It's usage is very simple; it takes three parameters:
--as: Autonomous System number
--nexthop: Host name or IP address of next hop
--destnet: Network number/prefix to advertise
To use it with tcphijack you just pipe its output to tcphijack, like in:
sudo bgp-update-create --as 2 --nexthop 1.1.1.1 --destnet 2.2.2.2 | \ tcphijack [...]
or just send its output to a file and then use tcphijack's -P switch to specify a payload:
bgp-update-create --as 2 --nexthop 1.1.1.1 --destnet 2.2.2.2 > payload.dat
sudo tcphijack [...] -P payload.dat
bgp-update-create is built at the same time as tcphijack (by typing "make"), the header files used by bgp-update-create.c come from the Zebra project.
