hi developers,

im trying to build a testbed for MIPv6 that was causing me some problems and i was wondering if i can get some helpful information from experts here. . .

i recompile the kernel, install umipv6 and build the patches aswel but when i create the mip6d.conf file to configure the home agent and mobile router for router advertisements and operations it gives me the problems and bul (binding update list) command does not work. the problem occurs at the step where i run the command "verbose yes" and "bul". when i run the command bul it says unknown command bul. i dont know where im missing something. i have already installed the required software and packages but still problems. . .radvd, automake, autoconf, flex, and all other package are already installed. . .the out put when i run the command NEMOD -c mip6d.conf is as follows.

SIOCSIFADDR: File exists
[May 04 16:49:58] radvd: radvd already running, terminating.
