if file is big this one will be faster:

Code:
#!/usr/bin/perl -w

open(FH,"somefile");
open(NEW,">newfile");
while(<FH>){
    if(/: (network\d+?)$/){print NEW "\n$1";next}
    /: (\d+)$/;print NEW ":$1"
}

also work with any number of lines without modification while last one contain Failed RADIUS Acc

ip6rtrd

ip6rtrd(8)						      System Manager's Manual							ip6rtrd(8)

NAME

       ip6rtrd - IPv6 routing daemon

SYNOPSIS

       /usr/sbin/ip6rtrd [-dD] [-l logfile] [configfile]

OPTIONS

       Enables additional debugging information, such as bad packets received, to be logged.  The ip6rtrd daemon remains under control of the host
       that started it; therefore, an interrupt from the controlling host stops the ip6rtrd process.  Same as the -d option, but does not run as a
       daemon.	 Specifies  a log file into which ip6rtrd writes information about its actions.  The log contains information about any changes to
       the routing tables and a history of recent route change messages sent and received that are related to changed routes.  If you do not spec-
       ify a log file, information is logged to stdout.

DESCRIPTION

       The  ip6rtrd  daemon  sends  IPv6 Router Advertisement (RA) packets of the Neighbor Discovery Protocol.	These packets enable any listening
       host to autoconfigure itself without manual intervention.  In addition, you can configure ip6rtrd to send and process RIPng messages.

       At startup, the ip6rtrd daemon reads its default configuration file for startup information.  If you used ip6_setup to  configure  IPv6	on
       your  system, the configuration file is /etc/ip6rtrd.conf.  You can specify an alternate configuration file by using the configfile parame-
       ter.

   Signals
       The following signals have the specified effect when sent to the ip6rtrd process using  the  kill(1)  command:  Displays  internal  routing
       tables.	 If a log file is specified, the routing information is logged to it.  Terminates the ip6rtrd process.	Before exiting, the daemon
       removes any system state that was configured by the daemon, including default routers and on-link prefixes.  In addition, the daemon broad-
       casts RIPng packets with hop counts set to infinity over the appropriate interfaces.

									    Caution

	      Do not use SIGKILL to terminate the ip6rtrd process, as this may leave the system's IPv6 configuration in an inconsistent state.

RESTRICTIONS

       Do not run the nd6hostd and ip6rtrd daemons on the same host as this may produce unpredictable results.
