===== Code =====

Remember to clear your browser cache before downloading :)

  * {{:cobgp:cogui.pl|GUI code}} (Perl for quagga)
  * {{:cobgp:monitorco.pl|monitor}} (Perl. Can be used with Asterisk, GnuGK, Cisco (you can use Cisco for CO-BGP instead of quagga), Yate. Can be easily extended.)
  * {{:cobgp:monitorcobgp.tcl|monitorcobgp}} (TCL, can be run by Embedded Event Manager (EEM)) [[.:cisco_tcl_eem|Cisco TCL/EEM mini-howto]] (older version {{:cobgp:monitorco.tcl|monitor}})
  * {{:cobgp:chf.agi|CHF code}}  (Perl. The code implements the lookup function and the "glue" to make it work with Asterisk.) Note: You must also have the monitor script (the previous bullet) running with subroutine write_plaintext. It will populate an intermediate CO-table (at the moment a plain text file "COtable.txt", you can easily make it use a database also). The CHF will use the intermediate table instead of the CO-BGP table directly (Option 6).
  * {{:cobgp:routecall.zip|CHF code}} (C. Implements the lookup function, as well as Asterisk FastAGI "bindings".). Note: You must also have the monitor script (the previous bullet) running with subroutine write_plaintext. It will populate an intermediate CO-table (at the moment a plain text file "COtable.txt", you can easily make it use a database also). The CHF will use the intermediate table instead of the CO-BGP table directly.
  * {{:cobgp:net_ip.pl|Convert}} an IPv6 prefix to a telephony prefix (and vice versa; Perl)

===== Configuration =====

==== Asterisk (tested in Linux Debian 6.0) ====

  * {{:cobgp:sip.conf|sip.conf}}
  * {{:cobgp:h323.conf|h323.conf}}
  * {{:cobgp:extensions.conf|extensions.conf}}
  * {{:cobgp:modules.conf|modules.conf}}

==== GnuGK (tested in Linux Debian 6.0) ====

  * See guidelines in the comments of the monitor code (above subroutine write_gnugk).

==== Yate (tested in Linux Debian 6.0) ====

  * See guidelines from the monitor code (above subroutine write_yate).

==== Cisco ISR 2921 ====

  * {{:cobgp:cisco_isr_bgp.txt|Cisco ISR BGP configuration}}. NOTE: In this configuration the CO-BGP neighbor (in this example ''10.10.5.12'') and the "normal" eBGP neighbor (''10.63.0.2'') are handled from the same router. In other words, **no dedicated "CO-BGP router" is needed**.
  * {{:cobgp:cisco_isr_voice.txt|Cisco ISR voice configuration example}}.

==== Quagga ====

**Debian** (in this example configuration, CO-BGP and the "normal" BGP are handled from the same process): 
  * {{:cobgp:bgpd.conf|/etc/quagga/bgpd.conf}}
  * {{:cobgp:interfaces.txt|/etc/network/interfaces}}
  * {{:cobgp:debian.conf|/etc/quagga/debian.conf}}
  * {{:cobgp:zebra.conf|/etc/quagga/zebra.conf}}

**CentOS:** Same as with Debian.

**Note that no IPv4 networks are advertised to CO-BGP neighbor (10.10.0.12), and no IPv6 networks to CL-BGP neighbor (10.63.0.1):**  
<code bash>
# vtysh -c 'show ip bgp neighbors 10.63.0.1 advertised-routes' 
> 10.10.5.0/24     10.63.0.2     0     32768 i  
# vtysh -c 'show ipv6 bgp neighbors 10.63.0.1 advertised-routes'
% No such neighbor or address family
# vtysh -c 'show ip bgp neighbors 10.10.0.12 advertised-routes'
# vtysh -c 'show ipv6 bgp neighbors 10.10.0.12 advertised-routes' 
*&gt; 2001:db8:941:215::/64                                             2001:db8::10:10:5:12                                                                                       0 32768 i
