GoBGP integration

We have complete GoBGP integration for unicast IPv4.

We have following configuration options for GoBGP:

gobgp = off
gobgp_next_hop = 0.0.0.0
gobgp_announce_host = on
gobgp_announce_whole_subnet = off

We haven't enabled GoBGP build by default because it needs really huge dependency list.

Please use following reference:

wget https://raw.githubusercontent.com/FastVPSEestiOu/fastnetmon/master/src/fastnetmon_install.pl -Ofastnetmon_install.pl 

Open fastnetmon_install.pl file and replace my $enable_gobgp_backend = ''; by my $enable_gobgp_backend = '1';.

sudo perl fastnetmon_install.pl --use-git-master

Create example configuration for GoBGPD in gobgpd.conf file in current directory:

[global.config]
  as = 65001
  router-id = "213.133.111.200"

[[neighbors]]
  [neighbors.config]
    neighbor-address = "10.10.10.250"
    peer-as = 65001

    [neighbors.ebgp-multihop.config]
      enabled = true

    [[neighbors.afi-safis]]
      afi-safi-name = "ipv4-unicast"        

Run it:

/opt/gobgp_1_0_0/gobgpd -f gobgpd.conf

Check announced routes:

/opt/gobgp_1_0_0/gobgp global rib 
    Network             Next Hop             AS_PATH              Age        Attrs
*>  192.168.1.1/32      0.0.0.0                                   00:00:08   [{Origin: ?}]

Announce custom route:

gobgp global rib add 10.33.0.0/24 -a ipv4

Withdraw route (please be careful! FastNetMon do not expect this from your side):

gobgp global rib del 10.33.0.0/24 -a ipv4
