注意保持gobgpd和api端的版本一致性(為此下載了對應(yīng)的gobgpd二進(jìn)制執(zhí)行文件和源碼包)
https://www.janog.gr.jp/meeting/janog37/download_file/gobgp.pdf
環(huán)境：
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"
先安裝gobgpd服務(wù)端
apt install gobgpd -y
systemctl? stop gobgpd
下載gobgpd二進(jìn)制
wgethttps://github.com/osrg/gobgp/releases/download/v2.11.0/gobgp_2.11.0_linux_amd64.tar.gz
下載gobgpd源碼
wget https://github.com/osrg/gobgp/archive/v2.11.0.tar.gz
tar zxvf gobgp_2.11.0_linux_amd64.tar.gz
cp gobgpd /usr/bin/
cp gobgp? /usr/bin/
編輯/etc/gobgpd.conf
[global.config]
as = 65080
router-id = "10.5.245.122"
[[neighbors]]

? ? neighbor-address = "10.5.245.198"
? ? peer-as = 65060
? [[neighbors.afi-safis]]

? ? ? afi-safi-name = "ipv4-unicast"
啟動(dòng)gobgpd
systemctl restart gobgpd
確認(rèn)bgp鄰居已確立

開始API端的準(zhǔn)備與安裝
apt install protobuf-compiler -y
apt install python-minimal -y? ? ?
apt install python-pip -y
python -m pip install --upgrade pip
python -m pip install grpcio
python -m pip install grpcio-tools
注意以下三文件笙瑟，后面會被/root/gobgp/api/gobgp.proto調(diào)用
/usr/local/lib/python2.7/dist-packages/grpc_tools/_proto/google/protobuf/any.proto
/usr/local/lib/python2.7/dist-packages/grpc_tools/_proto/google/protobuf/empty.proto
/usr/local/lib/python2.7/dist-packages/grpc_tools/_proto/google/protobuf/timestamp.proto
解壓源碼
tar? zxvf? v2.11.0.tar.gz
mv gobgp-2.11.0 gobgp
cd? /root/gobgp/api/
python -m grpc_tools.protoc -I./ --python_out=. --grpc_python_out=. *.proto
export PYTHONPATH=$PYTHONPATH:/root/gobgp/api/
cd /root/gobgp/tools/grpc/python/
執(zhí)行python list_peer.py
執(zhí)行python add_path.py
（注意確保localhost:50051和179端口是open的）
在bgp對等體端查看 add_path.py執(zhí)行后的效果
