BMP とは「BGP Monitoring Protocol」のことで、現在は標準化に向けて IETF のドラフト段階 (draft-17) にあります。
BMP サーバの実装はまだ数が少ないようですが、今回は ryu に付随する BMP サーバを IOSv、XEv、XRv、Junos と組み合わせて試してみます。
NX-OSv も試してみたのですが、後述の通り BMP の設定が出来ませんでした。
検証環境
構成
VIRL 上で以下の構成を作り、検証しました。10.1.0.0/24 側のネットワークは BMP サーバ/クライアント間の通信用、10.2.0.0/24 側のネットワークは eBGP Peering 用です。
BMP サーバは Ubuntu を使いました。BMP サーバをインストールする為、インターネットへ接続出来るようにしておきます。
$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.2 LTS"クライアント側は以下の OS を使いました。
| ルータ | バージョン |
|---|---|
| IOSv | 15.6(1) |
| CSR 1000v (IOS-XE) | 15.6(1)S |
| IOS-XRv | 6.0.0 |
| NX-OSv | 7.2(0)D1(1) |
| Junos | 14.1R1.10 |
Linux の設定
BMP クライアントと接続するインターフェイスのアドレスだけ、設定しておきます。BMP サーバは後の手順でインストールします。
sudo ip addr add 10.1.0.100/24 dev eth1
sudo ip link set up dev eth1IOSv の設定
デフォルトでは BMP サーバとのコネクションを開始する値を示す initial-delay が 600 秒になっていました。検証環境では早めに BMP サーバとコネクションを確立して欲しいので、initial-delay 30 を設定してあります。

BGP 機能を使う為、license grace-period で評価ライセンスを有効化しておきます。
switch(config)# license grace-periodインターフェイスや BGP の設定は以下の通りです。しかし、Cisco の公式サイトを調べたのですが、現状の NX-OS では BMP がサポートされていないのか、設定コマンドを見つけることが出来ませんでした。2014/9/16 公開の BGP Monitoring Protocol の P.6 には「N3K, N7K, N9K: TBD」と記載されていました。もしかすると現時点でも NX-OS では BMP が未実装なのかも知れません。
