針對來自第 0 層路由器在上行運作的路由,則必須備妥與 Top-of-Rack 裝置的連線。

必要條件

程序

  1. 登入 NSX Edge CLI。
  2. NSX Edge 上執行 get logical-routers 命令,以尋找第 0 層服務路由器的 VRF 號碼。
    nsx-edge-1> get logical-routers
    Logical Router
    UUID        : 736a80e3-23f6-5a2d-81d6-bbefb2786666
    vrf         : 0
    type        : TUNNEL
    
    Logical Router
    UUID        : 421a2d0d-f423-46f1-93a1-2f9e366176c8
    vrf         : 5
    type        : SERVICE_ROUTER_TIER0
    
    Logical Router
    UUID        : f3ce9d7d-7123-47d6-aba6-45cf1388ca7b
    vrf         : 6
    type        : DISTRIBUTED_ROUTER
    
    Logical Router
    UUID        : c8e64eff-02b2-4462-94ff-89f3788f1a61
    vrf         : 7
    type        : SERVICE_ROUTER_TIER1
    
    Logical Router
    UUID        : fb6c3f1f-599f-4421-af8a-99692dff3dd4
    vrf         : 8
    type        : DISTRIBUTED_ROUTER
    
    
  3. 執行 vrf <number> 命令,以進入第 0 層服務路由器內容。
    nsx-edge-1> vrf 5
    nsx-edge1(tier0_sr)> 
    
  4. 在第 0 層服務路由器上執行 get route 命令,以確定預期的路由會顯示在路由表中。
    請留意 TOR 的路由會顯示為已連線 (c)。
    nsx-edge1(tier0_sr)> get route
    Flags: t0c - Tier0-Connected, t0s - Tier0-Static, b - BGP,
    t0n - Tier0-NAT, t1s - Tier1-Static, t1c - Tier1-Connected,
    t1n: Tier1-NAT, t1l: Tier1-LB VIP, t1ls: Tier1-LB SNAT,
    t1d: Tier1-DNS FORWARDER, t1ipsec: Tier1-IPSec, isr: Inter-SR,
    > - selected route, * - FIB route
    
    Total number of routes: 11
    
    t1c> * 1.1.1.0/25 [3/0] via 100.64.1.1, downlink-282, 08w4d03h
    t1c> * 1.1.2.0/24 [3/0] via 100.64.1.1, downlink-282, 08w4d03h
    t0c> * 1.1.3.0/24 is directly connected, downlink-275, 08w4d03h
    b  > * 2.1.4.0/24 [20/0] via 40.40.40.10, uplink-273, 01w0d02h
    b  > * 10.182.48.0/20 [20/0] via 40.40.40.10, uplink-273, 01w0d02h
    t0c> * 40.40.40.0/24 is directly connected, uplink-273, 08w4d03h
    t0c> * 100.64.1.0/31 is directly connected, downlink-282, 08w4d03h
    t0c> * 169.254.0.0/24 is directly connected, downlink-277, 01w0d02h
    b  > * 172.17.0.0/16 [20/0] via 40.40.40.10, uplink-273, 01w0d02h
    t0c> * fc36:a750:db0d:7800::/64 is directly connected, downlink-282, 08w4d03h
    t0c> * fe80::/64 is directly connected, downlink-282, 08w4d03h
    
  5. 探測 TOR。
    nsx-edge1(tier0_sr)> ping	192.168.100.254
    PING 192.168.100.254 (192.168.100.254): 56 data bytes
    64 bytes from 192.168.100.254: icmp_seq=0 ttl=64 time=2.822 ms
    64 bytes from 192.168.100.254: icmp_seq=1 ttl=64 time=1.393 ms
    ^C
    nsx-edge1>
    --- 192.168.100.254 ping statistics ---
    3 packets transmitted, 2 packets received, 33.3% packet loss
    round-trip min/avg/max/stddev = 1.393/2.107/2.822/0.715 ms
    

結果

此時系統會在第 0 層邏輯路由器與實體路由器之間傳送封包以確認連線。

後續步驟

您可以根據網路需求來設定靜態路由或 BGP。請參閱在管理程式模式中設定靜態路由在管理程式模式中的第 0 層邏輯路由器上設定 BGP
