EdgeOS BGP 路由已接收但未註入

我正在嘗試使用 Google Cloud Platform 通過 IPSEC 設置 BGP。IPSEC 隧道建立成功，GCP 報告 BGP 會話為 up。EdgeMax 路由器正在接收路由，但沒有將它們注入 RIB。

dan@router:~$ show ip bgp neighbors 169.254.0.1 received-routes
BGP table version is 7, local router ID is 169.254.0.2
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal
Origin codes: i - IGP, e - EGP, ? - incomplete

Total number of prefixes 1

dan@router:~$ show ip route

S    *> 192.168.42.0/24 [1/0] via 192.168.0.29, eth1

最初，本地路由器 ID 是我刪除的介面的地址，因此我將其更新為 169.254.0.2，但這並沒有幫助。

我的日誌看起來像這樣，每隔幾秒重複一次：

希望我只是缺少一件小事。誰能看到它是什麼？

我認為您需要啟用 4 的 ebgp 多路徑值

在這裡，我附上一個可以幫助您的配置：

$ show protocols bgp
bgp 65501 {
    neighbor 10.1.255.254 {
        ebgp-multihop 4
        remote-as 65515
        soft-reconfiguration {
            inbound
        }
        update-source 10.0.1.1
    }
    parameters {
        no-fast-external-failover
        router-id 10.0.1.1
    }
    redistribute {
        connected {
        }
    }
    timers {
        holdtime 180
        keepalive 60
    }
}
