我从供应商处获得的信息如下。
Router ASN:AS56655
Router endpoint:2a03:94e0:f254::
Your endpoint:2a03:94e0:ffff:185:243:218::43
Multihop:Yes
Route table:Full
因此我进行了路线追踪。
root@debian:~# traceroute -s 2a03:94e0:ffff:185:243:218::43 2a03:94e0:f254::

事实上我的网关应该是2a03:94e0:ffff:185:243:218::1
我在 Bird2 中设置了静态路由。
protocol static {
ipv6;
route 2a03:94e0:f253::/128 via 2a03:94e0:ffff:185:243:218::2;
route 2a03:94e0:f254::/128 via 2a03:94e0:ffff:185:243:218::2;
route 2a12:f8c0:6960::/48 reject;
}
2a03:94e0:ffff:185:243:218::2修改为 后问题仍未解决2a03:94e0:ffff:185:243:218::1。
所有的路由都存储在lo中，导致网络无法访问。

其他 BGP 设置
template bgp bgppeers {
graceful restart on;
local as 142418;
default bgp_local_pref 100;
ipv4 {
import none;
export filter {
reject;
};
};
ipv6 {
import filter {
accept;
};
export filter {
reject;
};
};
}
protocol bgp terrahost_v6_rs1 from bgppeers {
source address 2a03:94e0:ffff:185:243:218::43;
neighbor 2a03:94e0:f254:: as 56655;
multihop 2;
ipv4 {
import none;
export none;
};
}
如何让路由存在于正确的接口（vmbr0）上。
root@debian:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

我已经花了一个多星期了，但还是找不到问题所在，所以我寻求帮助。
