如何使用 quagga ospfd 重新分配連接的 /32？

我有一個充當 quagga 路由器的 VM 主機。它宣佈到其託管虛擬機的路由（我不使用網橋，只使用路由虛擬機）

當 tun 介面配置了 /30 時，它執行良好；例如 ：

$ ip a
4: gentoo: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 500
   link/ether 2a:c8:0a:ae:cc:c1 brd ff:ff:ff:ff:ff:ff
   inet 10.42.1.5/30 brd 10.42.1.7 scope global gentoo
   inet6 fe80::5c23:52ff:fec1:f2b7/128 scope link 
      valid_lft forever preferred_lft forever
   inet6 fe80::28c8:aff:feae:ccc1/64 scope link 
      valid_lft forever preferred_lft forever

但是我想在一些虛擬機上放置一些公共路由的 IP，而不會浪費 3 個 IP 用於網路、廣播和主機 IP；例如 ：

$ ip ro
94.23.110.211 dev gentoo  scope link 

路由顯示在“show ip route”quagga 命令中

arrakeen# show ip route  
Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF,

但正如你所見，它不在 OSPF 的 fib 中

有沒有辦法強迫他們進入 ospf ？

這是 ospfd.conf ：

! -*- ospf -*-
!
hostname arrakeen
!
interface eth0
!
router ospf
ospf router-id 10.42.42.21
redistribute static
redistribute connected
network 10.42.1.0/24 area 0
network 10.42.42.0/24 area 0
network 94.23.110.210/28 area 0
!
log file /var/log/quagga/ospfd.log

謝謝，

redistribute kernel成功了
