Question

我有一台充当quagga路由器的VM主机。它宣布到托管虚拟机的路由（我不使用网桥，只使用路由虚拟机）

当tun接口配置为/ 30时，它运行良好;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

但我想在一些虚拟机上放置一些公开路由的IP，而不会浪费3个IP用于网络，广播和主机IP;例如：

$ ip ro
94.23.110.211 dev gentoo  scope link

该路线显示在“show ip route”quagga命令

中

arrakeen# show ip route

代码：K - 内核路由，C - 连接，S - 静态，R - RIP，O - OSPF， I - ISIS，B - BGP，＆gt; - 选择的路线，* - FIB路线

但正如你所看到的，它不在OSPF的fib

有没有办法强迫他们进入ospf？

这是ospfd.conf：

! -*- ospf -*-
!
hostname arrakeen
!
interface eth0
!
router ospf
 ospf router-id 10.42.42.21
 redistribute static
 redistribute connected

log file /var/log/quagga/ospfd.log

谢谢，

redistribute kernel失踪

如何使用quagga ospfd重新分配connected / 32？
