Hello

I created two virtual servers with FRR 6.0.2 installed on it..

Both has 3 interfaces
1st interafce is wan interafce
2nd and third interfaces are for test of eigrp..

1st server has this config
interface eth1
 ip address 192.168.100.1/24
!
router eigrp 100
 network 192.168.100.0/24
 network 192.168.200.0/24
 redistribute kernel
 redistribute connected



2nd server has;
interface eth1
 ip address 192.168.100.2/24
!
interface eth3
 ip address 192.168.200.2/24
 shutdown
!
router eigrp 100
 network 192.168.100.0/24
 network 192.168.200.0/24
 redistribute kernel
 redistribute connected
!



I can see the 192.168.200.0/24 routing on server1 via eigrp.. which is
nice..
The problem is,
if i shutdown the interface 2 on server2.. nothing happens..

centos1# conf t
centos1(config)# interface eth3
centos1(config-if)# shutdown
centos1(config-if)# end

and on sh run i have;
interface eth3
 ip address 192.168.200.2/24
 shutdown

but i can still ping this intrface from server1.
and on server2 ip addr output as follows;

6: eth3: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN group
default qlen 1000
    link/ether 62:9c:df:28:36:4a brd ff:ff:ff:ff:ff:ff
    inet 192.168.200.2/24 brd 192.168.200.255 scope global eth3
       valid_lft forever preferred_lft forever

It is really strange.
It seems shutdown command does not work.
