Hi Tom,

I have the similar setup and I can ping by secondary IP in both direction.
I think you can i) Check whether router A has host route so that it won't
trust direct connected interface and vice versa; ii) Check whether the ARPs
are OK.

Thx,

Hi, group

    For testing the secondary ip, I connected several
routers on a switch.

Router A
interface Ethernet0
 ip address 11.10.10.1 255.255.255.0 secondary
 ip address 12.10.10.1 255.255.255.0 secondary
 ip address 14.10.10.1 255.255.255.0 secondary
 ip address 10.10.10.1 255.255.255.0
!

Router B
interface Ethernet0
 ip address 11.10.10.2 255.255.255.0

Router C
interface Ethernet0
 ip address 12.10.10.2 255.255.255.0

Router D
interface Ethernet0
 ip address 14.10.10.2 255.255.255.0

Router E
interface Ethernet0
 ip address 10.10.10.2 255.255.255.0

   B,C,D,E could ping A 's pair ip , But A couldn't ping
anyone.

WHY?
Does some have the same problem?

Thanks alot
