HI,
I think that A should be able to ping router E atleast. The reason it is not
able to ping other routers is, that by default A uses its primary ip address
as its source IP, and since the other routers do not have a clue of how to
reach the 10 network, they are not able to reply to the packet. Whereas for
A all the networks are in the routing table and so he sends the reply back
out of E0.
debug ip packet will help you to make the picture clear.
Smiles,
Mohit.

Subject: Ping the Secondary IP
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?
