I have a router with ethernet interfaces configured as below:

ip address 192.168.31.202 255.255.255.0 secondary
ip address 10.132.0.254 255.255.255.0

and attached to LAN 192.168.31.0/24

Can it send icmp messages obtaining answers to 192.168.31.0/24 IP addresses?

From my PC 192.168.31.30 I can ping the router but ther router doesn't ping me.
I swithed on the "debug ip icmp" but when pinged from my PC I see debug messages but I can't when the router send icmp
packets to me.

The ping only works if I use extended ping.
The same for tftp: I can use tftp only if the server is in the same LAN of the main IP address of the router.
It seems to the router uses always the main IP of the interface.
Is it normal?

Alex.
