Secondary Ip address

I have 2 networks ...

a) 192.168.70.0

b) 192.168.71.0

One router ethernet interface has been configured --

ip address 192.168.70.3 255.255.255.0

ip address 192.168.71.1 255.255.255.0 secondary

Another router ethernet interface has been configured ----

ip address 192.168.70.4 255.255.255.0

there is no secondary ip address assigned to this router ,,

192.168.70.3 is a default gateway IP for HOSts in network 192.168.70.0

and 192.168.71.1 is default gateway IP for hosts in network 192.168.71.0

now i have a problem that HOst inside network 192.168.71.0 cannot PING to

second router ethernet IP 192.168.70.4

how to fix it ?

Re: Secondary Ip address

Try "ip route-cache same-interface", it should help routing between the primary and secondary interface.

Also, in terms of routing and as a FYI take a look at : http://www.cisco.com/warp/public/105/41.html

Hope it helps.

Re: Secondary Ip address

I just re-read your original post and missed something the first time.

How does 192.168.70.4 know how to get back to the 192.168.71.0 network?

Solution: Add a secondary address (eg. 192.168.71.2) to the second router or add a route on the second router to 192.168.71.0 via 192.168.70.4.

Once this is done I would add ip route-cache same-interface to improve performance.

Let me know if it works.

Thanks
