Problem is that redundancy doesn't work, probably a routing issue I need to get sorted out When 172.29.11.x net is down, neither node3 nor node4 is trying 172.29.12.x network,The problem lies in network 172.29.13.x
Code:
if 172.29.11.x network is down, node3/node4 should route to network 172.29.13.x over 172.29.12.x networkif 172.29.12.x network is down,node3/node4 should route to network 172.29.13.x over 172.29.11.x network
As we can see in the routing tables we do have two routes(through 12.x and 11.x) available for 13.x network .
Can you please help me understand is there way i am missing or need to add any other static routes to fix this issue
Code:

Reason: Please use code tags (and less formatting).
As a quick stab at this (and I've only had a brief look at AIX HA) I'm a little confused as to what you have. Code tags would make your output easier to read too.
Can you confirm:-
The primary/boot IP addresses on each card on each server, and that they can see each other.
Any permanent IP addresses added to the servers so you can guarantee which you are using.
The service IP addresses you have.
I think that you have public connections to a 172.29.1.xxx address, and that is the one that needs to be protected. If subnets 11, 12 or 13 drop off, you want to know about it and perhaps take some action. The subnet 172.29.1.xxx should be fault tolerant.
You do seem have a route defined from subnets 11/12 to 13, but I wonder why. Perhaps i am misreading what you intend.
Can you paste the output from ifconfig -a or whatever it is on Solaris these days. I've been over 10 years since I've had one to work on, lovely as they are. We would need to see the IP addresses, aliases (aliai? My Latin is not good) netmasks, gateways (contents of /etc/defaultrouter?)
A quick brief of which is which would be good too.
Thanks Robin, those are VIP used for fail-over for active and standby.
Just one more thing to re-phrase and a query.
We have two static entries in the route table for 13.x network via 11.x and 12.x. since 11.x is the first entry it generally prefer this path and even its try to route the packets its goes down(via 11.x).
wanted to know when it start to routes packets to 13.x to via 12.x and when will it assume that 11.x network is down and it has seek another best route to route the packets via 12.x .(below is the snippet of route table again)
Code:

Sorry, I didn't notice that only one is listed as UP. On AIX high-availability, the IP address is assigned only when failover is detected, hence my confusion.
I'm not sure that your 172.29.11.x addresses will re-route necessarily. If the service address you are offering is 172.29.12.15, then this should be the address for the default route out. You currently may have clients that target 172.29.12.15, but the return seems to be via 172.29.1.1 using card nge0 on each.
If you, from your own desk open a simple telnet or ssh connection to 172.29.12.15, what does your session show up as with the following:-
Code:
netstat -na | grep <your desk ip address>
netstat -nr | grep <your desk ip address>
I think that your routing may be all going out via nge0 except what is on the local subnet of each of the other cards.
Hopefully, I'm worrying unecessarily, but then I'm a bit stumped where you are getting stuck.
Hello
