IPMP group failure when gateway not detected

A problem happened with me, I was configuring IP for two network interfaces, and when I rebooted the system, everything is working but after like 3 or 5 minutes it will tell me that the whole IPMP group has failed !

I tried to troubleshoot, so I found that the gateway is not reachable..so I deleted the /etc/defaulrouter file and I removed the gateway using route delete commands, and I rebooted, it's working fine now.

I just want to confirm from you guys that if the gateway is not reachable the IPMP group fails ?

It happened to me when we were relocating some servers, T2000, V245..
If the DNS/Gateway is having some issues, both failed, but sometimes its due to the way you configure the IPMP in the hostname.interface files

this is how i configured my /etc/hostname.e1000g0

oracle-n1 netmask + broadcast + group ipmp1 up \
addif n1-test deprecated netmask + broadcast + -failover up

any advice ?

how abt your other interface?

You should use something like this:

Create the /etc/hostname.e1000g0
group server-int
set 192.168.2.9/24 broadcast + up
addif 192.168.2.109/24 broadcast + deprecated -failover up

Create the /etc/hostname.e1000g1
group server-int
set 192.168.2.209/24 broadcast + -failover deprecated standby up
