AltostratusGateway Failsafe and default gateways
Hi,
I am quite lost concerning how Gateway Failsafe (GF) can be used to monitor def GW in cluster.
Def GW object is object synced between nodes. So I can't see a way to set two different De...
Greetings, Following this article and it appears the LTM is aware of the fact that the device is in a high-availability configuration.

I modified the pool (per article) and when tab completing, options of the device names for the devices in the HA pair. This seems to be how the system differentiates:
modify ltm pool ssh_pool gateway-failsafe-device
Configuration Items:
ltm2.test.net ltm1.test.net
This is an example using route domains based on this description (I believe):
"So one is going out VLAN1 -> GW1 -> Internet second VLAN2 -> GW2 -> Internet based just on routing table."
Two route domains:
net route-domain 0 {
id 0
vlans {
internal
}
}
net route-domain rd2 {
id 2
vlans {
external
}
}
Two pools based on the route domains:
ltm pool pool_0 {
members {
10.12.23.27:any {
address 10.12.23.27
session monitor-enabled
state up
}
}
monitor gateway_icmp
}
ltm pool pool_2 {
members {
10.11.23.27%2:any {
address 10.11.23.27%2
session monitor-enabled
state up
}
}
monitor gateway_icmp
}
Now the route table, showing two default gateway. Any packet to vlan internal will route to pool_1 and any packet in vlan external will go to pool_2:
show net route
----------------------------------------------------------------------------------------
Net::Routes
Name Destination Type NextHop Origin
----------------------------------------------------------------------------------------
gateway_0 default pool /Common/pool_0 static 1500
gateway_2 default%2 pool /Common/pool_2 static 1500
There are so many options for managing pools and routes, I would like to think this won't be impossible. It may just take a few tries.
