[f-nsp] VIPs on multiple subnets

[Tom Banner]

I'm running an si450 with router code (boot image 10.2) and can't get VIPs on multiple subnets to work.

I have 3 default networks defined (ip default-network). One /24 and two /29 networks. I also have a default route for the /24 defined. 

When the default route is in place, only the /24 VIPs work.  If I remove the default route, VIPs on all three networks work but there is a slight delay. If I reboot the si450 then none of the VIPs work. It seems the routes are cached when I remove the default route, which makes it all work but unreliably. 

How can I have VIPs in 3 different subnets with their own gateway?
