[f-nsp] VIPs on multiple subnets

[Diederik Schouten]

Hello,

There's only one routing table and no VRF's or something.

So as far as I know, you can't.

The "ip default-network" feature allows you to specify multiple backup gateways in case the default gw becomes unavailable.

The gateway to the network specified should already be in the routing table and thus the default-network can't be a locally defined network.

See it as:

If default gw becomes unavailable, route traffic towards the gateway normally used to reach network X, where network X = default-network.

Greetings,

   Diederik

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.
