This is done with Heartbeat (Linux-HA). What would be the advantage of 
FreeVRRP?

They are.

Well, the interfaces are configured as "default-system-config" in the 
interfaces {} block, the fea {} block contains only the forwarding config, 
and the ip addresses are configured in the ospf4 {} block of the protocols 
{} block. I have taken that from the "Getting Started" document on 
xorp.org.
Do you suppose to use a different structure?

And the question remains: How do I make an additional IP address on a 
certain interface known to xorp?

Thanks for helping!
