Bird 1.6.3 path prepending ?

[Pieter De Wit]

Sorry, I did forget that off the email:

bird> show route 192.168.7.0/24
192.168.7.0/24     via 10.255.255.101 on ppp1 [bgp_site_1 07:50:22] * (100) [AS65101i]

Should that last section not contain all the numbers ? 

That command was ran on the VPN server btw :)
