[AusNOG] 2811 IPv6 routing table limit

[Matthew Moyle-Croft]

Hi,

Do you end up with a full table on each though?  Or partial?  Does each peer have a route to the next hop?

I'm trying to received two full IPv6 tables and I'm only getting to around 10,000 routes. each feed is between 9500 - 9900 so a fully table and then about 100 from the other feed. I've checked the memory, that isn't the issue. Any thoughts?
