The solution is not to use a flow routing platform in the core. This
lesson was learnt at the end of the 90ties.
So until the linux ipv6 forwarding code is fixed to do stateless

I'd try increasing the routes max_size limit as a first step. If you're
running heavy traffic and/or full routes through a linux box, you're going
to need to do some tuning a

Discard them fast enough. ;)
The garbage collector is called if you reach the limit (in the code
path). But sometimes it cannot free enough entries. I

Does it mean the original route is keept or deleted?
Does it do for EVERY packet, i.e. EVERY packet generates a (temporary)
FIB entry???

No! Some boxes have Quagga, some - Bir
/proc/sys/net/ipv6/route/max_size - 10. Route table grows to 10
entries, and then drops to almost zero. Then cycle again.
But it should not be more than 14000, if mean both local and global
routes...

On the same box? Are they using the same routing table? I am fairly
confident that will end up in a fight.

Hi All,
I see the strange behaviour of my Linux routers. There are quagga and
bird with IPv6 BGP full view. Quagga/bird reports about 13500 prefixes,
but route table constantly grow up to 10 routes and more. Some
routes are duplicated 2,3,5 and even up to 20 times :( And after some
time routin

to my knowledge.
