Hi all
I'm still not sure quagga is free from bugs in this area, but I do know
what caused our issues.
/proc/sys/net/ipv6/route/max_size < current IPv6 table.
Would it be wise to have quagga check maximum number of routes (IPv4 and
IPv6) and show this in some way?
Also, does anybody know what happens when the maximum is reached?
Does the kernel write over the oldest entries (link local etc)?
