Hello,
Since last friday, my FTTE internet access was cut and my servers run
with a radio backup that has triggered an issue in my IPv6
configuration. When I have read again my NetBSD ipv6 configuration, I
have found something I don't understand. Please note that this
configuration ran fine.
ISP gives me 2a0a:1c84:1000:a00::/56 adresses. 2a0a:1c84:1000:a00::1 is
IPv6 gateway. Between Cisco's routers and servers, I have configured
2a0a:1c84:1000:a00::/64 network.
Thus, in a linux box, I have written :
iface wan0 inet6 static
address 2a0a:1c84:1000:a00::2
netmask 64
gateway 2a0a:1c84:1000:a00::1
pre-down /sbin/ip -6 route del unreachable 2a0a:1c84:1000:a00::/56
post-up /sbin/ip -6 route add unreachable 2a0a:1c84:1000:a00::/56
In NetBSD side :
legendre# cat ifconfig.wm2
tcp6csum udp6csum
inet6 2a0a:1c84:1000:a00::3 prefixlen 64 alias
mtu 1500
up
!route add -inet6 default 2a0a:1c84:1000:a00::1
Thus, wm2 (2a0a:1c84:1000:a00::3/64) is connected to Cisco that serves
2a0a:1c84:1000:a00::/56. Linux server solves this with unreachable
routes. But I don't have this route on NetBSD side. Normal or not ?

JB
