Comment (by jostein):
Based on ticket here[1] I've added a tcpdump file of the ifup sequence,
using the following procedure.
Hopefully that might be helpful.
{{{
ifdown wan6
{ sleep 5; ifup wan6; } & tcpdump -i eth1 -w tcpdump.out ip6
}}}
Direct output can be observed here:
{{{
root@OpenWrt:~# ifdown wan6 & { sleep 5; ifup wan6; } & tcpdump -i eth1
ip6
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes
