Topic: Manual IPv6 Link Local adress

The content of this topic has been archived on 21 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hi,
Is it possible to configure OpenWRT to replace EUI-64 link-local address with manual one for one given interface?

Like it can be done on Cisco with interface level command:

ipv6 address fe80::1 link-local

It may not be possible to replace the EUI64 link-local address, but it's possible to have both by configuring the address in an interface. Why don't you want to use EUI64?

It is hard to remember EUI-64 address even for a few minutes, using fe80::1 will make troubleshooting/debugging less burdensome. E. g. it will be easy to see ND traffic from/to router in tcpdump output or see router address in 'ip -6 neigh' or 'ip -6 route' output.

And it is little advantage from an additional link-local address if it will not be used for RA/ND (and other traffic from link-local address).

The discussion might have continued from here.
