No IPv6 address on PPPoE Interface

[mahescho]

Hi,

I've three WAN interfaces, one static and two PPPoE Interfaces. All interfaces with static IPv4 and IPv6 addresses. IPv6 works with the static and the first PPPoE interface. The new, second PPPoE interface receives it's static IPv4 address by PPPoE. As with the first PPPoE interface I've configured the IPv6 address manually as static but it does not get assigned to the interface pppoe1.

Any suggestions how to fix this?

TIA

Firmware: latest 18,7

Now I've tried to set it manually:

Code Select Expand


pppoe1: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1484
inet6 fe80::290:bff:fe6d:aa96%pppoe1 prefixlen 64 scopeid 0x16
inet6 fe80::290:bff:fe6d:aa92%pppoe1 prefixlen 64 scopeid 0x16
inet xx.xx.xx.xx --> xx.xx.xx.xx  netmask 0xffffffff
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
root@fw:~ # ifconfig pppoe1 inet6 xx:xx:xx:xx::1 prefixlen 64 alias
ifconfig: ioctl (SIOCAIFADDR): File exists

No success ...

"File exists" would indicate it works, but it's not displayed by the OS.

Interesting and true. When I ping the IP I can see the ICMP echo requests on the interface. That I do not see the replies is a problem with the gateway, but it works.

... but it's not displayed by the OS.

Pretty unusual, isn't it? Some kind of bug?

Possibly, something to check the 19.1-BETA against or have a look at https://bugs.freebsd.org/bugzilla/

I can't take a closer look at the moment.

A fix...

As described in the bug report.

I would like to point out referring to random bugs isn't helping.

We already established it looks like a OS issue with the ifconfig display...
