>Description:
My pppoe connection, which uses PAP and provides a static IP,
usually looks like this:

pppoe0: flags=8851<UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST> mtu 1492
        inet 206.183.9.221 -> 0.0.0.1 netmask 0xff000000
        inet6 fe80::2a0:24ff:fe5c:75f2%pppoe0 -> :: prefixlen 64 scopeid 0xa

Occasionally, it goes down, printing the following message to the console:

pppoe0: LCP keepalive timed out, going to restart the connection

When this message occurs, I'd expect the connection to be reestablished
shortly. However, this never happens. Rebooting the machine always
restores the connection.

In a previous discussion with Martin, he noted that at least two
wrong things occur during IP negotiation: we suggest that the remote
peer be 0.0.0.1, and it agrees!

$ ifconfig pppoe0
pppoe0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1492
        inet 0.0.0.0 -> 0.0.0.0 netmask 0xff000000
        inet6 fe80::2a0:24ff:fe5c:75f2%pppoe0 -> :: prefixlen 64 scopeid 0xa

>How-To-Repeat:
Connect to my local ISP's DSL service using NetBSD's pppoe(4). Wait
an arbitrary period of time (usually days to weeks). Discover that
the network connection has fallen, and can't get up.

>Fix:
None provided, sorry.
