default ipv6 route dissapears in pppoe client configuration

I have pretty simple IPv6 over PPPoE connection to ISP using SLAAC:

interface Dialer1

  ipv6 address autoconfig default

Initially everything works fine, but after 30 minutes default route disappears from my routing table. Obviously, my ISP does not send periodic RAs and does not provide long enough lifetime in its first (solicited) RA.

How can I keep default route in my routing table while PPPoE is up? Is there any way to send RS periodically?

I do not want to add permanent static route, because PPPoE is not always active.

i'm not aware of a command to change the RS advertisement or to some kind of cache change. I can't see other way to this without a default static route

ipv route ::/0 dialer1
