Routing daemon not working properly?

[B.Bonev]

routed can't route my ppp connection
FreeBSD 4.8 Release
Is any other information is needed?
How can I solve problem?
router# Jun 12 11:26:03 router routed[63]: IP_ADD_MEMBERSHIP ALLHOSTS: can't
assign requested address
router# Jun 12 11:26:03 router routed[63]: setsockopt (IP_ADD_MEMBERSHIP
RIP): can't assign requested address
router# Jun 12 11:26:03 router routed[63]: ignore RTM_CHANGE without mask
router# Jun 12 11:26:03 router routed[63]: ignore RTM_CHANGE without mask

Thanks
