Hi, i have a problem with OSPF on PPP link.


I made a pptp server on 2801:


!

vpdn-group pptp

! Default PPTP VPDN group

accept-dialin

protocol pptp

virtual-template 2

!

interface Loopback2

ip address 10.35.14.1 255.255.255.255

!

interface Virtual-Template2

ip unnumbered Loopback2

ip ospf network point-to-point

peer default ip address pool pptp_pool

ppp authentication chap callin vpn

ppp authorization vpn

ppp accounting vpn

!

router ospf 1

router-id 10.1.0.2

redistribute connected subnets

network 10.0.0.0 0.255.255.255 area 0.0.0.0

!

ip local pool pptp_pool 10.35.14.100 10.35.14.200

!


now if i connect by windows pptp client, router installs peers route and redistribute it. if i connect from mpd client, router installs peers route as well, mpd host have quagga running with same osfp settings, and they establish full adjacency, but no routes are updated on mpd host, hovewer 2801 imports ospf routes from mpd host.


if i remove "redistribute connected subnets" fom 2801, then all peer routes are removed from export AND mpd host installs all ospf routes, he got from 2801. weird.

any ideas?

After checking once again, i found that mpd host doesn't receive routes at all at this setup.


if i configure virtual-template on server with ip address 10.35.14.0 255.255.255.0

only then mpd host receives routes, but that makes connection from other host breaking routing.
