here a configuration recovered from one of the first ipexpert volume 2
Configurations: R1: ---------------------------------------------------------------------- interface Dialer1 encapsulation ppp ip address negotiated dialer pool 12 dialer persistent ip mtu 1492 no shutdown ! interface FastEthernet0/0 no ip address pppoe-client dial-pool-number 12 no shutdown ! router ospf 1 network 0.0.0.0 0.0.0.0 area 0 ! R2: ---------------------------------------------------------------------- bba-group pppoe global virtual-template 12 ! ip local pool R1 12.12.12.100 12.12.12.100 ! interface virtual-template1 encapsulation ppp ip address 12.12.12.2 255.255.255.0 peer default ip address pool R1 ! interface GigabitEthernet0/0 no ip address pppoe enable group global no shutdown ! router ospf 1 network 12.12.12.0 0.0.0.255 area 0 R1#show ip ospf neighbor Neighbor ID Pri State Dead Time Address Interface 12.12.12.2 0 FULL/ - 00:00:22 12.12.12.2 Dialer1 Tp ypur router The problem of using ip address negotiated on the PPPoE client side is that it will use IPCP to negotiate the IP address and will always install the PPPoE Server's IP address and its own IP address as /32 routes. in RIP you can resolve this issue using interface command "no validate-update-source".. If you can switch by dhcp and then -ip add dhcp- under client and peer default ip address dhcp under virtual-template IP negotiation will follow dhcp's rule and you will have correct mask.
