EDIT: I made a mistake in my config below. I was testing, and removed the mtu 1492 from the server. Interesting that it still works. Only the client has the problem. I can ping from loopback to loopback in both directions if the client has the mtu adjusted.
But when I took the mtu 1492 off of the dialer client, the neighbors don't come backup. Are you sure you getting FULL state connections? ________________________________ I just brought up a a couple of interfaces. No problem -- after I put my MTU (ip mtu 1492) on the correct client interface. dialer vs physical debug was complaining about the smaller mtu on my pppoe server. debug ip ospf adj Yes it is possible to use a pool vs dhcp, and still use OSPF. Mask difference was no problem either. Just a correction of the mtu on the client for my setup. I did this test with area 0 between routers, one loopback in area 1 (IA) and another redistributed (E2). =============SERVER=============== interface FastEthernet0/0 no ip address duplex auto speed auto pppoe enable group DIAL_1 bba-group pppoe DIAL_1 virtual-template 1 interface Virtual-Template1 ip address 192.168.0.1 255.255.255.0 peer default ip address pool DIAL_1 ==============CLIENT=============== interface FastEthernet0/0 no ip address duplex auto speed auto pppoe enable pppoe-client dial-pool-number 1 interface Dialer1 ip address negotiated ip mtu 1492 encapsulation ppp dialer pool 1 BTW, I missed these two earlier posts. Great explanation on the exception to the rule. ;-) --Kenyone Johnson-- One thing comes to mind for me (and this is if no one else has mentioned it, because I didn't read the thread in it's entirety), it mtu. Try to make sure the mtu matches up on the interfaces, because with PPPoE, that dialer interface needs to be decreased, and with ospf the mtu's have to match.... --Mark Abel-- See if this helps. https://learningnetwork.cisco.com/thread/6026 _______________________________________________ Free CCIE R&S, Collaboration, Data Center, Wireless & Security Videos :: iPexpert on YouTube: www.youtube.com/ipexpertinc
