-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Daniel Ma Sent: Tuesday, June 06, 2000 8:51 PM To: [EMAIL PROTECTED] Subject:Re: OSPF configuration - Please help In router A, I think you could not put the mask as 0.0.0.0, because if so the area only include one ip address. CL: gentle correction. In OSPF, the network statement places interfaces, not addresses, into the OSPF process. This is not well explained in many of the study materials, and many examples appear to place subnets into OSPF. Thus, if one were to use the network statement 10.1.1.1 0.0.0.0 area 0, this would place only the interface with that number into OSPF. Functionally speaking, one could say network 10.1.1.1 0.255.255.255 and have the same result. I have done a number of experiments along this line, and verified that so long as the network statement matches an interface address in one way or another, it makes no difference how you state it. OSPF functions correctly, and packets get router correctly. I don't know, but I believe that the Cisco IOS OSPF process gathers subnet and mask information directly from the interface configuration. This can lead to some interesting and fun ways of doing things. For example, suppose you had a super routers with 200 interfaces and subinterfaces, and ever one of those interfaces was numbered in such a way that the third octet was 42. .e. 192.168.42.67, 10.99.42.240, 172.23.42.1, you get the idea. You can put each and every one of those interfaces into the OSPF process with a single command. - network 0.0.42.0 255.255.0.255 area 0 ( assuming you want them all in area 0 ) Not earth shaking information. Just something to help understand how things work. Another thing is, have u try show interface and make sure the Serial port is up?

Re: OSPF configuration - Please help
Hi, Router B is misconfigured.. The ospf process should contain.. 192.1.1.0 255.255.255.0 area 0 I would put the loopback addresses in as well and not this network 0.0.0.0 255.255.255.255 <-- this does not even have an area assigned..

Re: OSPF configuration - Please help
Are you able to ping the other router? Do you see it with 'sh cdp nei'? Also, you should do 'shut' then 'no shut'. The other way around shuts down the interfaces (the way you said below). Also, on Router B, I see no indication of an area statement. IE: network 192.1.1.0 0.0.0.255 area 0. There is a network statement under router ospf, but I am not familiar enough to know the effects of putting 0.0.0.0 0.0.0.0 in that statement. My understanding is that you must give it an area (although if you don't, it may default to area 0).

Re: OSPF configuration - Please help
Your OSPF config on router B is wrong : You did : router ospf 64 network 0.0.0.0 255.255.255.255 Or you should have at least something like this : router ospf 64 network 192.1.1.2 0.0.0.0 area 0 AR- On Tue, 6 Jun 2000, Billy Monroe wrote: > Hello: > > I have two 2503 and I am following Hutnik's to configure OSPF. > I connected RouterA, s0 (DCE) to RouterB, s0(DTE). > > When I enter #show ip ospf int I see the following: > ... > Transmit Delay is 1 sec, State DOWN > Hello due in... > ... > > > The State should be "POINT_TO_POINT". > The routers don't see each other.
