RE: OSPF Question / Problem [7:60485]
I must have come across a bug or something. I have one router using IOS 11.0(22a) and the other router is using IOS 11.3(9) The issue now, is that for some reason, via OSPF, one router will advertise its interfaces that are part of another area, whilst the other router will not. Yes I have made sure the interface is up. Does any one know of a problem of OSPF across older IOS ? Ps: when I try this on another router, such as 2 routers using IOS 11.3(9) this works no problem) John -Original Message- From: John Brandis [mailto:[EMAIL PROTECTED]] Sent: Tuesday, 7 January 2003 4:17 PM To: [EMAIL PROTECTED] Subject: RE: OSPF Question / Problem [7:60485] Resolved, thanks Chuck However, this is how I fixed it.

Re: OSPF Question / Problem [7:60485]
John, There are 5 ospf network types: 1. point-to-point - such as T-1, valid neighbors on each end will always become adjacent. 2. Broadcast - such as ethernet, token ring, and FDDI. Broadcast network are capable of connecting more than 2 devices. OSPF routers on the broadcast network will elect a DR and BDR. 3. NBMA (non-broadcast multi-access) such as X.25, frame-relay, and ATM. Capable of connecting more than 2 routers but no broadcast capability. Extra configuration must be done for routers on these network to acquire their neighbors. 4. Point-to-multipoint - Special configuration of NBMA networks. NBMA networks are treated as a collection of point-to-point links. Router on these networks do not elect a DR and BD and because their network is seen as point-to-point links, packets are unicast. 5. Virtual Links - Interpreted by the router as unnumbered point-to-point network. All that being said, PPP over HDLC the default network type is point-to-point as listed in #1 above. When I can't seem to get OSPF working across circuits I look at things like, network type, ensure my subnet masks are correct in the network statement. Also turns on debug ip ospf adj, that will tell you where the adjacency process is failing. Good Luck Debbie On Tue, 7 Jan 2003, John Brandis wrote: > G'Day all > > 1).

I while back I had heard some talk about issues with using this form in some IOS versions. I don't recall the talk, and I assume recent IOS versions corrected whatever the problem was. > > Why would not just listing them as the networks bound by the 30 bit mask not > work it does. the only problem I can think of is ot having the mask correct. network 192.168.1.4 0.0.0.3 area X puts only dot 5 and dot 6 into the process network 192.168.1.8 0.0.0.7 puts dot 9 through dot 14 into the process so if I had several loopbacks, each with a /32 mask, all of those in the range above would be placed into the ospf process. network 192.168.1.0 0.0.0.255 puts all of the above into the process, plus a bunch more. so if I had 20 different serial links, each numbered with 192.168.1.x/30, the above statement puts them all into the ospf process. > > Thanks for your time dude no problem. all your interface are belong to ospf. make your time. > > John > Sydney Australia > > Ps: sorry for the disclaimer size, its huge > > > -Original Message- > From: John Brandis [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, 7 January 2003 3:29 PM > To: [EMAIL PROTECTED] > Subject: OSPF Question / Problem [7:60485] > > > G'Day all > > 1).

On an ethernet or a token ring, for example, there is only one type possible - broadcast. on a serial link, there is only one type posssible - point-to-point ( OK, on these two maybe it's possible to manually change the type, but why would you? ) on frame relay, it gets complicated. the physical interace defaults to non-broadcast ( NMBA ) on a subinterface, it depends on whether the subinterface is multipoint or point-to-point HTH > > John > Sydney Australia > > > > ** > > visit http://www.solution6.com > > UK Customers - http://www.solution6.co.uk > > ** > > The Solution 6 Head Office and Branch in Sydney is moving premises. > > From Monday 25th November our Head Office and NSW Branch will be located at: > > Level 14, 383 Kent Street, Sydney NSW 2000. > > General Phone: 61 2 9278 0666 > > General Fax: 61 2 9278 0555 > > ** > > This email message (and attachments) may contain information that is > confidential to Solution 6.
