Re: OSPF demand Circuit [7:20228]
Lance, You should be able to use this command on typically any router that at mimimum has an "aux" port. A quick look on CCO for the command "ip ospf demand-circuit" showed that the command was supported from version 11.2. HTH Nigel Chuck.. maybe when you talk to your ISP the word "rebate" should make it's way into the conversation. ;-> - Original Message - From: "Chuck Larrieu" To: Sent: Tuesday, September 18, 2001 10:35 PM Subject: RE: OSPF demand Circuit [7:20228] > I don't know the answer, so I will ask: > > isn't demand circuit a part of the OSPF specification, per RFC 1793?

RE: OSPF demand Circuit [7:20228]
I don't know the answer, so I will ask: isn't demand circuit a part of the OSPF specification, per RFC 1793? ( and please don't rag on me if I misremembered the RFC #.

Re: OSPF demand Circuit [7:20228]
"show ip ospf database router", look at LSAs without DC in options field.

Re: OSPF demand Circuit [7:20228]
Lance, DNA LSAs are not allowed because router received LSAs (ten different LSAa) without DC bit set in options field from other routers in the area. That means that there are routers in the area which doesn't support demand circuit. As you remember, in order to support DNAs, all routers in the area must support it, which is not the case in your network.
