The thread was originally about the non-NSSA area. That's what I was answering about. In a case of the NSSA area, behavior is slightly different. NSSA ASBR will set FA as the IP field to one of its own IP addresses advertised in OSPF (preference given to Loopback). When the translating ABR creates Type 5 LSA, this information will be preserved, allowing fo the optimal routing to the ASBR. -- Marko Milivojevic - CCIE #18427 (SP R&S) Senior CCIE Instructor / Managing Partner - IPexpert On Tue, Jun 18, 2013 at 10:55 PM, Elie Raad <[email protected]> wrote: > I mean in scenario where we have 2 Exits to O E1/E2 routes , OSPF will > choose to Replace the Advertising Router Attribute to the highest Router-id > Value between Both . in that case OSPF will route toward the one that is > matched inside the Advertising router value, this can cause sometimes > sub-optimal routing issue. > If the Forwarding Address value is set than OSPF will route toward the Fa > address field regardless of the one who did the T 7/5 Translation ensuring > Optimal path selection. > > what if this same route has been advertised but now with the Advertising > router field set and the Fa field Set. and there is no Type 7/5 Translation > since we Satisfied the below conditions for setting the FA to non-zero. the > question is what will OSPF choose as a next hope to get this route > installated in the RIB? > > > > > Regards, > > *Elie Raad | Network and Systems Administrator* > *American University of Science and Technology* > [email protected] | Office: +961-1-218716 Ext: 396 > Office Hours: Mon- Fri 9:00 am-16:00 pm UTC+02:00 > ------------------------------ > *From:* Marko Milivojevic [[email protected]] > *Sent:* Tuesday, June 18, 2013 11:27 PM > *To:* Elie Raad > *Cc:* Saleh Batouq; OSL Routing and Switching > > *Subject:* Re: [OSL | CCIE_RS] OSPF Q > > What would OSPF use as next-hop where? > > -- > Marko Milivojevic - CCIE #18427 (SP R&S) > Senior CCIE Instructor / Managing Partner - IPexpert > > > On Tue, Jun 18, 2013 at 11:09 AM, Elie Raad <[email protected]> wrote: > >> What will ospf use as a next hop , the advertising router ip address or >> the fa address >> >> Ignore any typos, sent from mobile device. >> >> On Jun 18, 2013, at 19:17, "Marko Milivojevic" <[email protected]> >> wrote: >> >> >> Yes it is :-) >> >> On an ASBR that redistributes the route: >> >> 1) next-hop must be known by OSPF (enabled on the interface, or a more >> specific OSPF route to it) >> 2) exit interface for the next-hop must not be passive >> 3) exit interface must be broadcast or non-broadcast >> >> If those are satisfied, redistributed route will have non-zero FA and >> FA will be the next-hop of the redistributed route. >> >> -- >> Marko Milivojevic - CCIE #18427 (SP R&S) >> Senior CCIE Instructor / Managing Partner - IPexpert >> >> >> On Mon, Jun 17, 2013 at 11:13 PM, Saleh Batouq <[email protected]>wrote: >> >>> I would also like to know!!! >>> >>> Best Regards, >>> >>> Saleh >>> >>> On Tue, Jun 18, 2013 at 9:22 AM, Elie Raad <[email protected]> wrote: >>> >>> > Hi Guys , >>> > >>> > is it possible to set the FA Address to non-zero for an O E1/E2 route? >>> > >>> > >>> > >>> > _______________________________________________ >>> > For more information regarding industry leading CCIE Lab training, >>> please >>> > visit www.ipexpert.com >>> > >>> > Are you a CCNP or CCIE and looking for a job?

I labbed this up quick (since I haven't set up LDP in months!) and I happened to have a tunnel interface on the test router that I was using which is what LDP tried to initiate the LDP session from. I could resolve that by adding all interfaces to a dynamic routing protocol like OSPF, or specifying the LDP router-id to be an interface that I had reachability between, or by forcing the MPLS connection to use the interface IPs with: int fa0/0 mpls ldp discovery transport-address interface Check 'show mpls ldp discovery' to see what address is being used for the LDP sessions and see if it's reachable. Really, you want to set the LDP router-id to something reliable like a loopback, and make sure you have /32 routes between those LDP RIDs. IIRC, without that, you may get LDP up but you'll have other various issues.
