EIGRP Query Domain or Flooding Domain.

llllvllll

Here R1 & R4 are in Same Eigrp asn that is 100.
(R1 & R6 ) + (R1 & R5 ) are also in same EIGRP asn that is 100.

now interface connecting R1 & R2 are in EIGRP asn 200.

Note:- There is no redistribution in R1 between EIGRP 100 & EIGRP 200.

Suppose R4's interface goes down. Now R1 will send Query messages to its neighbor R6 & R5.(assuming R1 don't have a FS)

Now my question is will R1 send a query Message to R2 ? (its in different EIGRP process).

If Not can we say Different EIGRP Proccess can also reduce Query time and help in fast convergence? (like summarization).

MrXpert

using debug eigrp packet terse command will show you the results.

I'd say that R1 would not send queries to R2. If you redistribute between AS100 and AS200 then it will query R2 for the lost route.

I'm with MrXpert, R1 would only query those neighbors in the same ASN. If your goal is to just reduce query time look into creating stubs networks/summary routes or changing the SIA timer.

Hmm thanks everyone.
