EIGRP LEAKING ROUTES

[ochalmers]

Is it possible to issue eigrp leaking routes on catalyst 6500 running IOS 12.2-33SXI9 on gigabitethernet interfaces? or is there another way to acomplish this?

Regards

What do you mean by "EIGRP leaking routes"?

From one EIGRP domain to another?

Hi Sharifi, i need to publish a more accurate route through a summarization

[Reza Sharifi]

What is the design look like?

What are you trying to accomplish?

I'll check when I get to the office tomorrow, but I'm pretty sure summary leaking should be in SXI9, which is running EIGRP release 5. I actually wrote the stub and summary leaking enhancement several years ago, which should have been well before rel 5. When you do the summary-address interface command do you see a leak-map option?

Hi Donald, this is what i see when i try to issue the command

er-mun(config)#int gigabitEthernet 3/0/0.2

er-mun(config-subif)#$address eigrp 4944 10.168.0.0 255.254.0.0 ?

  <1-255>  Administrative distance

er-mun(config)#int atM 1/1/0.41

er-mun(config-subif)#$address eigrp 4944 10.168.0.0 255.254.0.0 ?

  <1-255>  Administrative distance

It seems not to be available on this type of interfaces.

Sorry about that, but it looks like you're out of luck.  I commited the Stub leaking enhancement first and it made it into SXI.  The summary leaking enhancement was added later and didn't make it into SXI.  IIRC, by the time we got the summary leaking change ready, SXI was closed to new features/featurettes and would only take fixes.  This didn't qualify. I might be wrong on the timing, but I'm certain that the enhancement wasn't added to SXI.

Donald, i try to issue the command on the same switch but using a serial interface and for some reason "i do not know" it's available.

er-mun(config)#int serial 13/0/1

er-mun(config-if)#ip summary-address eigrp 444 10.168.0.0 255.254.0.0 ?

  <1-255>   Administrative distance

  leak-map  Allow dynamic prefixes based on the leak-map

What could it be the reason????

Yep, my bad.  I saw there wasn't a commit to SXI for summary leaking (but there was for stub leaking) and made a bad assumption.  Apparently SXI got the summary leak enhancement through a sync from another branch instead of a direct commit and I didn't look far enough to find it via the sync.    Sorry for the mis-information.

I did, however, find your problem.  There is an outstanding defect that the summary-leak enhancement doesn't work on sub-interfaces (CSCsz90607).  This is undoubtedly what you're hitting.

Again, sorry for the mistake.

Hi Donald, you are absolutely right, i just test on a interface without the sub-interface configuration and it works!!!

Do you know if there is a workaround??? Maybe an IOS upgrade???

Thank you so much!!
