EIGRP on Cisco ASA - REQUEUEFAILURE

[mthomati]

I encountered the following error when running a routing related question layer3Edges against a Cisco ASA config located in my snapshot.

status: REQUEUEFAILURE
.... 2024-02-22 11:22:44.684000-06:00 Couldn't requeue after unblocking.
Cannot queue dataplane dependent work for fe0edfb9-c7b9-450b-a02a-ce44c1e6038d: Status is DATAPLANING_FAIL but no incomplete dataplaning work exists.

However, when I remove the EIGRP configuration from the ASA:

router eigrp 90

 redistribute static metric 100000 100 1 255 1500 route-map STATIC-2-EIGRP

Batfish is able to parse the config for any routing related questions such as layer3Edges. The issue is with that EIGRP config and Batfish unable to parse it correctly. Please help?

[dhalperi]

I wasn't able to run the example code you provided. Can you please use the bug report issue template?

[dhalperi]

The other thing you might try for debugging dataplane issues is running bf.generate_dataplane() separately and getting back info in the stack trace there.

[mthomati]

Hi, I can post a bug report if that is better to put this output, below is the output generated from bf_generate_dataplane:

Yeah I think we need a runnable repro. The stack trace helps, but it makes it look like interface BW is being treated as zero. need more data for that.
