From bee1bcfd015a18a00064722f6388db14f9e0b5c7 Mon Sep 17 00:00:00 2001 From: Donald Sharp Date: Fri, 25 Oct 2024 11:28:45 -0400 Subject: [PATCH] tests: Add a topology that supports a large number of ecmp Add a basic topology that allows the testing of BGP and zebra at scale. I built this to help me find and fix problems with a large number of bgp peers. Since I plan to keep using this and as I understand it there are future plans to take this higher, I would like to add this as a test that people can invoke with this command: sudo -E python3 -m pytest -s -vv --topology-only Signed-off-by: Donald Sharp --- tests/topotests/high_ecmp/r1/frr.conf | 267 ++++++++++++++++++++ tests/topotests/high_ecmp/r2/frr.conf | 267 ++++++++++++++++++++
