L3EVPN Lab Host1 and Leaf1 connections failure #158

Closed edgarshine closed 3 years ago

edgarshine commented 4 years ago

Describe the bug Not connection between Host1 and Leaf1 on network 172.16.115.0/24 Initial findings points to Leaf1 provisioning inconsistency.

To Reproduce Found in step 7-2 first test trail. Apparently this happens if you go straight to L3EVPN lab after a fresh topology start. Doing a reset in the Jumphost and applying l3evpn profile again fixed the lab.

Expected behavior Successful ping in step 7-2 L3EVPN Lab doc
