Hello,
Hope some can help and identify an issue I am facing. Below is my lab topology in GNS3, using nxsosv-9k-7.0.3.16.2 image.
ASW has links to NXS1 and NXS2 in a port channel. Everything works fine in the normal scenario, I can ping both NXS and HSRP. When I fail one of the link, from NXS1 to ASW, I cannot ping NXS2 or the HSRP IP but odd, I can ping NXS1. In the failure scenario, the only path for ASW is via NXS2, so unsure why I can't ping it but can ping NXS1 over vpc peer link.
Before the failure, MAC address table of ASW shows path for NXS1 & HSRP via Gi0/1. After the failure, it correctly updates the MAC table to Gi0/0 for all three IPs. So unsure what the issue and what I am doing wrong.
Any help is highly appreciated, all configs and outputs attached. Thanks in advance.
