Issue/Introduction
After performing a failover from edge 1 to edge 2, traffic will not be routable, and will lose connection to the network
Environment
VMware NSX
Cause
Due to misconfiguration at the Physical level and virtual level, the Traffic was being dropped at the gateway
Resolution
Troubleshooting step:
- SSH to both edges and confirm there is connectivity between both edges by doing a ping
Ping < destination ip>
if we don't see a successful ping
Check the edge network configuration with the following command:
get interface <eth>
You should see a similar output
Interface: eth0
IPv4:
Address:00.000.00.0
Default gateway: 1.234.23.444
Broadcast address: 0.00.00.00
IPv6: not configured
MAC address:m1.1.mn.mm.m
make sure to run the same command on both edges
If you see the default gateway value being the same on both edges, then let it as it's but if you see it matching value other than the default gateway, then we have a duplicated ip that need to be changed
Set interface <eth> <bad ip> gateway <good ip >
