NSX-t 2.4
Created 3 segmets WEB APP DB and connected to T1 gateway (composed by a DR SR).
East west routing is working
Created a T0 gatwìeay with an external interface with IP 172.16.0.99.
T1 and T0 are linked
T1 is set to advertise all Connected Segments & Service Ports
T0 is set to re-distribute all Connected T0 Segments and T1 connected subnets
From a VM connected to a segment I'm not able to ping the T0 uplink address 172.16.0.99.
T1 Dist router has a default route 0.0.0.0/0 169.254.0.2(T1 Service router)
T1 Service router has a default route 0.0.0.0/0 100.64.144.0(T0 Dist Router)
T0 Dist router has a default route 0.0.0.0/0 169.254.0.2(t0 Service router)
T0 Service router owns the IP 172.16.0.99.
How to troubleshoot this problem?
Solved.
The EDGE NODE VM was hosted by an ESXi preaped as transport node. In this case, the 2 TEPS must be in different subnets and my TEPS was in the same subnet
I am having the same issue E-W works fine as long as they are Geneve backed but if I connect a VLAN backed segment to T1 I can't ping it from a Geneve backed segment.
I have my provider management network as a downlink on T0 and it works fine for N-S traffic on a VLAN backed segment.
I have all the Route-Redistribute and Advertisement configured, static route on T0 and SNAT on T0.
Well interesting, I can ping from T0 VLAN backed segments into the T1 connected Geneve segments.
I'm guessing this is a routing issue as I want T0 VLAN backed segments to reach T1 Geneve segments and I want T1 Geneve segments to reach T0 VLAN backed segments and the WAN but not T1 to T1 Geneve segments (no firewall rules in place for that yet though).
Getting a grip on the differences from NSX-v to NSX-T has not been easy!
I think I tracked down my issue, I had a static route defined for a VLAN that was using the L3 switch for routing and then I moved it to Tier-1 and removed routing from the VLAN but missed the static route defined at Tier-0.
Might comb over those settings and make sure you aren't overlapping subnets.
