Verify that a Tier-0 Router Has Learned Routes from a Tier-1 Router

When a tier-1 logical router advertises routes to a tier-0 logical router, the routes are listed in the tier-0 router's routing table as NSX-T Data Center static routes.

Procedure

On the NSX Edge, run the get logical-routers command to find the VRF number of the tier-0 service router.

nsx-edge-1> get logical-routers
Logical Router
UUID        : 736a80e3-23f6-5a2d-81d6-bbefb2786666
vrf         : 0
type        : TUNNEL

Logical Router
UUID        : 421a2d0d-f423-46f1-93a1-2f9e366176c8
vrf         : 5
type        : SERVICE_ROUTER_TIER0

Logical Router
UUID        : f3ce9d7d-7123-47d6-aba6-45cf1388ca7b
vrf         : 6
type        : DISTRIBUTED_ROUTER

Logical Router
UUID        : c8e64eff-02b2-4462-94ff-89f3788f1a61
vrf         : 7
type        : SERVICE_ROUTER_TIER1

Logical Router
UUID        : fb6c3f1f-599f-4421-af8a-99692dff3dd4
vrf         : 8
type        : DISTRIBUTED_ROUTER

Run the vrf <number> command to enter the tier-0 service router context.
```
nsx-edge-1> vrf 5
nsx-edge1(tier0_sr)> 
```

On the tier-0 service router, run the get route command and make sure the expected routes appear in the routing table.

Notice that the NSX-T Data Center static routes (ns) are learned by the tier-0 router because the tier-1 router is advertising routes.

nsx-edge1(tier0_sr)> get route

Flags: c - connected, s - static, b - BGP, ns - nsx_static
nc - nsx_connected, rl - router_link, t0n: Tier0-NAT, t1n: Tier1-NAT

Total number of routes: 7
