11 | Following tests are covered to test BGP Multi-VRF Dynamic Route Leaking: | |
12 | 1. Verify recursive import among Tenant VRFs. | |
13 | 2. Verify that dynamic import works fine between two different Tenant VRFs. | |
14 | When next-hop IPs are same across all VRFs. | |
15 | When next-hop IPs are different across all VRFs. | |
16 | 3. Verify that with multiple tenant VRFs, dynamic import works fine between | |
17 | Tenant VRFs to default VRF. | |
18 | When next-hop IPs and prefixes are same across all VRFs. | |
