EVPN VxLAN 中的路由条目是否可以在不同的 VRF 之间共享？

Question

When I built the EVPN VxLAN simulation environment in GNS3, I found that the learned overlay routing entries and underlay routing entries are as follows for SW-1:

Test TOPO

SW-1# show ip route 
Codes:  K - kernel route, C - connected, S - static, B - BGP, O - OSPF
        > - selected route, * - FIB route, q - queued route, r - rejected route, # - not installed in hardware
       Destination                  Gateway                                                Dist/Metric   Uptime      
-------------------------------------------------------------------------------------------------------------------
 C>*   1.1.1.1/32                   Direct                        Loopback0                0/0           00:10:24    
 B>*   2.2.2.2/32                   via 10.1.0.5                  Ethernet8                200/0         00:10:01    
 C>*   10.1.0.4/31                  Direct                        Ethernet8                0/0           00:10:14    
SW-1# 
SW-1# show ip route vrf Vrf01
Codes:  K - kernel route, C - connected, S - static, B - BGP, O - OSPF
        > - selected route, * - FIB route, q - queued route, r - rejected route, # - not installed in hardware
       Destination                  Gateway                                                Dist/Metric   Uptime      
-------------------------------------------------------------------------------------------------------------------
 C>*   192.168.1.0/24               Direct                        Vlan10                   0/0           00:10:05    
 B>*   192.168.2.0/24               via 2.2.2.2                   Vlan30                   200/0         00:10:01 

So can routes between different VRFs be shared?(192.168.2.0/24 -> 2.2.2.2/32)But what I know is that the routing entries for VRF are independent and can not be shared between different VRFs.

Is recursive routing lookup across VRFs legal in this case and how to explain it?

Answer 1

No, VRFs, by definition, are independent, so recursive look ups between them should not possible.
