I was trying to setup a VRF to isolate some routes from the global VRF, but it seems like traffic got blackhole after applying the VRF. I can't not ping 10.10.10.1 from the ubuntu server. Can you help me with this issue? The environment is as below:

Ubuntu server has a VLAN 10 with ip 10.10.10.2
MLXe-8000 has a ve 10 with IP 10.10.10.1 , ve 10 is assigned to the VRF
VRF configuration in the router as following:

vrf test

rd 111:222

route-target export 111:222

route-target import 111:222

address-family ipv4

import routes vrf default-vrf route-map test-vhf

exit-address-family

exit-vrf

interface ve 10

port-name test_out_10

vrf forwarding test

ip address 10.10.10.1/30

I am fighting the same thing right now. According to the Knowledgeable article, if the cam profile used is ipv4-ipv6, it does not support none default vrf. See here:

Myself, I need VRF working and 2M routes. I got the BR-MLX-100Gx2-CFP2 card which I have right now with "amod" running to support 2M routes and ipv4-ipv6-2, so VRF is not working. Thinking about to change it to default so VRF works, but I am unsure how many max ipv4 routes I can have in fib with default + amod.
