[FROG] BGP L3VPN support

[Heidi net]

Thanks for your replies, I actually went through the document/examples for FRR 5.0, but wondering if I could do L3VPN on 4.0, without VRF leaking.

In order to do that, I need to attach RD/RT to each VRF, so looking for configuration to configure RD/RT in FRR4.0.


thanks
