Hi Lou, Donald,

At first glance, the syntax proposed in [1] looks good.

Does that mean that VRF configured under BGP node ( vpn-policy or vrf-policy) will be automatically "connected" to ZEBRA VRF ?

Maybe an explicit additional command would make that relationship possible?

Hi Donald, Lou,

I could not attend the meeting.
Are there any notes, or presentation that could explain what will be the strategy with BGP ?

We're headed towards supporting VRF-lite route leaking and L3VPN over MPLS, with both using common RT and BGP VPN constructs. Donald taking the lead on the zebra additions and Paul Z doing the bgp code changes. Vivek is also looking at cli and will propose a revised syntax. The syntax Paul is currently looking towards can be found at the top of [1], but again this is not finalized.

On a separate work, I came to face the issue where I need to redirect flow to a specific VRF, based on route target input.
I was wondering if that work was crossing or not.

I suspect yes. How is the flow encapsulated over the core?

I am in progress of having FlowSpec Client into FRR. More information

Flowspec basically applies some kind of policy ( some rules describe which traffic, and what to do with) based on BGP Flowspec infomation.

My setup is not finalised yet, I have the main traffic that is not encapsulated.
For security reasons, BGP receives a BGP Flowspec message, including an extended community that asks to redirect that traffic to a VRF.

I expect that BGP identifies the ZEBRA VRF, based on the incoming extended community ( made with Route Target).

I also expect that the RD and RT concepts do not cross BGP/ZEBRA borderline. I expect that the matchine VRF_ID will be contained in the ZAPI message.

Thanks,

Philippe

All -

During discussions this morning w/ Lou we discovered that we are both
working towards a BGP solution for Route Leaking. We have enough
differences between our approaches that we need to spend some time
consolidating our approach. The current plan is to have the meeting
at 3:30 EDT this Friday Jan 19. If you would like to attend please
let me know and I will put you on the invite for it.
