Reg support for VRF configuration in BGP
by Ashvin Lakshmikantha 13 Feb '18

13 Feb '18

Hi all, I am new to the FRR community. I was able to download the software and install it in a VM to play with it. I am currently using the stable 3.0-3 build. My interest is in BGP VPN (RFC 4364). I could not figure out how to configure VPNs and exchange prefixes between two peers. However, there are display commands to display VPN routes. Is BGP VPN configuration supported in the stable 3.0-3 build? If yes, I would appreciate if someone could provide a pointer on configuring it from the vtysh shell. Thanks, Ashvin

VRF Configuration
by Donald Sharp 11 Feb '18

11 Feb '18

All - Since properly configuring a VRF has become a point of contention, I've started a wiki on how to properly configure VRF's so that you can use them properly with FRRouting: https://github.com/FRRouting/frr/wiki/Configuring-a-VRF-to-work-properly-fo… thanks! donald

Experimental OSPF SR
by Donald Sharp 07 Feb '18

07 Feb '18

All - We have added Experimental support of OSPF SR (draft-ietf-ospf-segment-routing-extensions-24). I would like to thanks Olivier for his hard work in getting this work done and Renato taking the time to fully review and test this feature. This feature is available on the master branch. For Instructions on how to use this new feature, please consult doc/OSPF-SR.rst. Thanks! donald

А почему бы не реализовать поддержку sigment routing в BGP?

Static VRF Route Leaking
by Donald Sharp 23 Jan '18

23 Jan '18

All - I'd like to thanks Philippe Guibert, Lou Berger, Renato Westphal and Russ White working with me to get static route leaking into the FRR code base on master. To configure: vrf DONNA ip route 4.3.2.1/32 99.1.2.3 nexthop-vrf EVA ! vrf EVA ip route 9.1.2.3/32 44.3.2.4 nexthop-vrf DONNA ! These two commands create a static route that leaks the nexthops into the appropriate vrf's. At this point in time, BGP has not been modified to take advantage of vrf route leaking in the traditional manner, but the underpinnings in zebra and the zapi protocol are now there. donald

layer-2 vxlan discovery w/ EVPN question
by Henry Snow 20 Jan '18

20 Jan '18

I have a bare metal hosting provider that provides me with layer-3 networking to every server. For some applications, I require a layer-2 network spanning the servers. This network is for the applications running on the server OS, not via VM or container tennants. I've been following this blog post: https://vincent.bernat.im/en/blog/2017-vxlan-bgp-evpn, using frr 3.1dev from git master from several nights ago. I believe I have the route reflector + vteps configured with respect to bgpd as described, but no routes are advertised. I do see bgp neighbors as expected. When I run 'show evpn mac vni 100', I do not see any mac addresses. My suspicion is that it is because I'm not using a bridge, but assigning an IP address directly to the vxlan interface. Looking at the source code (my C is very rusty), it looks like it enumerates all the VNIs, finds the bridges they're slaved to, then enumerates the interfaces on the bridge. I'm looking at this: https://github.com/FRRouting/frr/blob/8eac4812601f069f14fc7950e10904c2ae0ae… Is there a way to configure my interfaces without a bridge (or is this a bad approach)? If a bridge and additional slaved interface is required, any suggestions on how to configure the bridge with no additional tenants on the servers? Additional Thoughts: - using static unicast discovery, vxlan membership across servers works - adding a bridge interface and slaving the vxlan interface + a dummy interface, assigning an ip to the dummy did not seem to work - tried kernel 4.4 from elrepo, (tends to work better from previous docker overlay network experiences) Config: compiled from commit c1240044fbf081bb7407b1449d3954e4b63fec9f on CentOS 7.4, with --enable-cumulus Route Reflector: 10.40.1.131/31 bgpd.conf: router bgp 65000 bgp router-id 10.40.1.131 bgp cluster-id 10.40.1.131 bgp log-neighbor-changes no bgp default ipv4-unicast coalesce-time 1000 neighbor fabric peer-group neighbor fabric remote-as 65000 neighbor fabric update-source 10.40.1.131 neighbor fabric capability extended-nexthop bgp listen range 10.40.1.128/25 peer-group fabric ! address-family l2vpn evpn neighbor fabric activate neighbor fabric route-reflector-client exit-address-family ! layer-2 member server example: 10.40.1.129/31 bgpd.conf: router bgp 65000 bgp router-id 10.40.1.129 no bgp default ipv4-unicast coalesce-time 1000 neighbor fabric peer-group neighbor fabric remote-as 65000 neighbor fabric capability extended-nexthop neighbor 10.40.1.131 peer-group fabric ! address-family l2vpn evpn neighbor fabric activate advertise-all-vni exit-address-family ! vxlan configured with: # ip link vxlan100 type vxlan id 100 local 10.40.1.129 port 4789 nolearning # ip link set up dev vxlan100 # ip addr add 172.31.254.2/24 dev vxlan100 Thanks for any suggestions (or course corrections, as this is new to me)! -- Henry Snow | Director, Site Reliability Engineering eXelate, a Nielsen company <http://exelate.com/> E: henry.snow(a)nielsen.com | M: 347.366.2700 675 6th Ave, 3rd Floor, New York, NY 10010

New EVPN Code in Master
by Donald Sharp 18 Jan '18

18 Jan '18

All - EVPN control plane in FRR is now enhanced so that it supports both asymmetric and symmetric routing models. Prefix-based routing is also supported using EVPN type-5 routes. Also, with all routing models, L3 multi-tenancy is inherently supported I'd like to thank Mitesh for his hard work getting this done! thanks! donald
