After a router reboot the L3 network via it converges before the L2 network. This is because MLAG intentionally holds down bridge-access and vxlan-network ports for some time (MLAG init-delay) to prevent traffic from switching to a router that is not fully ready. This also means that routes (from vrf-peering sessions) that qualify for evpn type-5 advertisments are available long before the L3-VNI is available for that tenant VRF. In these windows bgpd was adding these evpn-type-5 routes with a L3-VNI of 0 (which was not fixed up after the L3-VNI became available) - BGP routing table entry for 100.0.0.1:2:[5]:[0]:[0]:[32]:[200.1.1.1] Paths: (1 available, best #1) Advertised to non peer-group peers: MSP1(uplink-1) MSP2(uplink-2) Route [5]:[0]:[0]:[32]:[200.1.1.1] VNI 0 >>>>>>>> 65001 65535 36.0.0.9 from 0.0.0.0 (27.0.0.9) Origin incomplete, metric 0, valid, sourced, local, bestpath-from-AS 65001, best Extended Community: ET:8 RT:5544:4001 Rmac:44:38:39:ff:ff:01 AddPath ID: RX 0, TX 327 Last update: Wed Feb 27 18:37:10 2019 Fix is to defer creating type-5 routes till the L3-VNI is available for that tenant VRF (this was already being done for most cases; fixup takes care of some that missed the check).
