Configuring BGP EVPN VXLANv6 Migration from VXLANv4 to VXLANv6 Step 1 • Configure IPv4/IPv6 Loopback interface. VTEP(config)#interface Loopback1 VTEP(config-if)# ipv6 address ABCD:1::2/128 VTEP(config-if)# ipv6 ospf 1 area 0 • Enable Dual Stack. VTEP(config)# interface nve1 VTEP(config-if)# vxlan encapsulation dual-stack prefer-ipv6 • For unicast traffic and BUM traffic using ingress replication, the dual stack VTEP communicates with other IPv4 VTEPs using VXLANv4 and with other dual stack VTEPs using VXLANv6. Configure static multicast replication for L2VNI.
VTEP(config-if)# member vni 20011 mcast-group 239.2.1.11 FF0E::11 Step 2 • This step is only needed for BUM traffic using Multicast Replication. • After all the VTEPs are dual stack-capable, underlay multicast switches to IPv6 Multicast. VTEP(config)# interface nve1 VTEP(config-if)# vxlan encapsulation dual-stack prefer-ipv6 underlay-mcast ipv6 Configuring BGP EVPN VXLANv6 7
