Router A configuration
1. Configure recommended RA timers globally for fast convergence in CONFIGURATION mode.
OS10-A(config)# ipv6 nd min-ra-interval 3
OS10-A(config)# ipv6 nd max-ra-interval 4
2. Make the required interfaces in CONFIGURATION mode and convert them to Layer 3 routing interfaces.
OS10-A(config)# interface range ethernet 1/1/1-1/1/4
OS10-A(conf-range-eth1/1/1-1/1/4)# no shutdown
OS10-A(conf-range-eth1/1/1-1/1/4)# no switchport
3. Enable RA transmission on all the interfaces in the range in INTERFACE mode.
OS10-A(conf-range-eth1/1/1-1/1/4)# ipv6 nd send-ra
4. Configure the interfaces as BGP auto-unnumbered interfaces in INTERFACE mode.
OS10-A(conf-range-eth1/1/1-1/1/4)# ipv6 bgp unnumbered ebgp-template
5. Create BGP instance in CONFIGURATION mode.
OS10-A(config)# router bgp 100
6. Create a template and assign necessary parameters in ROUTER-BGP mode.
OS10-A(config-router-bgp-100)# template ext-bgp
OS10-A(config-router-template)# timers 120 360
7. Enable the BGP auto-unnumbered neighbor feature in ROUTER-BGP mode.
OS10-A(config-router-bgp-100)# neighbor unnumbered-auto
OS10-A(config-router-neighbor)# no shutdown
8. Configure the peer group template that the neighbors use to inherit peer-group configuration in ROUTER-NEIGHBOR mode.
This template is applied only to the auto-unnumbered interfaces configured with the ipv6 bgp unnumbered command.
OS10-A(config-router-neighbor)# inherit ebgp-template ext-bgp
9. Enable IPv6 address family to advertise IPv6 routes in ROUTER-NEIGHBOR mode.
OS10-A(config-router-neighbor)# address-family ipv6 unicast
OS10-A(config-router-bgp-neighbor-af)# activate
10. Enables EVPN address family to advertise EVPN routes in ROUTER-NEIGHBOR mode.
OS10-A(config-router-neighbor)# address-family l2vpn evpn
OS10-A(config-router-bgp-neighbor-af)# activate
Router B configuration
1. Configure recommended RA timers globally for fast convergence in CONFIGURATION mode.
OS10-B(config)# ipv6 nd min-ra-interval 3
OS10-B(config)# ipv6 nd max-ra-interval 4
2. Make the required interfaces in CONFIGURATION mode and convert them to Layer 3 routing interfaces.
OS10-B(config)# interface range ethernet 1/1/1-1/1/8
OS10-B(conf-range-eth1/1/1-1/1/8)# no shutdown
OS10-B(conf-range-eth1/1/1-1/1/8)# no switchport
