g. Assign the BGP neighbor to an autonomous system in ROUTER-BGP-NEIGHBOR mode.
remote-as as-number
h. Enable the peer session with the BGP neighbor in ROUTER-BGP-NEIGHBOR mode.
no shutdown
i. Return to ROUTER-BGP mode.

For each BGP peer session in the overlay network:
a. Configure the BGP peer using its Loopback IP address on the VTEP in ROUTER-BGP mode.
neighbor loopback-ip-address
b. Assign the BGP neighbor Loopback address to the autonomous system in ROUTER-BGP-NEIGHBOR mode. The neighbor
Loopback IP address is the source interface on the remote VTEP.
remote-as as-number
c. Use the local Loopback address as the source address in BGP packets sent to the neighbor in ROUTER-BGP-NEIGHBOR
mode.
update-source loopback0
d. Send an extended community attribute to the BGP neighbor in ROUTER-BGP-NEIGHBOR mode.
send-community extended
e. Enable the peer session with the BGP neighbor in ROUTER-BGP-NEIGHBOR mode.
no shutdown
f. Configure the L2 VPN EVPN address family for VXLAN host-based routing to the BGP peer in ROUTER-BGP-NEIGHBOR
mode.
address-family l2vpn evpn
g. Enable the exchange of L2VPN EVPN addresses with the BGP peer in ROUTER-BGP-NEIGHBOR mode.
activate
h. Return to ROUTER-BGP mode.
exit
i. Enter IPv4 address-family configuration mode from ROUTER-BGP mode.
address-family ipv4 unicast
j. Disable the exchange of IPv4 addresses with BGP peers in ROUTER-BGP mode.
no activate
k. Return to ROUTER-BGP-NEIGHBOR mode.
exit
l. (Optional) If all the leaf switches are configured in the same ASN:
● On each leaf switch, enter L2VPN EVPN address-family configuration mode from ROUTER-BGP-NEIGHBOR mode.
Activate the exchange of L2VPN EVPN addresses with BGP peers. Configure the switch to accept a route with the
local AS number in updates received from a peer in ROUTER-BGP-NEIGHBOR-AF mode.
