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 Congure 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 used as 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 extend
e Enable the peer session with the BGP neighbor in ROUTER-BGP-NEIGHBOR mode.
no shutdown
f Congure 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.

h Return to ROUTER-BGP mode.

i Enter IPv4 address-family conguration mode from ROUTER-BGP mode.
address-family ipv4 unicast
j Disable the exchange of IPv4 addresses with BGP peers in ROUTER-BGP mode.

2 Congure EVPN.
An EVPN instance (EVI) spans across the VTEPs that participate in the EVPN. In OS10, you can congure an EVI in auto-EVI or
manual conguration mode.
• Auto-EVI mode
1 Enable the EVPN control plane in CONFIGURATION mode.
evpn
2 Enable auto-EVI creation for overlay virtual networks in EVPN mode. Auto-EVI creation is supported only if BGP EVPN is
used with 2-byte AS numbers and if at least one BGP instance is enabled with the EVPN address family. No further manual
conguration is allowed in auto-EVI mode.
auto-evi
• Manual EVI conguration mode
1 Enable the EVPN control plane in CONFIGURATION mode.
evpn
2 Manually create an EVPN instance in EVPN mode (1 to 65535).
evi id
3 Congure the Route Distinguisher in EVPN EVI mode.
rd {A.B.C.D:[1-65535] | auto}
Where:
– rd A.B.C.D:[1-65535] congures the Route Distinguisher with a 4-octet IPv4 address followed by a 2-octet-
number.
