Multiprotocol Border Gateway Protocol (MBGP) Support for VXLAN

The BGP is a general purpose routing protocol that runs over TCP. Routes can be carried on different address family (afi) and sub-address family (safi) combinations as specified in the Multiprotocol BGP (MBGP) extensions.

The BGP implementation for ExtremeXOS supports carrying VXLAN VNI and LTEP combinations as MBGP routes using a proprietary afi/safi combination. Even though supported LTEPs are IPv4, the VXLAN routes can be carried over IPv6 peering sessions.

To enable or disable IPv4 VXLAN capability on a per peer basis, use the commands:

enable bgp neighbor [all |remoteaddr] capability [ipv4-unicast | ipv4-multicast | ipv6-unicast | ipv6-multicast | vpnv4 | route-refresh | ipv4-vxlan | l2vpn-evpn]

disable bgp neighbor [all | remoteaddr] capability [ipv4-unicast | ipv4-multicast | ipv6-unicast | ipv6-multicast | vpnv4 | route-refresh | ipv4-vxlan | l2vpn-evpn]

Limitations

• The ability to carry VXLAN routes cannot be enabled on a per peer group basis.
• BGP graceful restart is not supported on the MBGP/VXLAN feature.
