EVPN with iBGP Configuration Example

Configuration Notes

iBGP auto-RT capability is used.

Note

If 4 byte AS numbers are used, RTs should be manually created.

MLAG peers share the same LTEP IP, but use different BGP router IDs.
OSPF adjacency between Leafs and Spines, between MLAG peers. PTP link type is used.
OSPF routes are exported to BGP on Spine 1.
On MLAG peers OSPF router IDs should be different (manually configured).
Static LACP MAC is configured on MLAG peers.
BGP maximum paths is set to 2 for this topology and IP route sharing is enabled.
ARP suppression is enabled on tenant VLANs.
Spines are configured as RR.

Note

On SLX and other platforms “retain route-targets” should be enabled on spine/transit L3 nodes.ExtremeXOS by default retains all RTs and does not have a command to tun it off.
ExtremeXOS does not support multi-hop BFD currently—under certain conditions convergence might take longer time.
