WebIn symmetric IRB deployment, IVRL is typically configured at the border VTEPs. At the border VTEP, host routes (published by remote VTEPS via route type-2) are installed. Similarly, the EVPN type-5 prefixes advertised by other VTEPs get installed as prefix-routes (for example, a /24 prefix for IPv4 overlay network). WebIRB is configured whenever EVPN-enabled VLANs in a VRF contain IPv4 or IPv6 addresses: Asymmetric IRB requires no extra parameters (see Asymmetric IRB section for more details) Symmetric IRB used with VXLAN transport needs a transit VNI that has to be set with the evpn.transit_vni parameter.

Leaf switches in a VXLAN network can function as both … WebWith the symmetric IRB routing model, the VTEPs do routing and bridging on both the ingress and egress sides of the VXLAN tunnel. As a result, VTEPs can do inter-subnet routing for the same tenant virtual routing and forwarding (VRF) instance with the same …

WebAsymmetric IRB. This is a basic mode of operation EVPN L3 using IRB interfaces. The term ‟asymmetric” refers to how there are more lookups performed at the ingress leaf than at the egress leaf (as opposed to ‟symmetric”, which implies the same number of lookups at ingress and egress).
