EVPN-VXLAN Signaling

Select the Exhibit button.

Question Image

An ERB overlay topology with an EBGP underlay has been implemented. VXLAN tunnels are forming with the spine device acting as the VTEP.

With reference to the exhibit, which change must be made to the group overlay configuration?

  • A The multipath disable parameter must be added.
  • B The multihop no-nexthop-change parameter must be added.
  • C The cluster 10.1.1.1 parameter must be added.
  • D The family evpn signaling loops 2 parameter must be added.
Explanation

In an eBGP EVPN overlay, eBGP normally changes the BGP next-hop attribute when it re-advertises routes. On a spine, that behavior makes the spine address appear as the VXLAN tunnel endpoint. Configuring multihop no-nexthop-change preserves the originating leaf VTEP as the EVPN next hop, so remote leaves build VXLAN tunnels directly to the correct VTEP.
