  • Multiple VXLAN tunnel reachability
    Patent number: 10382319
    Abstract: Embodiments are directed to facilitate multiple tunnels to be reachable via inter-chassis ling from virtual link trunking (VLT) peers and also to avoid traffic tromboning with an optimal path to all next hops. During initialization, a default egress object is created through an ICL with the next hop defined as VLT peer2 by setting the MAC address to be the MAC address of the VLT peer2, and the VLAN to be any one of the L3 spanned VLANs. When any of the VXLAN tunnels are resolved through ICL LAG, the process uses the default egress object created on ICL. Using the default egress object created on ICL, any traffic from VLT peer1 intended to go through ICL is terminated on VLT peer2 and will get routed again to their respective next hops. This creates a single egress object to the VLT peer and allowing multiple VXLAN tunnels to be reachable through ICL with optimal path towards all next hops.
