Abstract: Techniques are described for providing fast reroute for traffic in EVPN-VXLAN. For example, a backup PE device of an Ethernet segment is configured with an additional tunnel endpoint address (“reroute tunnel endpoint address”) for a backup path associated with a second split-horizon group that is different than a tunnel endpoint address and first split-horizon group for another path used for normal traffic forwarding. The backup PE device sends the reroute tunnel endpoint address to a primary PE device of the Ethernet segment, which uses the reroute tunnel endpoint address to configure a backup path to the backup PE device over the core network. For example, the primary PE device may install the reroute tunnel endpoint address within its forwarding plane and one or more operations to cause the primary PE device to encapsulate a VXLAN header including the reroute tunnel endpoint address when rerouting the packet along the backup path.

Abstract: The application provides an enzyme immobilization carrier and a preparation method thereof, an immobilized enzyme and a preparation method thereof.
