This chapter details Generic UDP Encapsulation (GUE) configuration, covering tunnel setup, port assignment, and load balancing on Cisco routers.
Generic UDP encapsulation
This topic describes Generic UDP Encapsulation (GUE) on the Cisco 8000 Series Router, which encapsulates IPv4 and IPv6 packets in UDP to provide load-balancing entropy and efficient transport across networks.
Flexible assignment of UDP port numbers for decapsulation
This topic describes flexible assignment of UDP port numbers for Generic UDP Encapsulation (GUE) decapsulation on the Cisco 8000 Series Router, which lets you assign UDP port numbers from 1000 through 64000 to decapsulate IPv4, IPv6, and MPLS packets.
GUEv1 static tunnel configuration over IPv4 networks
This topic describes Generic UDP Encapsulation variant 1 (GUEv1) static tunnel configuration over IPv4 networks on the Cisco 8000 Series Router, which enables scalable and secure deployment of GUEv1 tunnels to carry IPv4 and IPv6 traffic.
Unidirectional GUEv6 for IPv6 traffic
This topic describes static Generic UDP Encapsulation (GUE) tunnels over an IPv6 underlay (GUEv6) on the Cisco 8000 Series Router, which enables scalable IPv4 and IPv6 overlay transport without dynamic tunnel discovery.
