Tag :: IP-Over-UDP

This feature when configured enables users to rewrite the DSCP of the GUE encapsulated header on IP-over-UDP tunnels while preserving the TOS value of the inner IP ( IPv4 / IPv6 ) payload. Starting from software version 4.34.1F, the CLI configuration to enable or disable DSCP preserve globally on the egress interface introduces a clear distinction in the behavior of GUE encapsulation on the core facing interface of the IP-over-UDP tunnels.

Generic UDP Encapsulation (GUE) is a general method for encapsulating packets of arbitrary IP protocols within a UDP tunnel. While GUE supports an extensible header format with optional data, currently we only support the variant 1 header format, which directly encapsulates the IPv4/IPv6 payload without a GUE header.
