BGP triggered IP-in-GUE Encapsulation provides a mechanism for dynamically creating tunnels in a core network using an IP underlay.  IP-in-GUE (Generic UDP Encapsulation) encapsulates IP traffic in an IPv4/UDP header.  IP unicast routes to destinations reachable across the core network are learned via BGP at the ingress edge.

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.

MPLS over GUE (Generic UDP Encapsulation) is a tunneling mechanism for encapsulating MPLS IP traffic in a UDP header. This feature adds support for MPLS over GUE encapsulation for BGP VPN routes resolving over IPv4 next hops. 

This feature allows a compatible SSH client to authenticate to EOS via a FIDO2-anchored SSH key via the “このメールアドレスはスパムボットから保護されています。閲覧するにはJavaScriptを有効にする必要があります。” or “このメールアドレスはスパムボットから保護されています。閲覧するにはJavaScriptを有効にする必要があります。” key types. In OpenSSH this was introduced in version 8.2p1. This feature is not compatible with the Federal Information Processing Standards (FIPS)restrictions mode in EOS; if both are configured, this feature will take precedence.
