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 “This email address is being protected from spambots. You need JavaScript enabled to view it.” or “This email address is being protected from spambots. You need JavaScript enabled to view it.” 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.
