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 adds the support for OSPFv3 multi-site domains (currently this feature is added for IPv6 address family only) described in RFC6565 (OSPFv3 as a Provider to Customer Edge Protocol for BGP/MPLS IP Virtual Private Networks (VPNs) ) and enables routes BGP VPN routes to retain their original route type if they are in the same OSPFv3 domain. Two sites are considered to be in the same OSPFv3 domain if it is intended that routes from one site to the other be considered intra-network routes.

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.
