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.

At a high level, L1 profiles are a set of configurations which allow EOS users to change the numbering scheme and default L1 configurations of all front panel interfaces across their network switch. On Arista network switches, front panel transceiver cages are exposed as ports which are numbered sequentially: 1, 2, 3, 4, etc. These identifiers are usually marked on the front panel to allow for easier identification.

For packets received on the front-panel interfaces and delivered to the CPU interface, this feature allows creation of a profile to configure buffer reservations for the egress CPU queues in the MMU (MMU = Memory Management Unit which manages how the on-chip packet buffers are organized).

For packets sent and received on the front-panel interfaces, this feature allows creation of a profile to configure buffer reservations in the MMU (MMU = Memory Management Unit which manages how the on-chip packet buffers are organized). The profile can contain configurations for ingress and egress. On the ingress, configuration is supported at both a port level as well as a priority-group level.
