Use bearer tokens to provide custom applications or third-party applications, like Ansible, login access to CloudVision. Doing so will allow the application to make configuration changes to EOS devices. Bearer token login can be used with identity providers that issue bearer tokens and have an introspection endpoint. Okta and PingIdentity have been tested for use with CloudVision.

This document describes BFD RFC7130 mode on EOS. RFC7130 defines a mechanism to run BFD protocol over port channels with an independent asynchronous BFD session on every port channel member link. With RFC7130 support, the port channel member link will be removed from forwarding if the BFD session state transitions from UP to DOWN on the member link. This is useful for quickly detecting failures where L1 stays connected but the interface is unable to forward traffic.

BGP inbound update processing delay is a feature in EOS where an optional delay is applied prior to processing inbound UPDATE messages from a peer(s). The duration of the delay is configurable per peer. The delay is applied to UPDATE messages for all the address families that are negotiated with the peer. The delay timer starts when the peer becomes established. The routes from such peers are processed only after the timer expires. Any routes received after the timer expired are processed as usual without the delay. Both the default VRF and non-default VRFs are supported.

BGP Monitoring Protocol (BMP) allows a monitoring station to connect to a router and collect all of the BGP announcements received from the router’s BGP peers. The announcements are sent to the station in the form of BMP Route Monitoring messages generated from path information in the router’s BGP internal tables. A BMP speaker may choose to send either Adj-Rib-In routes, or Loc-Rib routes (as defined by RFC9069), or both.

When a core router has competing advertisements for the same prefix from various PEs, the local edge route should be selected as the best path based on the IGP metric of the resolving routes of those competing advertisements. Without the support mentioned in this TOI, when a BGP route has two or more levels of recursion, the BGP process does not utilize the IGP distance in the route selection process.

This allows EOS to direct specific services over the specified RIB domains, overriding the default behavior.

BGP Prefix Independent Convergence (PIC Edge) refers to fast re-convergence of traffic destined for BGP prefixes on a network event affecting the best path(s) such that the time taken to switch traffic from the active best path(s) to the next best path (i.e. backup path) is independent of the number of prefixes. The above behavior is achieved by pre-programming the best path and alternate backup path in the forwarding agent in steady state.

Bidirectional Protocol Independent Multicast (PIM) allows routers to build trees to deliver multicast traffic from sources to receivers. It is a variant of sparse-mode PIM that efficiently addresses the use case where receivers for a multicast group are also sources for that group. While sparse-mode PIM builds shared trees and source-specific trees, bidirectional PIM only builds shared trees. A shared tree for a multicast group is rooted at the Rendezvous Point (RP) for that group. The RP for a bidirectional group is an IP address, which may or may not be real, but is reachable via all routers in the multicast domain. There may be multiple RPs in a multicast domain.
