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.

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.

Starting 4.32.2F CBF supports forwarding MPLS labeled traffic based on the EXP value in the incoming packet or the internal traffic class (TC) resolved from the parameters of the packet (e.g TC derived from EXP bits combined with port trust mode). Here, EXP bits refer to the Experimental bits in the MPLS header.

This mechanism allows for transceivers’ firmware to be updated without having to remove the transceiver from the switch. Firmware updates may be necessary in a testing or production environment to resolve potential firmware bugs. Some transceivers may also support firmware management operations in a hitless manner (without impacting traffic).
