due to my lack of route reflectors in my backbone, I need the use of bgp additional paths like
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bgp/configuration/xe-3s/irg-xe-3s-book/irg-additional-paths.html
or on
Nokia / alcatel
Platforms Supported : 7210 SAS-R6, 7210 SAS-M (network mode), 7210 SAS- X BGP Add-Path capability allows a BGP router to send to its BGP peers more than one path for the same prefix/NLRI. The base BGP standard does not provide for such a capability; if a BGP router learns multiple paths for the same NLRI, it selects only one as its best path, and this is the only path that is allowed to be advertised to B GP peers. Advertising multiple paths has several benefits including reduced routing churn an d faster convergence . The ability to send and/or receive multiple paths per prefix/NLRI must be negotiated with a BGP peer during capability negotiation. This release supports Add-P ath for MP-iBGP sessions established by the VPN-IPV4 and VPN-IPV6 routes. It is not supported f or eBGP sessions (for both IPV4 and IPv6) and for VPRN PE-CE BGP sessions, LBL-IPv4, IP v6, VPN-IPv6 and 6PE routes. The maximum number of paths to send is configurable per peer and per address family. The actual set of advertised paths depends on the number available in the RIB-IN, the next-hop diversity of the paths, BGP route advertisement rules, export policies and other BGP configuration options.
Does anybody know, how this feature is called on huawei NE20 Routers or S6720 Switches?
Thanks for your Help
Best regards
Florian
