Tag :: Multi Agent

This feature implements RFC3107 that allows carrying a label stack with BGP route updates, using multi protocol BGP.

In the multi agent routing protocol model, the Bgp agent now supports matching community lists with a logical OR via

The replace remote AS feature allows a provider edge (PE) router to change the autonomous system (AS) number used by a

Sflow samples can be augmented with additional Extended gateway data by getting data from BGP in addition to

This feature implements support for RFC8203/BIS so that users can attach the reason of BGP instance or peer session

This feature adds support for BGP UCMP in the multi agent routing protocol model. The TOI for BGP UCMP in the ribd

This feature extends the BGP Layer 3 VPN Import/Export and VRF Route Leaking functionality to “default” VRF.

The “maximum-paths <m>” (default m=1) configuration that controls BGP’s multipath behavior, is available as a global knob, and not as a peer/peer-group knob today in EOS. When “maximum-paths” CLI is configured with m > 1, BGP starts forming ECMP groups for paths with similar attributes received from all configured neighbors.

Routing control functions (RCF) is a new language, a different way of policy definition and application in a programmatic fashion (https://www.arista.com/en/support/toi/eos-4-27-2f/15102-routing-control-functions-language-and-configuration). EOS Application Programmable Interface (eAPI) is another means whereby commands are sent to the switch (i.e. aside from the switch’s command-line interface - CLI which has been the norm), which can be executed through various methods like web interface, shell or a program/script.

The Multicast Source Discovery Protocol (MSDP) provides a mechanism to connect together multiple PIM Sparse Mode

EOS supported two routing protocol implementations: multi-agent and ribd. The ribd routing protocol model is removed starting from the EOS-4.32.0F release. Multi-agent will be the only routing protocol model. Both models largely work the same way though there are subtle differences.

Add support for dynamic prefix list based matching in multi agent model. Please refer the TOI for rib

This feature adds support for specifying Resolution Rib Profile as system-connected per-via (next-hop) for static routes. System-connected means that a static route is only resolved if the next-hop is reachable over a connected route. If system-connected is not specified, it means that the static route is resolved if the next-hop is reachable over any kind of route in the routing FIB, including a connected route as well as a tunnel rib.

When there are multiple VRFs on the device and there is a need to share routes between them, typically for shared

VRF Route leaking can be used when routes from one VRF are required in another VRF (e.g. in case of shared services). If VrfLeak Agent is being used to leak routes, the leaked routes (in destination VRF) can be redistributed into IGPs.

This feature adds support for ‘match interface’ clause under route map config for Bgp policy application in

Traffic steering enables traffic for a specified set of prefixes to get forwarded along traffic engineered paths

Support for negotiating and receiving IPv6 unicast and IPv6 labeled unicast (6PE) updates from a BGP peer.

This feature gives users the ability to use Route Control Functions (RCFs) to create custom policies for deciding which routes with IP next-hops should be programmed into the kernel with fwd* next-hop devices so the associated kernel packets are inserted into the ingress pipeline of hardware forwarding instead of being software-forwarded by the kernel.

This feature adds support for static inter-VRF routes. This enables configuration of routes to destinations in one ingress VRF with an ability to specify a next-hop in a different egress VRF through a static configuration.

This feature introduces a new CLI command (agent Bgp snapshot mrt received routes [ VRF ] FILE) which generates an MRT file containing the peers, prefixes and path attributes received by a switch running multi-agent routing m

Currently EOS supports redistribution into BGP at the global (instance) level. Also EOS supports redistribution in

This feature adds support for redistributing EOS SDK routes into IS-IS in the multi-agent routing protocol model. This feature existed in the single agent model by the configuration of redistribute static since EosSdk routes are treated as static routes in the single agent model. 

The CLI command “show rib route ip[ipv6]” and its sub commands (e.g. “show rib route ip

In the ribd routing protocol model, the “maximum paths … ecmp …” command allows restricting the number of BGP

Default routing protocols model will be set to multi-agent in 4.30.1. Note that the default value is only used if a value is not specified in startup-config.
