X Arista Networks, Inc.This is done for BGP by disseminating BGP link bandwidth extended community attribute information with BGP paths such that the receiver device of all such paths for a route programs next hops Description Routing control functions RCF is a new language that can be used to express BGP route filtering and attribute modification logic in a powerful and programmatic fashion.
It supports a new set of workflows to define and apply these functions in EOS. Additionally to the existing information, the command will now also display the time since a route was last updated in the routing table when in multi-agent mode.
This additional information would allow a network operator to check if and when a route was updated in the routing table to correlate possible network issues caused by routing updates e.
This feature adds support for the following: Redistribution of leaked static, connected, Ospf, and IS-IS routes into Ospf Redistribution of leaked static, connected, and Ospf routes into IS-IS Platform compatibility Redistribution of leaked routes is supported on all EOS devices, but only with the routing system in multi-agent mode.Hevüy
Description This feature introduces a metric for static routes so that the user can configure both administrative distance and metric for a static route. Administrative distance precedes metric when comparing configured routes. Lower metric route will win among routes with the same administrative distance. One use case of static route metric is to impact BGP best path selection. Route Arbitration case 1 — route with lower admin distance wins ip route An example of one such deployment involves learning routes from a route reflector which itself is getting both 6PE and IPv6 unicast routes.
The goal of this feature is to add support for configuring both 6PE and IPv6 unicast on a single peer, which were previously mutually exclusive. Platform compatibility This feature would work on all platforms supporting 6PE.
Configuration A new command is now available to configure both 6PE and ipv6-unicast With the 4. Platform Compatibility Supported on all platforms. Description When there are multiple VRFs on the device and there is a need to share routes between them, typically for shared services, such routes are called leaked routes. For more info on inter VRF route leaking, please refer to the article in Resources section.
Introduction For many years, network deployments for enterprise Internet edge environments have consisted of dedicated routing platforms and a switching or aggregation layer to distribute this to various network zones. Description This feature adds support for a dynamic configuration model to eliminate the need for the network administrator to assign and configure IPv6 addresses for BGP peering.
We leverage the following details to automatically establish BGP adjacency: IPv6 link local addresses can be, and typically are, automatically generated by the system based on MAC addresses. IPv6 router advertisements can be used to communicate these addresses among potential BGP peers.
This feature may be used when a policy to filter routes on the basis of the resolved interface of a route is desired. Extended gateway data was already supported in gated mode. Now it is being supported for multi-agent mode arBGP. Starting in EOS 4. Description Starting with EOS release 4. Description 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. Through peering relationships with MSDP-speaking routers in other PIM-SM domains, an MSDP speaker can learn of multicast sources in these domains, and interested receivers in its own can then be delivered multicast data from these over an inter-domain distribution tree.
Existing support is in place for MSDP with the ribd routing protocol model.When a Tc-To-Cos profile is applied to an interface then all the packet egressing through this interface will follow the below principles: Cos remarking will happen based on the TC, Dp Drop precedence of the packet.
The exact value of the cos will depend on the mapping present in the tc-to-cos profile applied to it Incoming DHCP client Description This feature provides multipath router-id, a new multipath mode to control the behavior of RPF selection.
Arista 7050X3 Series Network Switch - Quick Look
In the default multipath mode, it is possible that downstream Pim neighbors will select as RPF different upstream Pim neighbors despite having the same ECMP routes to the source. This may have the undesirable effect that the source has to deliver to multiple upstream Pim neighbors instead of one.
When multipath router-id is configured, traffic for a group or source-group will be routed through only one upstream PIM neighbor for all downstream PIM neighbors given that these neighbors have the same ECMP routes Description Starting with EOS release 4. This new tag qualifier provides more control to the users so that they can choose from different action behaviors depending on their security objectives and the hardware resource constraint of a deployment.
For firewall policies tagged with the redirect tag, MSS extracts IP addresses from the policy and forwards all traffic destined to or generated from that set of IP addresses to the firewall.
With the additional verbatim tag, the user now can After accounting for the CPU and drop port numbers the labels are available for use and 0 is reserved to indicate not configured. This is done by setting the number of bits that can be used by the qualifier field LDAP can be used for authentication and authorization.
Platform Compatibility This feature is platform independent. Configuration This feature has several configuration options, the only one of which is required is authentication. A complete sample config is shown below and each subsection describes the use of the settings.
This essentially means that the BGP paths with same AS-path lengths shall be considered equal cost irrespective of whatever the AS-path content is.
This CLI knob, when disabled, inserts a new bestpath step at number 8 into the bestpath selection algorithm which does the as-path content comparison to choose a Description In a typical switch deployment, multiple ports can have the same configuration, such as description and access VLAN.Dynavap phantom
Any changes made in the profile will automatically update the configurations of the interfaces using the profile. Platform Compatibility All platforms support this feature. Configuration The following shows how to configure an interface profile and an Prior to this release, filtered prefixes were configured one at a time. With EOS 4. This feature is available with both the multi-agent routing protocol model and the ribd routing protocol model.
Platform compatibility This feature is available on all platforms.
Configuration The area filter command It can be enabled on level-1 or level-2 or both. Once enabled, any purge LSP that is originated by the node will be added with a purge originator TLV which will contain its own system-id.The X Series provide flexible options for scalable two-tier network designs and incorporate traffic control, monitoring and provisioning features that support ease of use.

X Arista Networks, Inc.I have multiple access ports with multiple VLANs. There is one port-channel consisting of two ethernet interfaces going to a Juniper router for inter-vlan routing. I just wanted to confirm what configurations do I need on port-channel going to my router apart from configuring it as trunk switchport mode trunk and specifying allowed vlans.
My current setup is not working. Can we confirm if the port-channel has active ports on it? Also you can check the output of show vlan to confirm if Port-channel is a part of those vlans. Do we see the MAC address of the Juniper device getting learnt on the port-channel of Arista under show mac-address table? It might be possible that the Arista switch is forwarding the traffic out of the port-channel and getting dropped on the other side.
See the below example:. Consider the port-channel is Po9 and the source-IP is 1. Create the ACL as below:. If it doesn't increment, then it means it is getting dropped on Arista for some reason which we need to check. In that case, make sure to configure a static ARP on the source host.
Arista 7050X3 Series
Let us know if you need help with that. Also ensure Source host is actually sending traffic. Apparently, the problem was somewhere else but it was good to know that I did not miss any simple configuration on Arista that caused inter-vlan routing to fail.Elevated hunting cabins
Also, since Arista does not capture packets that are simply switched, the idea of creating ACLs by Aniket was something I desperately needed! But now since the release of EOS It is a great tool for troubleshooting and inspection of packets in the network.
