BGP LU/SR (labeled-unicast with segment routing) support in multi-agent mode

This feature implements RFC3107 that allows carrying a label stack with BGP route updates, using multi-protocol BGP. It also implements segment routing extensions that allow accepting and carrying the transitive segment-index (SID) attribute in LU route updates. This implementation is for multi-agent mode. BGP LU for ribd mode is supported since 4.17.0F, see details in the following location: https://eos.arista.com/eos-4-17-0f/bgplu/ The following BGP LU features are supported starting from release 4.20.5F: Basic IPv4 BGP LU, both receiving LU updates and originating/re-advertising LU routes to other peers IBgp and EBgp peering for LU peers Using ISIS-SR (or other MPLS tunnels) as the...

Igmp Snooping Proxy

IGMP Snooping Proxy feature is an optimization over IGMP snooping. When IGMP Snooping Proxy is enabled, the switch gathers IGMP reports from downstream hosts by sending queries periodically and updates its local state. Later, when it receives a query from an upstream router, the switch responds with a report immediately based on its local state. When IGMP Snooping Proxy is not enabled, IGMP Snooping floods the query in the VLAN for the hosts to respond with a report and the reports are flooded to ports that are known to have multicast routers. Enabling IGMP Snooping Proxy prevents a sudden burst...
