EOS Border Gateway Protocol (BGP)

Border Gateway Protocol (BGP)
Border Gateway Protocol (BGP) is an exterior gateway protocol (EGP) that exchanges routing information among neighboring routers in different Autonomous Systems (AS). BGP version 4 is defined by RFC 4271.
Multiprotocol BGP (BGP4+) can carry routes from multiple address families (AFI) and sub-address families (SAFI) simultaneously over a single BGP peering. Multiprotocol BGP is defined by RFC 4760.
This chapter contains the following sections.
Arista switches support these BGP functions:
A single BGP instance
Simultaneous internal (IBGP) and external (EBGP) peering
Multiprotocol BGP
BGP Confederations
