show bgp {neighbor} remoteaddr {address-family [ipv4-unicast | ipv4-multicast |ipv6-unicast | ipv6-multicast | ipv4-vxlan | {l2vpn-evpn [inclusive-multicast | mac-ip | auto-discovery | esi | ip-prefix]}]} [accepted-routes | received-routes | rejected-routes | transmitted-routes] {detail} [all | as-path
path-expression | community [no-advertise | no-export | no-export-subconfed | number
community_number | autonomous-system-id : bgp-community] | network [any/netMaskLen | networkPrefixFilter] {exact}]
