However, if you want to view all the routes BGP4 knowsabout, you can display the BGP4 table.To view the BGP4 route table, enter the following command.TABLE 123 BGP4 summary route informationThis field... Displays...Total number of BGP routes (NLRIs)InstalledThe number of BGP4 routes the BigIron RX has installed in the BGP4route table.Distinct BGP destination networks The number of destination networks the installed routes represent.
