With the redistributecommand syntax, you can include BGP, OSPF, RIP, static, or directly connected routes in the IS-IS process.NOTE: Do not route iBGP routes to IS-IS unless there are route-maps associated with the IS-IS redistribution.To add routes from other routing instances or protocols, use the following commands.NOTE: These commands apply to IPv4 IS-IS only. To apply prefix lists to IPv6 routes, use ADDRESS-FAMILY IPV6 mode, shownlater.• Include BGP, directly connected, RIP, or user-configured (static) routes in IS-IS.ROUTER ISIS moderedistribute {bgp as-number | connected | rip | static} [level-1 level-1-2 | level-2] [metricmetric-value] [metric-type {external | internal}] [route-map map-name]Configure the following parameters:• level-1, level-1-2, or level-2: assign all redistributed routes to a level. The default is level-2.• metric-value the range is from 0 to 16777215. The default is 0.• metric-type: choose either external or internal. The default is internal.• map-name: enter the name of a configured route map.• Include specific OSPF routes in IS-IS.494 Intermediate System to Intermediate System
