Intermediate System to Intermediate System | 591Redistribute routesIn addition to filtering routes, you can add routes from other routing instances or protocols to the IS-ISprocess. With the redistribute command syntax, you can include BGP, OSPF, RIP, static, or directlyconnected routes in the IS-IS process.IPv4 routesUse any of the following commands in ROUTER ISIS mode to add routes from other routing instances orprotocols.Note: Do not route iBGP routes to IS-IS unless there are route-maps associated with the IS-ISredistribution.Note: These commands apply to IPv4 IS-IS only. Use the ADDRESS-FAMILY IPV6 mode shown later toapply prefix lists to IPv6 routes.Command Syntax Command Mode Purposeredistribute {bgp as-number | connected | rip |static} [level-1 level-1-2 | level-2] [metricmetric-value] [metric-type {external | internal}][route-map map-name]ROUTER ISIS Include BGP, directly connected, RIP, oruser-configured (static) routes in IS-IS.Configure the following parameters:• level-1, level-1-2, or level-2: Assignall redistributed routes to a level.Default is level-2.• metric range: 0 to 16777215.
