Redistribute routes
In addition to filtering routes, you can add routes from other routing instances or protocols to the IS-IS
process. With the
redistribute command syntax, you can include BGP, OSPF, RIP, static, or directly
connected routes in the IS-IS process.
IPv4 routes
Use any of the following commands in ROUTER ISIS mode to add routes from other routing instances or
protocols.
distribute-list prefix-list-name out [bgp
as-number | connected | ospf process-id | rip |
static]
ROUTER ISIS-AF
IPV6
Apply a configured prefix list to all outgoing
IPv6 IS-IS routes. You can configure one of
the optional parameters:
• connected: for directly connected routes.
• ospf process-id: for OSPF routes only.
• rip: for RIP routes only.
• static: for user-configured routes.
• bgp: for BGP routes only

IPV6
Deny RTM download for pre-existing
redistributed IPv6 routes
Note: Do not route iBGP routes to IS-IS unless there are route-maps associated with the IS-IS
redistribution.
Note: These commands apply to IPv4 IS-IS only. Use the ADDRESS-FAMILY IPV6 mode shown later to
apply prefix lists to IPv6 routes.
