● Include BGP, directly connected, RIP, or user-configured (static) routes in IS-IS.
ROUTER ISIS mode
redistribute {bgp as-number | connected | rip | static} [level-1 level-1-2 | level-2]
[metric metric-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.

redistribute ospf process-id [level-1| level-1-2 | level-2] [metric value] [match
external {1 | 2} | match internal] [metric-type {external | internal}] [route-map map-
name]
Configure the following parameters:
○ process-id the range is from 1 to 65535.
○ 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.
○ match external the range is from 1 or 2.
○ match internal
○ metric-type: external or internal.
○ map-name: enter the name of a configured route map.
Redistributing IPv6 Routes
To add routes from other routing instances or protocols, use the following commands.
NOTE:
These commands apply to IPv6 IS-IS only. To apply prefix lists to IPv4 routes, use the ROUTER ISIS mode
previously shown.

To view the IS-IS configuration globally (including both IPv4 and IPv6 settings), use the show running-config isis
command in EXEC Privilege mode. To view the current IPv4 IS-IS configuration, use the show config command in ROUTER
