Redistributing routes into IPv4 IS-IS

Routes can be redistributed for IPv4-IS-IS, and the routes to be redistributed can be specified.

About this task

The redistribution of static routes into IPv4 IS-IS is configured on device1. The redistribution of connected routes into IPv4 IS-IS is configured on device2, and the connected routes to be redistributed are specified.

1. On device1, enter the configure terminal command to access global configuration mode.
   

   device1# configure terminal

2. Enter the router isis command to enter IS-IS router configuration mode and enable IS-IS on the device.
   

   device1(config)# router isis
   

3. Enter the address-family ipv4 unicast command to enable ISIS address-family IPv4 unicast configuration mode.
   

   device1(config-isis-router)# address-family ipv4 unicast
   

4. Enter the redistribute command with the static parameter to redistribute static routes.
   

   device1(config-router-isis-ipv4u)# redistribute static
   

5. On device2, enter the configure terminal command to access global configuration mode.
   

   device2# configure terminal

6. Enter the router isis command to enter IS-IS router configuration mode and enable IS-IS on the device.
   

   device2(config)# router isis
   

7. Enter the address-family ipv4 unicast command to enable ISIS address-family IPv4 unicast configuration mode.
   

   device2(config-isis-router)# address-family ipv4 unicast
   

8. Enter the redistribute command with the connected and route-map parameters to redistribute connected routes and specify a route map.
   

   device2(config-router-isis-ipv4u)# redistribute connected route-map rmap1
   

Example

The following example redistributes static routes into IPv4 IS-IS on a device.

device# configure terminal
device(config)# router isis
device(config-isis-router)# address-family ipv4 unicast
device(config-router-isis-ipv4u)# redistribute static

Example

The following example redistributes connected routes into IPv4 IS-IS on a device and specifies a route map.

device# configure terminal
device(config)# router isis
device(config-isis-router)# address-family ipv4 unicast
device(config-router-isis-ipv4u)# redistribute connected route-map rmap1
