Configuring IPv4 address family route parameters

Redistributing OSPF routes into IPv4 IS-IS

To redistribute OSPF routes into IPv4 IS-IS, enter the following command at the IPv4 IS-IS unicast
address family configuration level.
BigIron RX(config-isis-router-ipv4u)# redistribute ospf
This command configures the BigIron RX to redistribute all OSPF routes into Level-2 IPv4 IS-IS.
Syntax: [no] redistribute ospf [level-1 | level-1-2 | level-2] |
Most of the parameters are the same as the parameters for the redistribute static command.
However, the redistribute ospf command also has the match external1 | external2 | internal
parameter. This parameter specifies the OSPF route type you want to redistribute into IPv4 IS-IS. By
default, the redistribute ospf command redistributes only internal routes.

Redistributing BGP4+ routes into IPv4 IS-IS

To redistribute BGP4+ routes into IPv4 IS-IS, enter the following command at the IPv4 IS-IS unicast
address family configuration level.
BigIron RX(config-isis-router-ipv4u)# redistribute bgp
This command configures the router to redistribute all its BGP4 routes into Level-2 IPv4 IS-IS.
Syntax: [no] redistribute bgp [level-1 | level-1-2 | level-2] |
The parameters are the same as the parameters for the redistribute static command.

Redistributing IPv4 IS-IS routes within IPv4 IS-IS

In addition to redistributing routes from other route sources into IPv4 IS-IS, the device can
redistribute Level 1 IPv4 IS-IS routes into Level 2 IPv4 IS-IS routes, and Level 2 IPv4 IS-IS routes into
Level 1 IPv4 IS-IS routes. By default, the device redistributes routes from Level 1 into Level 2.
NOTE
The BigIron RX automatically redistributes Level 1 routes into Level 2 routes, even if you do not
enable redistribution.
For example, to redistribute all IPv4 IS-IS routes from Level 2 into Level 1, enter the following
command at the IPv4 IS-IS unicast address family configuration level.
BigIron RX(config-isis-router-ipv4u)# redistribute isis level-2 into level-1
The router automatically redistributes Level-1 routes into Level 2.
Syntax: [no] redistribute isis level-1 into level-2 | level-2 into level-1 [prefix-list <name>]
