Configuring ISIS properties on an interface
29
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.
• external1 – An OSPF type 1 external route.
• external2 – An OSPF type 2 external route.
• internal – An internal route calculated by OSPF.
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] |
metric <number> | metric-type [external | internal] |
route-map <name>
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 BigIron RX 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>]
The level-1 into level-2 | level-2 into level-1 parameter specifies the direction of the redistribution:
• level-1 into level-2 – Redistributes Level 1 routes into Level 2. This is the default.
• level-2 into level-1 – Redistributes Level 2 routes into Level 1.
The prefix-list <name> specifies an IP prefix list.
