Configuring IPv4 address family route parameters
Syntax: [no] redistribute ospf [level-1 | level-1-2 | level-2 ] |
match [external1 | external2 | internal] |
metric number |
metric-type [external | internal] |
route-map name
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.
Brocade(config-isis-router-ipv4u)# redistribute bgp
This command configures the device 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 Brocade 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 Brocade device 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.
Brocade(config-isis-router-ipv4u)# redistribute isis level-2 into level-1
The device 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.
