Configuring the number of VRFs for IPv4 and IPv6
Clears the imported IPv6 routes for the specified nexthop ID on the interface module (LP).
Configuring the number of VRFs for IPv4 and IPv6
To limit the number of imported IPv4 or IPv6 routes into any VRF including the default VRF, the
following command is available in the global configuration mode and not available in any individual
VRF mode. Changes in the value in the global configuration mode will be effective in all VRFs.
Brocade(config)# [ip|ipv6] max-import-vrfs 1-2048
The no command will set the value to the default value, which is 50.
If you configure ip max-import-vrfs to a number which is less than the currently imported routes in
the IPv4 or IPv6 address family for any VRF, then the following error will be displayed and the
configuration will not be accepted.
Brocade(config)# [ip|ipv6] max-import-vrfs 2
Error: VRF one has 3 import commands configured in ipv4/ipv6 address families
The configured non-default value of ip/ipv6 max-import-vrfs may be displayed using the show ip or
show ip vrf-name commands.
NOTE
A system maximum of 1000 import commands (including all VRFs, IPv4 and IPv6 address families)
can be defined.
Modified CLI commands
The Inter-vrf routing feature makes it possible to import OSPF routes from one VRF to another VRF.
There may be a need to advertise the imported OSPF routes back to the OSPF domain as external
routes. This requires redistribution of OSPF into OSPF again, which was not supported In prior
releases. With the introduction of redistribution, the following configuration is supported:
This command is applicable to OSPF, RIP and BGP. Currently IS-IS does not support VRFs and it is
not possible to have IS-IS running in multiple VRFs.
If you configure to import the same protocol routes into the same protocol, then RTM will send back
protocol routes belonging to other VRFs.
Redistribution of a protocol into itself is supported for the following protocols:
• IPv4
Brocade(config-ospf-router)#redistribute ospf route-map <route-map-name>
bgp Border Gateway Protocol (BGP)
connected Connected
isis Intermediate System to Intermediate System (IS-IS)
rip Routing Information Protocol (RIP)
static Static routes
ospf OSPF routes (new addition)
