R211x-HP Flexfabric 11900 Layer 3 - IP Routing Command Reference

484
mdc-admin
Parameters
protocol: Redistributes routes from the specified routing protocol, which can be bgp4+, direct, isisv6,
ospfv3, ripng, or static.
process-id: Specifies the process ID of a routing protocol, in the range of 1 to 65536. It defaults to 1. This
argument takes effect only when the protocol is isisv6, ospfv3, or ripng.
all-processes: Redistributes routes from all the processes of the specified routing protocol. This keyword
takes effect only when the protocol is ripng, ospfv3, or isisv6.
allow-ibgp: Allows redistribution of IBGP routes. It is available only when the protocol is bgp4+.
cost cost: Specifies a cost for redistributed routes, in the range of 1 to 16777214. The default is 1.
route-policy route-policy-name: Uses the specified routing policy to filter redistributed routes. The
route-policy-name argument is a case-sensitive string of 1 to 63 characters.
type type: Specifies the type for redistributed routes, 1 or 2. It defaults to 2.
Usage guidelines
An external route is a route to a destination outside the OSPFv3 AS. External routes types are as follows:
• A Type-1 external route has high reliability. Its cost is comparable with the cost of OSPFv3 internal
routes. The cost from an OSPFv3 router to a Type-1 external route's destination equals the cost from
the router to the ASBR plus the cost from the ASBR to the external route's destination.
• A Type-2 external route has low credibility, so OSPFv3 considers the cost from the ASBR to a Type-2
external route is much bigger than the cost from the ASBR to an OSPFv3 internal router. The cost
from an internal router to a Type-2 external route's destination equals the cost from the ASBR to the
Type-2 external route's destination.
The import-route command cannot redistribute default routes.
The import-route bgp4+ command redistributes only EBGP routes. The import-route bgp4+ allow-ibgp
command redistributes both EBGP and IBGP routes, and might cause routing loops. Therefore, use it with
caution.
Examples
# Configure OSPFv3 process 1 to redistribute routes from RIPng and specify the type as type 2 and cost
as 50.
<Sysname> system-view
[Sysname] ospfv3
[Sysname-ospfv3-1] import-route ripng 10 type 2 cost 50
# Configure OSPFv3 process 100 to redistribute the routes discovered by OSPFv3 process 160.
<Sysname> system-view
[Sysname] ospfv3 100
[Sysname-ospfv3-100] import-route ospfv3 160
