Configuring Ospfv3 Routing Information Management - 3Com Switch 4800G 24-Port Configuration Manual

Prerequisites
Configuring an OSPFv3
Stub Area
Configuring OSPFv3
Virtual Links
Configuring OSPFv3
Routing Information
Management
Enable IPv6 packet forwarding
■
Configure OSPFv3 basic functions
■
Follow these steps to configure an OSPFv3 stub area:
To do...
Enter system view
Enter OSPFv3 view
Enter OSPFv3 area view
Configure the area as a stub
area
Configure the default route
cost of sending a packet to
the stub area
n
Configurations on the OSPFv3 routers attached to the same area must be
■
consistent. Otherwise, neighbor relationships cannot be established between
adjacent routers.
You cannot delete an OSPFv3 area directly. Only when you remove all
■
configurations in area view and all interfaces attached to the area become
down, can the area be removed automatically.
All routers attached to a stub area must be configured with the stub
■
command. The keyword no-summary is only available on the ABR.
If you use the stub command with the keyword no-summary on an ABR, the
■
ABR distributes a default summary LSA into the area rather than generating an
AS-external-LSA or Inter-Area-Prefix-LSA. The stub area of this kind is also
known as totally stub area.
You can configure virtual links to maintain connectivity between non-backbone
areas and the backbone, or in the backbone itself.
Follow these steps to configure a virtual link:
To do...
Enter system view
Enter OSPFv3 view
Enter OSPFv3 area view
Create and configure a
virtual link
n
Both ends of a virtual link are ABRs that are configured with the vlink-peer
command.
This section is to configure management of OSPF routing information
advertisement and reception, and route redistribution from other protocols.
