Displaying OSPFv3 SPF information
You can display the following OSPFv3 SPF information:
•
SPF node information for a specified area.
•
SPF table for a specified area.
•
SPF tree for a specified area.
For example, to display information about SPF nodes in area 0, enter the following command at any
level of the CLI:
Syntax: show ipv6 ospf spf node area [area-id]
The node keyword displays SPF node information.
The area area-id parameter specifies a particular area. You can specify the area-id in the following
formats:
Options
A 24-bit field that enables IPv6 OSPF routers to support the optional
capabilities. When set, the following bits indicate the following:
V6 – The device should be included in IPv6 routing calculations.
E – The device floods AS-external-LSAs as described in RFC 2740.
MC – The device forwards multicast packets as described in RFC 1586.
N – The device handles type 7 LSAs as described in RFC 1584.
R – The originator is an active router.
DC –The device handles demand circuits.
Area
The area whose link state information has led to the routing table entry's
collection of paths.
Cost
The type 1 cost of this route.
Type2 Cost
The type 2 cost of this route.
Next-Hop Router
The IPv6 address of the next router a packet must traverse to reach a
destination.
Outgoing Interface
The router interface through which a packet must traverse to reach the
next-hop router.
