Displaying OSPF V3 Information
For example, to display the SPF tree for area 0, enter the show ipv6 ospf spf tree area command at
any level of the CLI.
Syntax: show ipv6 ospf spf tree area <area-id>
The tree keyword displays the SPF table.
The area <area-id> parameter specifies a particular area. You can specify the <area-id> in the
following formats:
• As an IPv4 address; for example, 192.168.1.1.
• As a numerical value from 0 – 2,147,483,647.
In this sample output, consider the SPF node with the router ID 223.223.223.223 to be the top
(root) of the tree and the local router. Consider all other layers of the tree (223.223.223.223:88
and 1.1.1.1:0) to be destinations in the network. Therefore, traffic destined from router
223.223.223.223 to router 1.1.1.1:0 must first traverse router 223.223.223.223:88.
TABLE 231 OSPF V3 SPF table
Field Description
Destination The destination of a route, which is identified by the following:
• “R”, which indicates the destination is a router. “N”, which indicates the destination is a
network.
• An SPF node router ID (IPv4 address). If the node is a child node, it is additionally
identified by an interface on which the node can be reached appended to the router ID in
the format <router-id>:<interface-id>.
Bits A bit that indicates the capability of the Brocade device. The bit can be set to one of the
following:
• B – The device is an area border router.
• E – The device is an AS boundary router.
• V – The device is a virtual link endpoint.
• W – The device is a wildcard multicast receiver.
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 router should be included in IPv6 routing calculations.
E – The router floods AS-external-LSAs as described in RFC 2740.
MC – The router forwards multicast packets as described in RFC 1586.
N – The router handles type 7 LSAs as described in RFC 1584.
R – The originator is an active router.
DC –The router handles demand circuits.
Cost The cost of traversing the SPF node to reach the destination.
Next hop The IPv6 address of the next hop-router.
Interface The router interface through which to access the next-hop router.
