TABLE 82 show ipv6 ospf spf table area output descriptions
This eld Displays
Destination The destination of a route, which is identied by the following:
• "R", which indicates the destination is a router. "N", which
indicates the destination is a network.
• An SPF node’s device ID (IPv4 address). If the node is a child
node, it is additionally identied 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 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 eld 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 oods 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.
For example, to display the SPF tree for area 0, enter the following command at any level of the CLI.
device# show ipv6 ospf spf tree area 0
SPF tree for Area 0
+- 10.223.223.223 cost 0
+- 10.223.223.223:88 cost 1
+- 10.1.1.1:0 cost 1
Syntax: show ipv6 opsf spf tree area area-id
The tree keyword displays the SPF table.
The area area-id parameter
species 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 through 2,147,483,647.
In this sample output, consider the SPF node with the router ID 10.223.223.223 to be the top (root) of the tree and the local router.
Consider all other layers of the tree (10.223.223.223:88 and 10.1.1.1:0) to be destinations in the network. Therefore, trac destined
from router 10.223.223.223 to router 10.1.1.1:0 must rst traverse router 10.223.223.223:88.
