Description

TENT: New Distance from RootNode(SourceId:

sourceId) to The Node(SourceId: sourceId) is distanceValue.

ISIS—procId—AREA

The distance to the root node is updated.

sourceId: source system ID.

The distances from the nodes to the root node are the same.

sourceId: source system ID.

Changed links.

sourceId: source system ID.

destId: destination system ID

oldCost: old path cost value

newCost: new path cost value

attAdjNum: Number of ATT neighbors

The adjacency protocol type or nexthop of the local node is changed.

distanceValue: Cost to the root node.

nexthopNum: Number of nexthops of the node

nbrNum: Number of neighbors of the node.

parentNum: Number of parent nodes.

For the link of the local node, the two-way check was ignored.

distanceValue: Cost to the root node.

nexthopNum: Number of nexthops of the node

nbrNum: Number of neighbors of the node.

parentNum: Number of parent nodes.

Area address-related information

A new area address is added.

newareaAddress: New area address

sysLevel: system level

topoType: topology type

l1referCount: Level 1 reference count of the area address.

l2referCount: Level 2 reference count of the area address.

Remove an area address.

oldareaAddress: Old area address

topoType: topology type

l1referCount: Level 1 reference count of the area address.

l2referCount: Level 2 reference count of the area address.

Information about PRC route updates

procId: IS-IS process ID.
