Chapter 8 Managing PNNI Nodes and PNNI Routing
Managing PNNI Nodes
lists the parameter descriptions for the addpnni-summary-addr command.
Configuring SVCC RCC Variables
Configure SVCC-based RCC variables with the cnfpnni-svcc-rcc-timer command as follows:
mgx8830a.1.PXM.a >
cnfpnni-svcc-rcc-timer <
node-index
> [-initTime] [-retryTime]
[-callingIntegrityTime] [-calledIntegrityTime]
This defines a node’s initial PNNI SVCC-based variables, as shown in
.
Configuring Routing Policies for Shortest Path Tables
The shortest path tables (SPTs), which are also called background routing tables, are created by default
to store the shortest paths or routes to all destinations. These SPTs can be divided into three groups as
described in the Cisco PNNI Network Planning Guide for MGX and SES Products. Each group stores
routes that are optimized for one of the following routing metrics: AW, CTD, or CDV. Within each group,
tables are created for each CoS that uses the routing metric.
Table 8-1
Parameters for addpnni-summary-addr Command
Parameter
Description
node-index
The node index assigned to a PNNI logical node on a network.
Range = 1 – 65535
address-prefix
The ATM address prefix assigned to the network.
prefix-length
The length of the summary address-prefix in number of bits, equal or less than
152 bits. Currently, the zero-length summary address is not supported.
-type
The type of the summary address.
-suppress
true = summary address is not advertised.
-state
The summary address is advertised | notadvertised | inactive.
Table 8-2
Parameters for cnfpnni-svcc-rcc-timer Command
Parameter
Description
node-index
Node index.
-initTime
Time (in seconds) that the node delays establishment of an SVCC to a
neighbor with a numerically lower ATM address, after determining that such
an SVCC should be established.
-retryTime
Time (in seconds) that the node delays before attempting to re-establish an
SVCC-based RCC after the RCC is unexpectedly torn down.
-callingIntegrityTime
Time (in seconds) that the node waits for a sent SVCC to become fully
established before giving up and tearing it down.
-calledIntegrityTime
Time (in seconds) that the node waits for a received SVCC to become fully
established before giving up and tearing it down.
