OSPF Name Aggregation
Monitoring Network OSPF Name Activity
ATM Services Configuration Guide for CBX 3500, CBX 500, GX 550, and B-STDX 9000 1/19/05G-9
The output from the show ospf names command will be slightly different on each
switch in the network. The following text shows the output for each switch in the
sample network shown in Figure G-2, including the results of OSPF name aggregation
used in provisioning addresses for the network.
The sample output shows that the port prefixes are aggregated by the node prefixes so
that only the node prefix is shared with other network switches. (The OSPF names
associated with the port prefixes only consume memory at the local switch.) The one
exception in the sample output is the port prefix 202666 on Switch#1. This prefix does
not follow the hierarchical numbering plan used in the network and, as a result, the
OSPF name associated with it must be advertised to all switches in the network.
