Configuring IP Routing
Maximum
Number of Routes Enter the maximum number of routes that you want added
to the routing table. The default number of routes is 16384.
Note: These routes refer only to IP Unicast entries.
Maximum
Number of ARP
Cache Entries Enter the maximum number of ARP cache entries. ARP
entries refers to the space available for the ARP cache.
When you increase the number of entries, it may cause the
table to be relearned more frequently. Consequently, it will
make address space usage more efficient. The default
maximum number of entries is 16384.
Route Preference
by Protocol This section describes the routing preferences set up
according to the network administrator’s preferences.
These preferences are normally set up using the most to
least trust. For example, local routes are normally
considered to have more trust or a higher preference, while
OSPF external routes are considered to have less trust or a
lower preference. These preferences can be overridden,
but careful consideration must be given when setting each.
Note: Local Routes must always have the higher
preference.
Note: Do not change the Preferences unless you are
certain of the consequences. Incorrect Preference
settings can cause the switch to stop all routing.
Local Routes Enter a preference value for local routes.
Note: Local Routes must always have the higher
preference.
High-Preference
Static Routes Enter a preference value for High preference static routes.
OSPF Intra-area
Routes Enter an OSPF intra-area route. A lower number indicates
a lower preference for the path.
OSPF Inter-area
Routes Enter the inter-area paths to destinations in other OSPF
areas. These are discovered through the examination of
received summary Link State Advertisements (LSA).
Enter a number to specify your path cost. A lower number
indicates a lower preference for the path.
OSPF External
Routes Enter the number of external paths to destinations external
to the Autonomous System (AS). These are detected
through the examination of received AS external LSAs.
Enter a number to specify your path cost (preference). A
lower number indicates a lower preference for the path.
