Just as we saw modifying the caching time for ARP entries in the ARP table here. We can modify the default time that a sun Solaris system can hold the routing entries.
The default time for which a dynamically learnt Route entry in the routing table is 20mins (1200000ms)
To Display current Route holding time
To display the current time interval to hold a route entry
In Solaris 8/9/10
sunsolaris# ndd -get /dev/ip ip_ire_arp_interval
1200000
In earlier versions to Solaris 8
sunsolaris# ndd -get /dev/ip ip_ire_flush_interval
To modify the Route holding time
This can be modified or reduced to a lower level. To modify the default time to say 15 mins
In Solaris 8/9/10
sunsolaris# ndd -set /dev/ip ip_ire_arp_interval 900000
In earlier versions to Solaris 8
sunsolaris# ndd -set /dev/ip ip_ire_flush_interval 900000
