route update

[Corinne HEINRICH]

I've got a problem when I disconnect my HP 8000 workstation to the network. After being connected back to the switch, the route is not update and I cannot access back to the network. In the /etc/rc.config.d/netconf file, my main network is correctly defined as address[0] and I've got as well a default address. Other information , I'm not using dynamic routes ( gated in not used ) but static routes.
What need to be configured to able route update after network disconnection and reconnection.

Thanks

See if:
ndd -get /dev/ip ip_ire_gw_probe_interval
comes back with a non-zero value (probably 180000)

When you disconnect the network HPUX can not ping the default gateway so it assumes it is dead. It should start working again in about 3 minutes (or whatever yours has been changed to if not 180000) but odds are you weren't that patient.

"ip_ire_gw_probe_interval:

Controls the probe interval for Dead Gateway Detection.
IP periodically probes active and dead gateways.
ip_ire_gw_probe_interval controls the frequency of probing.
With retries, the maximum time to detect a dead gateway is
ip_ire_gw_probe_interval + 10000 milliseconds. Maximum time
to detect that a dead gateway has come back to life is
ip_ire_gw_probe_interval. [15000,- ]
Default: 180000 (3 minutes)"



ndd -set /dev/ip ip_ire_gw_probe_interval 0

will turn it off so you can test to see if that solves your problem but in order to make it stay after a reboot you have to edit /etc/rc.config.d/nddconf to add:

TRANSPORT_NAME[0]=ip
NDD_NAME[0]=ip_ire_gw_probe_interval
NDD_VALUE[0]=0

(If you already have entries in nddconf then put this at the end of the file and change the [0]'s to whatever the next number is in the sequence.)
