Update routing table

JuDi_4 — Wed, 04 Mar 2009 07:58:18 GMT

I have HP-UX B.11.31 server and move him to another network (change IP-address and
gateway using sam).
bash-3.2# netstat -rn
Routing tables
Destination Gateway Flags Refs Interface Pmtu
127.0.0.1 127.0.0.1 UH 0 lo0 32808
1.2.3.8 1.2.3.8 UH 0 lan900 32808
1.2.3.0 1.2.3.8 U 2 lan900 1500
127.0.0.0 127.0.0.1 U 0 lo0 32808
default 1.2.3.1 UG 0 lan900 1500
default 1.2.6.1 UG 0 lan900 1500

and i see 2 default gateway.
How can i refresh routing table without reboot?

Thanks...

In 11.31 you could have multiple gateways.

You could either delete the gateway via

# route delete gateway

To flush the routing table

# route -f

for this you need to logged in via console, since this disconnect all the users who are logged.
This doesnt require any reboot

route delete default 1.2.6.1
in any case there is no direct route to 1.2.6.1
so I think that dead gateway detection may mark it as dead
check with ndd -get /dev/ip ip_ire_status
if its status is not DEAD.

Bonjour,

And don't forget to modify /etc/rc.config.d/netconf or at next reboot there is a chance that you see this route back in your routing table : I guess that sam did not work properly with this file ;-)

" # route delete gateway "
i suppose that i will delete both gateways.

" # route -f "
It will delete all routes.

I don't want destroy routing table.
I want refresh routing table.

Hi Judi.

There is no refreshing of routing table.

Please let us know what exactly you like to have

You could delete one specific gateway which you like via route delete
