Hi,

1) Is there a real need for you to run gated? Does it work when you disable gated?

2) Are you able to ping the default gateway/router? What is the value of ip_ire_gw_probe_interval?

# ndd -get /dev/ip ip_ire_gw_probe_interval

Hope this helps. Regards.

1. I run gated because i have to change route information with my router rip 2 .
If i disable gated,some routes could not be found in HP .
2. I can ping default gateway.
The value of ip_ire_gw_probe_interval is 180000.

How can i do to resolve this problem?
Thank your help.

Hi,

Can you show us your gated.conf? Have you checked your gated logs?

Perform a tcpdump on your outbound interface. Check that your RIP traffic is healthy. By any chance are you running a firewall on this gateway?

I used to run OSPF and IRDP discovery server (aka. RDPD server) on a firewall gateway on Solaris. There was no need to hardcode the default route. The OSPF protocol automatically identifies the correct default gateway/route to use in the routing table based on the advertisements.

Hope this helps. Regards.
