Hi, The default gateway (172.17.220.1) cannot be pinged via the default interface bond0 (172.17.220.231), but can be pinged via interface eth1 (10.201.135.73).
Ping is supposed to work with the default interface bond0. Because the virtual interface bond0 can be pinged by systems in the same subnet, bond0 is working (right?). There must be a routing issue. Here is the interfaces info:
OS is RHEL 4.9 (Linux). Please help. Thank you much in advance!

(1) It can ping itself by IP on both interfaces.
(2) Other hosts in the same subnet can ping bond0, but not eth1.
Thanks.

Can other hosts on either net ping it on both IP?

As you haven't shown any other interface configurations you should have this entry in one of them (i.e. /etc/sysconfig/network-scripts/ifcfg-eth0)

So, the 10. interface that can route is not pingable, and the 172. interface that cannot arp its gateway is pingable? Maybe we should get some traceroute's or something. The 10. might not ping because of routing setup, as 10. is only routable within an intranet. If the 172. pings from outside, it can obviously find a route, and we wonder what that is! Some tcpdump or whatever can tell us how far it gets on the lan. What does the arp cache look like for the 172. hosts? (ARP cache generally has a life of minutes.)
