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).
Code:
# ping -I eth1 172.17.220.1
PING 172.17.220.1 (172.17.220.1) from 10.201.135.73 eth1: 56(84) bytes of data.
64 bytes from 172.17.220.1: icmp_seq=0 ttl=255 time=5.48 ms
64 bytes from 172.17.220.1: icmp_seq=1 ttl=255 time=0.523 ms
# ping -I bond0 172.17.220.1
PING 172.17.220.1 (172.17.220.1) from 172.17.220.231 bond0: 56(84) bytes of data.
From 172.17.220.231 icmp_seq=1 Destination Host Unreachable
From 172.17.220.231 icmp_seq=2 Destination Host Unreachable
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:
the interface needs to be configured. Is the bond up and running?
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)
Code:
MASTER=bond0
SLAVE=yes

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.)
