Creating ip alias on bonded interface ie. bond0:1
Solution 1
Does the bonding kernel module loads properly or not ?
If not, it could be related to a dependency issue w/ ipv6, appeared in rhel5.4 with bonding driver 3.4.0.
the following commands should resolve this issue:
# touch /etc/modprobe.d/disable-ipv6
# echo "options ipv6 disable=1" >> /etc/modprobe.d/disable-ipv6
Solution 2
You do not have a GATEWAY line. The only thing that can reach those interfaces are other devices on the same vlan

Bonded interface is working fine for a long time. I just went to add an alias the way I always have on a regular interface, and on first check it works (pinging on the local box) but it is not accessable from outside (iptables is turned off). In addition with this setup the normal network response started to decline, hanging for around a minute before I could get a prompt on login.
Here are my config files:
[root network-scripts]# cat ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no [root network-scripts]# cat ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no [root network-scripts]# cat ifcfg-bond0 DEVICE=bond0 BONDING_OPTS="mode=1 miimon=100" BOOTPROTO=none ONBOOT=yes NETWORK=10.2.1.0 NETMASK=255.255.255.0 IPADDR=10.2.1.11 USERCTL=no [root network-scripts]# cat ifcfg-bond0:1 DEVICE=bond0:1 BOOTPROTO=static ONBOOT=yes NETWORK=10.2.1.0 NETMASK=255.255.255.0 IPADDR=10.2.1.12 USERCTL=no
any thoughts?

Govindarajulu almost 13 yearsRubbish. Adding aliases for eth0 and eth1 will not solve anything. It is perfectly ok to create an alias for bond0 without aliasing its slaves.
