Routing on Appliance 5230

Question

Hi&nbsp;

We are trying to add a route to our existing appliance 5230, running at 2.6.0.3. This is configured in media server role.

Currently this server is getting used for backup of only one client which contains Netezza DB.

Now we want to use this appliance also for backup of few more clients and those clients are not reachable from this appliance.

I checked there are no routes for those clients on this appliance.

following is current routing table:

Destination &nbsp; &nbsp; Gateway &nbsp; &nbsp; &nbsp; &nbsp; Genmask &nbsp; &nbsp; &nbsp; &nbsp; Flags &nbsp; MSS Window &nbsp;irtt Iface
	10.100.249.0 &nbsp; &nbsp;0.0.0.0 &nbsp; &nbsp; &nbsp; &nbsp; 255.255.255.240 U &nbsp; &nbsp; &nbsp; &nbsp; 0 0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0 bond1
	10.100.14.0 &nbsp; &nbsp; 10.100.14.254 &nbsp; 255.255.255.0 &nbsp; UG &nbsp; &nbsp; &nbsp; &nbsp;0 0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0 bond0
	192.168.229.0 &nbsp; 0.0.0.0 &nbsp; &nbsp; &nbsp; &nbsp; 255.255.255.0 &nbsp; U &nbsp; &nbsp; &nbsp; &nbsp; 0 0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0 eth0
	10.100.7.0 &nbsp; &nbsp; &nbsp;10.100.14.30 &nbsp; &nbsp;255.255.255.0 &nbsp; UG &nbsp; &nbsp; &nbsp; &nbsp;0 0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0 bond0
	10.100.117.0 &nbsp; &nbsp;10.100.14.30 &nbsp; &nbsp;255.255.255.0 &nbsp; UG &nbsp; &nbsp; &nbsp; &nbsp;0 0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0 bond0
	169.254.0.0 &nbsp; &nbsp; 0.0.0.0 &nbsp; &nbsp; &nbsp; &nbsp; 255.255.0.0 &nbsp; &nbsp; U &nbsp; &nbsp; &nbsp; &nbsp; 0 0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0 eth0
	127.0.0.0 &nbsp; &nbsp; &nbsp; 0.0.0.0 &nbsp; &nbsp; &nbsp; &nbsp; 255.0.0.0 &nbsp; &nbsp; &nbsp; U &nbsp; &nbsp; &nbsp; &nbsp; 0 0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0 lo

bond0 has IP - 10.100.14.30&nbsp;

bond1 has IP&nbsp;- 10.100.249.5

eth0 has default IP.

I am able to ping gateway 10.100.14.254 from the destination clients. Now when i try to add static route from WEB GUI, it refelcts error "Default gateway is in use".

when I try to add route from CLISH, i recieve following error message.

Gateway Add 10.100.14.254 10.100.28.0 255.255.255.0 bond0
	name:########01:

	- [Error] Failed to add new network route entry

Please assist.

Hi sdo&nbsp;

&nbsp;

Thanks, issue has been fixed.

All i need to delete all gateway and network cofnfig and readd them again.

Not enough information.

To make any sense of this we need to see:

IP address, interface,&nbsp;subnet, network, netmask, CIDR, gateway&nbsp;... all seven of these items... for all three of these... &nbsp; master bond0, master bond1, one of the new clients... i.e. we need 21 pieces of information.

Thanks sdo.

Can you explain what is CIDR ?

I checked with Netwrok people they are able to ping these gateways from each other, now i can assume &nbsp;reason behind this issue could be " there is no default route on appliance".

something like 0.0.0.0 &nbsp; &nbsp;10.100.14.254&nbsp; &nbsp; &nbsp;0.0.0.0 &nbsp; &nbsp; U &nbsp; &nbsp; &nbsp; &nbsp; 0 0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0 bond0

but when I tried to add this static route, I again recieved an error " Default Gateway is already in use".

CIDR:

https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

...think of it as a shorthand way of expressing the network and netmask together... but usually network engineers like to see the details of any network issues&nbsp;expressed in all forms both shorthand and longhand - hence things are much easier to diagnose when all of "interface, IP, network, subnet, netmask, CIDR, gateway" are specified in discussions.
