ECMP Question?

[8053zz]

In my config I have 2 default routes. By having 2 default routes does this automatically enable ECMP? If so, is there a command or script I can run to see some type of flow table information?

This is on a CSS 11503.

Thanks.

ECMP is on by default.

So when you have 2 routes identical it should take effect when necessary.

To see flows, you can do a 'show flows x.x.x.x'

or from llama mode a 'flow-agent show active'.

Thanks for the info. Follow up: If I was sending, say MAPI, traffic through the CSS (not loadbalanced) would using 2 default routes become an issue since the traffic needs to be routed back to the original firewall (1 of the default routes - not in a firewall loadbalancing senario)? or is the CSS making a decision prior based on some type of table information even though a VIP does not reside on the box.

Thanks

it should be ok normally.

That's the purpose of ECMP.
