The confederation nonstandard command configures standard devices (in RFC 3065) in a confederation to communicate with nonstandard devices.
The undo confederation nonstandard command configures standard devices in a confederation to communicate only with standard devices.
By default, only standard devices in a confederation can communicate with each other.
Usage Scenario
To communicate with nonstandard devices, configure this command on all switches in a confederation.
Precautions
After the confederation ID is configured, running the confederation nonstandard command will disconnect the sessions between a router and its IBGP peers as well as its confederation EBGP peers. Then, new connections are reestablished.
