BGP default-originate issues on N3024 switch
Below is the configuration of the two switches. I have BGP established and up, passing prefixes. I want Switch 1 to send a default gateway to Switch 2 and have the default-originate command setup on the neighbor statement. I do not see the 0.0.0.0 default route in the show ip bgp sum command, but that is detailed in the configuration guide. However, I do not see a default 0.0.0.0 route in the route table for switch 2 at all and receive an error that there is no default route available. What would I be missing here?
Config is below:
SWITCH 1

Solution:
Dell switches require this to be turned on in the config.
router bgp *AS Number*
default-information originate always
