Which two parameters must you configure in neighbor-range for ADVPN iBGP deployment?

In an ADVPN deployment using iBGP, the Hub uses dynamic BGP peering to manage a large number of spokes. The neighbor-range configuration is used to define the range of IP addresses from which the Hub will accept dynamic BGP connections.

neighbor-group: Within the neighbor-range, you must specify a neighbor-group. This group acts as a template that defines the shared settings for all spokes in that range.

remote-as: The remote-as is a mandatory parameter defined within the associated neighbor-group to identify the autonomous system of the spokes (which, in iBGP, matches the Hub ' s AS). While route-reflector-client is also a required setting for the Hub in this topology, it is a property configured under the neighbor-group, whereas neighbor-group and the group ' s remote-as are the foundational requirements for the range to function.
