1. A method for wireless communication at a first relay, comprising:establishing a first connection to a first data network (DN) via a wireless link with a network node;
receiving, from a second relay, a packet data unit (PDU) session request;
forwarding the PDU session request to a network management function;
identifying, based at least in part on the PDU session request, a DN address for the second relay via a wireless link with a second network node, wherein identifying the DN address further comprises receiving, from the network management function, a DN address prefix, determining the DN address for the second relay based at least in part on the DN address prefix, and transmitting the DN address to the second relay;
establishing a second connection to a second DN for the second relay; and
connecting the second relay to the first DN by routing data from the first DN to the second relay via the second DN based at least in part on the identified DN address.
