As per industry trends, Access Networks have been migrating from traditional ATM based networks to Ethernet networks. In Ethernet based access networks, Access Concentrators are typically configured to act as a transparent bridge in Layer 2 mode. These Access Concentrators also act as Layer 2 relay agents. Layer 2 Relay Agent functionality does not provide means to avoid flooding of DHCP messages and also needs to be extended to support DHCP LeaseQuery This draft discusses these issues and provides solutions for the same.
