Cisco and Juniper both support this (overload) in OSPFv2 using the process described in RFC 3137. Juniper use the familiar 'overload' command under the OSPF configuration, Cisco use the 'max-metric router-lsa' [1] command under the OSPF config. Both should give similar results to ISIS overload. ~Matt 1: http://www.cisco.com/en/US/products/ps6599/products_white_paper09186a00800ade18.shtml
