max-metric router-lsa Configure the maximum cost of 65535 on a new router so that it functions as a stub router in the network and OSPF traffic destined to other networks is not forwarded on a path through the router. C-Series, E-Series, Z-Series, S4810 Syntax max-metric router-lsa [on-startup {announce-time | wait-for-bgp [wait-time]}] To remove the maximum metric assignment from an OSPF router and send LSAs with the currently configured cost, enter no max-metric router-lsa [on-startup {announce-time | waitfor-bgp [wait-time]}]. Parameters on-startup announce-time Enter the time (in seconds) following boot-up during which the maximum cost (65535) for transmitting OSPF traffic on router interfaces is announced in LSAs and the router functions as a stub router. Range: 5 to 86400 seconds. on-startup waitfor-bgp [waittime] Enable the router to announce the maximum metric in OSPF LSAs until the BGP routing table converges with updated routes. Default: 600 seconds. You can also specify the time (in seconds) that the router waits for the BGP routing table to converge before it stops advertising the maximum cost in LSAs and advertises the router's currently configured OSPF cost. Range: 5 to 86400 seconds. Defaults Command Modes Command History Usage Information Not Configured. ROUTER OSPF Version 9.1.(0.0) Version 8.4.2.5 Version 8.4.1.3 Introduced on the S4810 and Z9000. Introduced on C-Series and E-Series TeraScale. Introduced on E-Series ExaScale. When you bring a new router onto an OSPF network, you can configure the router to function as a stub router by globally reconfiguring the OSPF link cost so that other routers do not use a path that forwards traffic destined to other networks through the new router for a specified time until the router's switching and routing functions are up and running, and the routing tables in network routers have converged. By using the max-metric router-lsa command, you force the link cost of all OSPF non-stub links to the maximum link cost (65535). The advertisement of this maximum metric causes other routers to assign a cost to the new router that is higher than the cost of using an alternate path. Because of the high cost assigned to paths that pass through the new router, other routers will not use a path through the router as a transit path to forward traffic to other networks. 1062
