Appendix K Router Platform User Interface Reference

OSPF Interface Policy Page

Table K-110	OSPF Interface Dialog Box (Continued)
Priority		The default priority of the interface. The priority is used to determine which
		routers become the designated router (DR) and backup designated router
		(BDR) for that segment. The higher the number, the higher the priority.
		The default priority is 1. Valid values range from 0 to 255.
		Note To exclude the interface from election as DR or BDR, assign a
		priority of 0. Configure router priority only for interfaces to
		multiaccess networks, not point-to-point networks.
MTU Ignore		When selected, ignores MTU mismatches between neighboring routers.
		When deselected, MTU mismatch detection is enabled.
		Note Typically, this option is not used, because it can cause routers to
		become stuck in exstart/exchange state, which prevents OSPF
		adjacency from being established.
Database Filter		When selected, blocks link-state advertisement (LSA) flooding to the
		selected interface.
		When deselected, LSA flooding is permitted.
		Note We recommend that you enable this option on fully-meshed
		networks. This option is not available for point-to-multipoint
		networks.
Hello Interval		The default interval (in seconds) between hello packets sent over the selected
		interface. These packets are used by neighboring routers to confirm the
		router sending the packets is still operating. Valid values range 1 to 65535
		seconds.
		Note The hello interval must be the same for all routers and access servers
		in the network.
Transmit Delay		The amount of time OSPF waits (in seconds) before flooding an LSA over
		the link.
		The default is 1 second. Valid values range from 1 to 65535 seconds.
		Note When you configure slow links or on-demand links that queue traffic
		before sending it in bursts, we recommend that you take these link
		delays into account when defining this value.
