DEFVAL { 1 } ::= { ospfVirtIfEntry 3 } ospfVirtIfRetransInterval OBJECT-TYPE SYNTAX UpToMaxAge MAX-ACCESS read-create STATUS current DESCRIPTION "The number of seconds between link-state ad- vertisement retransmissions, for adjacencies belonging to this interface. This value is also used when retransmitting database descrip- tion and link-state request packets. This value should be well over the expected round- trip time." DEFVAL { 5 } ::= { ospfVirtIfEntry 4 } ospfVirtIfHelloInterval OBJECT-TYPE SYNTAX HelloRange MAX-ACCESS read-create STATUS current DESCRIPTION "The length of time, in seconds, between the Hello packets that the router sends on the in- terface. This value must be the same for the virtual neighbor." DEFVAL { 10 } ::= { ospfVirtIfEntry 5 } ospfVirtIfRtrDeadInterval OBJECT-TYPE SYNTAX PositiveInteger MAX-ACCESS read-create STATUS current DESCRIPTION "The number of seconds that a router's Hello packets have not been seen before it's neigh- bors declare the router down. This should be some multiple of the Hello interval. This value must be the same for the virtual neigh- bor."

Note that unauthenticated interfaces need no authentication key, and simple password authen- tication cannot use a key of more than 8 oc- tets. Larger keys are useful only with authen- tication mechanisms not specified in this docu- ment. When read, ospfVifAuthKey always returns a string of length zero."
