Global Broadcast
Determines whether the router accepts or discards a global broadcast message, a
message with an IP destination address consisting entirely of 1 digits.
Default: Yes
No
Allows the router to discard global broadcast messages, effectively disabling the
Routing Information Protocol (RIP).
Note: Routers use the Routing Information Protocol (RIP) to exchange route
information, maintain routing tables, and determine a path by using a distance-vector
algorithm. Setting Global Broadcast to No effectively disables RIP, which uses the
global broadcast message to propagate periodic routing updates.
Yes
Lets the router accept the global broadcast message.
Header
Determines whether the IP header or the upper level protocol header is selected
when creating a user-defined IP filter.
Default: Network
After Network
Selects the upper level protocol header.
Network
Selects the IP header.
Hello Interval
Specifies the number of seconds between the TCP/IP router’s transmission of OSPF
Hello packets. Hello packets are transmitted across each OSPF interface. On
broadcast interfaces, they are used to elect the designated and backup designated
router, and to discover and maintain neighbor relationships.
Default: 5 (seconds)
Options
10, 15, 20, 30, or 60 seconds
Note: All routers connected to the OSPF backbone must be configured with the same
values for Hello Interval and Dead Interval.
Hello Timer
Specifies the time interval, in seconds, between EGP Hello commands.
Default: 60 (seconds)
Options
30, 40, 50, 60, 70, 80, 90, 100, 110, and 120 (seconds)
High Value (hex)
Sets the upper boundary range of the hexadecimal bit pattern when creating a user-
defined filter.
