DR
OSPF interface state that indicates the router itself is the designated router on the network
to which the router is attached.
DR Other
OSPF interface state that indicates that the interface's router is neither the designated
router nor the backup designated router. The interface's router forms adjacencies to both
the designated router and the backup designated router (if applicable).
Exterior Gateway Protocol (EGP)
Internet protocol used to exchange of routing information between autonomous systems.
Flow
Template for specifying the characteristics of network traffic.
Front Panel View
Graphical representation of an SSR's front-panel chassis. For an example Front Panel view,
see
“Front Panel View” on page 30 .
Generation Identifier
Instance identifier assigned to DVMRP whenever that protocol is started on a router.
Hello Packets
Packets sent to acquire neighbors, which are routers on the same network as the router
sending the packet.
Hop Count
Routing metric that measures the distance between a source and destination. A hop is the
moving of packets through a router interface. Data transmitted directly from one router to
another router counts as one hop. Suppose data is being transmitted between router A
and router D. If the data must go through routers B and C before it gets to router D, the
hop count for the route is three.
Protocols that base routing on the hop count will use the route with the least amount of
hops.
Hypertext Markup Language (HTML)
Language that describes the structure of a Web document's contents and defines some of
that document's behavior. HTML permits a file to be linked to other resources, such as text
files, graphic files, sound files, and so on.
Interior Gateway Protocol (IGP)
Internet protocol that supports the exchange of routing information within an
autonomous system.
