The available traffic capacity of a link.
bandwidth
Backup designated router. An elected router in a multi-access OSPF network that acts as the backup if
BDR
the designated router fails. All neighbors form adjacencies with the backup designated router (BDR)
as well as the designated router.
Border Gateway Protocol. BGP is an interdomain or exterior gateway protocol.
BGP
A remote BGP speaker that is an established neighbor of the local BGP speaker.
BGP peer
BGP-enabled router.
BGP speaker
C
Measure of the operating cost to route over a link.
communication cost
The point at which all routers in a network have identical routing information.
converged
See converged.
convergence
D
The time within which an OSPF router must receive a Hello packet from an OSPF neighbor. The dead
dead interval
interval is usually a multiple of the hello interval. If no Hello packet is received, the neighbor adjacency
is removed.
A router to which all unroutable packets are sent. Also called the router of last resort.
default gateway
The length of time required to move a packet from the source to the destination through the
delay
internetwork.
See DR.
designated router
Dynamic Host Control Protocol.
DHCP
See DUAL.
Diffusing Update
Algorithm
Defines routes by distance (for example, the number of hops to the destination) and direction (for
distance vector
example, the next-hop router) and then broadcasts to the directly connected neighbor routers.
Domain Name System client. Communicates with DNS server to translate a host name to an IP address.
DNS client
Designated router. An elected router in a multi-access OSPF network that sends LSAs on behalf of all
DR
its adjacent neighbors. All neighbors establish adjacency with only the designated router and the
backup designated router.
Diffusing Update Algorithm. EIGRP algorithm used to select optimal routes to a destination.
