E
External Border Gateway Protocol (BGP). Operates between external systems.
eBGP
Enhanced Interior Gateway Protocol. A Cisco routing protocol that uses the Diffusing Update
EIGRP
Algorithm to provide fast convergence and minimized bandwidth utilization.
F
The lowest calculated distance to a network destination in EIGRP. The feasibility distance is the sum
feasible distance
of the advertised distance from a neighbor plus the cost of the link to that neighbor.
Neighbors in EIGRP that advertise a shorter distance to the destination than the current feasibility
feasible successor
distance.
Fowarding Information Base. The forwarding table on each module that is used to make the Layer 3
FIB
forwarding decisions per packet.
G
A switch or router that forwards Layer 3 traffic from a LAN to the rest of the network.
gateway
h
H
The configurable time between each Hello packet sent by an OSPF or EIGRP router.
hello interval
A special message used by OSPF or IS-IS to discover neighbors. Also acts as a keep alive messages
hello packet
between established neighbors.
In BGP - Maximum time limit allowed in BGP between UPDATE or KEEPALIVE messages. If this
hold time
time is exceeded, the TCP connection between the BGP peers is closed.
In EIGRP, the maximum time allowed between EIGRP Hello messages. If this time is exceeded, the
neighbor is declared unreachable.
The number of routers that can be traversed in a route. Used by RIP.
hop count
I
Internal Border Gateway Protocol (BGP). Operates within an autonomous system.
iBGP
ICMP
Internet Engineering Task Force Request for Comments.
