Glossary

core gateway

The innermost gateways of the ARPAnet. These gateways have a total picture of the reacha- bility to all networks known to the ARPAnet with EGP. They then redistribute reachabil- ity information to all those gateways speak- ing EGP. It is from them your EGP agent (there is one acting for you somewhere if you can reach the ARPAnet) finds out it can reach all the nets on the ARPAnet. Which is then passed to you via Hello, gated, RIP….

count to infinity

The symptom of a routing problem where routing information is passed in a circular manner through multiple gateways. Each gate- way increments the metric appropriately and passes it on. As the metric is passed around the loop, it increments to ever increasing values til it reaches the maximum for the routing protocol being used, which typically denotes a link outage.

hold down

When a router discovers a path in the network has gone down announcing that that path is down for a minimum amount of time (usually at least two minutes). This allows for the pro- pagation of the routing information across the network and prevents the formation of routing loops.

split horizon

When a router (or group of routers working in consort) accept routing information from mul- tiple external networks, but do not pass on information learned from one external network to any others. This is an attempt to prevent bogus routes to a network from being propagated because of gossip or counting to infinity.
