Restarting the BGP Stub Routing Process
To clear the BGP session established with the neighbor, clear the statistical counters associated with the
session, and restart the BGP with the neighbor, enter the following command:
hostname(config)# clear ip bgp neighbor-addr

OSPF Overview
OSPF uses a link-state algorithm to build and calculate the shortest path to all known destinations. Each
router in an OSPF area contains an identical link-state database, which is a list of each of the router
usable interfaces and reachable neighbors.
The advantages of OSPF over RIP include the following:
•
•
The disadvantage of shortest path first algorithms is that they require a lot of CPU cycles and memory.

OSPF link-state database updates are sent less frequently than RIP updates, and the link-state
database is updated instantly rather than gradually as stale information is timed out.
Routing decisions are based on cost, which is an indication of the overhead required to send packets
across a certain interface. FWSM calculates the cost of an interface based on link bandwidth rather
than the number of hops to the destination. The cost can be configured to specify preferred paths.
