6.7 Routing Protocols

A routing protocol is a protocol that specifies how routers communicate with each other, disseminating information that
enables them to select routes between any two nodes on a computer network. Routing algorithms choose the route. Each
router has a prior knowledge only of networks attached to it directly. A routing protocol shares this information first among
immediate neighbors, and then throughout the network. This way, routers gain knowledge of the topology of the network.
NOTE: These routing protocols require hardware version 2.0.
Choose from the following tabs to configure routing protocols:
• BGP Routing Protocol
• OSPF Routing Protocol
• RIP Routing Protocol
• Route Maps and Filters
6.7.1 BGP Routing Protocol
The latest version of BGP (Border Gateway Protocol) is version 4. BGP-4
is one of the Exterior Gateway Protocols and de facto standard of Inter
Domain routing protocol. BGP-4 is described in RFC1771, A Border
Gateway Protocol 4 (BGP-4). BGP is a distance vector routing protocol,
and the AS-Path framework provides distance vector metric and loop
detection to BGP. RFC1930.
BGP Editor
• Name: Unique name of the policy.
• ASN: The AS (Autonomous System) number is one of the
essential elements of BGP.
• Router-ID: This sets the router-ID of the BGP process. The router-
ID may be an IP address of the router, but need not be - it can be
any arbitrary 32bit number. However it MUST be unique within the
