Configuring IP Exterior Gateway Protocols (BGP and EGP)
5-2
308628-15.0 Rev 00
When a BGP speaker receives a route in an update message, it applies any local
routing policies to determine whether the router will use the route and whether it
will advertise the route to other routers. Then, if the route can be used, it is
compared against routes from other protocols and possibly included in the
forwarding table.
This chapter covers the following topics:
Configuring a BGP Accept Policy
BGP accept policies determine which routes BGP submits to the IP routing table
manager.
To configure a new BGP accept policy, you must do the following:
• Supply a name for the accept policy.
• Specify whether BGP ignores or accepts an update that matches the policy.
• Rank the policy according to preference, precedence, and BGP weight class.
You can use the BCC or Site Manager to define BGP accept policies. You can
configure up to 32 BGP accept policies.
