9. BGP uses the route with the lowest IGP metric to the BGP nexthop.
10. BGP prefers EBGP over IBGP. All confederation paths are considered IBGP.
11. If the best route and a new route are both external and maximum-paths n is
enabled, BGP inserts the new route into the IP routing table as an alternate path.
EBGP multipath load sharing can occur at this point. The forwarding table holds
1 - 2 paths.
12. BGP prefers the path with the lowest IP address specified by the BGP router ID.
Configuring the Local Preference
When multiple paths exist to the same destination, the local preference specifies the
preferred path. The preferred path is the one with the higher preference value. To
configure the local preference of a BGP path, perform one of the following steps.
1. To set the default local preference attribute in BGP updates, use the bgp default
local-preference command in Router BGP Configuration mode, as shown below:
MOT(config-bgp)#bgp default local-preference <preference-value>
where:
preference-value – the local preference number in the range 0 – 4294967295
2. Use a route map to set the local preference attribute
Example: Setting the Local Preference
This example configures Routers New York and Boston so that AS 100 receives
updates for network 156.10.0.0 from AS 200 and AS 400 (as shown in Figure 12-17).
