480 Configuring BGP
NOTE
In complex legacy networks, RIP, OSPF, BGP and IS-IS may all be active on the same router at the same
time. Typically, however, only one dynamic routing protocol is employed at one time.

Configuring BGP
To configure dynamic routing with BGP, do the following:
1. Make sure the CLI is in Configuration mode.
2. Navigate to
routing » bgp and configure the following parameter(s) as required:
Parameter Description
enabled Enables BGP.
as-id { as-id } Synopsis: A 32-bit unsigned integer between 1 and 65535
Autonomous System ID.
always-compare-med Always comparing MED from different neighbors.
reachability-check Synopsis: { true, false }
Default: true
Enables or disables the reachability check for advertised routes.
When enabled, before advertising a self-generated BGP route to other BGP peers, the BGP
daemon checks if the advertised route is reachable locally by default before advertising it
to other BGP peers. The route is only advertised if it exists in the kernel routing table.
default-local-preference { default-local-
preference }
Synopsis: A 32-bit unsigned integer
Default: 100
Default local preference value.
deterministic-med Pick the best-MED path among paths advertised from neighboring AS.
