Protocol Configuration¶
As a first step, a new protocol instance needs to be configured. It is a very basic configuration conforming with RFC4271.
Note
RIB policy must already be configured and present before configuring the protocol.

@line 2: The unique protocol instance identifier.
@line 7: BGP Identifier of the speaker.
@line 8: Local autonomous system number of the speaker. Note that, OpenDaylight BGP implementation supports four-octet AS numbers only.

The new instance presence can be verified via REST:

@line 3: Loc-RIB - Per-protocol instance RIB, which contains the routes that have been selected by local BGP speaker’s decision process.
@line 4: The BGP-4 supports carrying IPv4 prefixes, such routes are stored in ipv4-address-family/unicast-subsequent-address-family table.
