Example 2, Public Peering using OpenConfig (JSON over gRPC)

This example script requires the ID of a peering LAN from PeeringDB. It will then query the PeeringDB for all networks on that LAN and build up the OpenConfig BGP configuration to push to a network device to configure a peering sessions with all the peers on that IX peering LAN (it will serialise it to JSON and push over gRPC).

These OpenConf YANG modules need to be compiled using PyangBind for this example:

The script will generate the config for IPv4 and IPv6 sessions only for networks with an open peering policy. The final OpenConfig configuration is printed to the screen in JSON format and pushed to a Cisco IOS-XRv 6.2.1 device using Cisco's gRPC python client, for networks with a restrictive peering policy their details are printed so that they may be contacted. There is a caveat with this script (as its just a PoC) that if a network has two or more peering sessions to an IXP only one session is configured per network. Also note that when run against a very large exchange like the LINX London (Juniper / LON1) exchange, the script will take at least 5 minutes to run:

        Two issues are now present:

        Firstly some of the syntax of the serialised JOSN is not accepted by IOS-XRv.
        Some of the OpenConfig BGP type definitions are using upper-case
        and IOS-XRv only seems to support lower case, for example
        "IPV4_UNICAST" AFI/SAFI must be "ipv4-unicast".

        Also the "restart-timer" is a float value in the OpenConfig type defs so ater
        being serialised from OC object to JSON the int is converted to a float,
        IOS-XRv wants an int so it is re-set below.
