Routing Protocols

Multiple routing protocols are available, including ISIS and BGP. To perform comprehensive end-to-end testing for both BNG and non-BNG routers, you can use the BNG Blaster.

The routing protocols are designed to create a virtual node linked to one or multiple network interface functions. These virtual nodes enable the attachment of emulated network topologies. These topologies are generated offline using built-in tools such as lspgen (for ISIS and OSPF), bgpupdate, ldpupdate, or through the creation of custom tools using provided examples.

For ISIS and OSPF, the generated topologies are serialized into an MRT file as defined in RFC6396. This serialized topology can be dynamically updated to simulate link flapping in real-time.

Additionally, commands are available to for example inject LSA/LSP messages via CLI/REST API.

In the case of LDP and BGP, update messages are produced as raw updates and then transmitted to the established session. Similar to ISIS and OSPF, live updates can replace the file to mimic link flapping.
