Introduction\n\nThis is the design specification for next hop tracking feature in\nQuagga.\n\n1. Background\n\nRecursive routes are of the form:\n\n p/m --\u003e n\n [Ex: 1.1.0.0/16 --\u003e 2.2.2.2]\n\nwhere \u0027n\u0027 itself is resolved through another route as follows:\n\n p2/m --\u003e h, interface\n [Ex: 2.2.2.0/24 --\u003e 3.3.3.3, eth0]\n\nUsually, BGP routes are recursive in nature and BGP nexthops get\nresolved through an IGP route. IGP usually adds its routes pointing to\nan interface (these are called non-recursive routes).\n\nWhen BGP receives a recursive route from a peer, it needs to validate\nthe nexthop. The path is marked valid or invalid based on the\nreachability status of the nexthop. Nexthop validation is also\nimportant for BGP decision process as the metric to reach the nexthop\nis a parameter to best path selection process.\n\nAs it goes with routing, this is a dynamic process. Route to the\nnexthop can change. The nexthop can become unreachable or\nreachable. In the current BGP implementation, the nexthop validation\nis done periodically in the scanner run. The default scanner run\ninterval is one minute. Every minute, the scanner task walks the\nentire BGP table. It checks the validity of each nexthop with Zebra\n(the routing table manager) through a request and response message\nexchange between BGP and Zebra process. BGP process is blocked for\nthat duration. The mechanism has two major drawbacks:\n\n(1) The scanner task runs to completion. That can potentially starve\n the other tasks for long periods of time, based on the BGP table\n size and number of nexthops.\n\n(2) Convergence around routing changes that affect the nexthops can be\n long (around a minute with the default intervals). The interval\n can be shortened to achieve faster reaction time, but it makes the\n first problem worse, with the scanner task consuming most of the\n CPU resources.\n\n\"Next hop tracking\" feature makes this process event-driven. It\neliminates periodic nexthop validation and introduces an asynchronous\ncommunication path between BGP and Zebra for route change notifications\nthat can then be acted upon.\n\n2. Goal\n\nStating the obvious, the main goal is to remove the two limitations we\ndiscussed in the previous section. The goals, in a constructive tone,\nare the following:\n\n- fairness: the scanner run should not consume an unjustly high amount\n of CPU time. This should give an overall good performance and\n response time to other events (route changes, session events,\n IO/user interface).\n\n- convergence: BGP must react to nexthop changes instantly and provide\n sub-second convergence. This may involve diverting the routes from\n one nexthop to another.\n\n3. Overview of the changes\n\nThe changes are in both BGP and Zebra modules. The short summary is\nthe following:\n\n- Zebra implements a registration mechanism by which clients can\n register for next hop notification. Consequently, it maintains a\n separate table, per (VRF, AF) pair, of next hops and interested\n client-list per next hop.\n\n- When the main routing table changes in Zebra, it evaluates the next\n hop table: for each next hop, it checks if the route table\n modifications have changed its state. If so, it notifies the\n interested clients.\n\n- BGP is one such client. It registers the next hops corresponding to\n all of its received routes/paths. It also threads the paths against\n each nexthop structure.\n\n- When BGP receives a next hop notification from Zebra, it walks the\n corresponding path list. It makes them valid or invalid depending\n on the next hop notification. It then re-computes best path for the\n corresponding destination. This may result in re-announcing those\n destinations to peers.\n\n4. Design\n\n4.1. Modules\n\nThe core design introduces an \"nht\" (next hop tracking) module in BGP\nand \"rnh\" (recursive nexthop) module in Zebra. The \"nht\" module\nprovides the following APIs:\n\nbgp_find_or_add_nexthop() : find or add a nexthop in BGP nexthop table\nbgp_find_nexthop() : find a nexthop in BGP nexthop table\nbgp_parse_nexthop_update() : parse a nexthop update message coming\n from zebra\n\nThe \"rnh\" module provides the following APIs:\n\nzebra_add_rnh() : add a recursive nexthop\nzebra_delete_rnh() : delete a recursive nexthop\nzebra_lookup_rnh() : lookup a recursive nexthop\n\nzebra_add_rnh_client() : register a client for nexthop notifications\n against a recursive nexthop\n\nzebra_remove_rnh_client(): remove the client registration for a\n recursive nexthop\n\nzebra_evaluate_rnh_table(): (re)evaluate the recursive nexthop table\n (most probably because the main routing\n table has changed).\n\nzebra_cleanup_rnh_client(): Cleanup a client from the \"rnh\" module\n data structures (most probably because the\n client is going away).\n\n4.2. Control flow\n\nThe next hop registration control flow is the following:\n\n\u003c\u003d\u003d\u003d\u003d BGP Process \u003d\u003d\u003d\u003d\u003e|\u003c\u003d\u003d\u003d\u003d Zebra Process \u003d\u003d\u003d\u003d\u003e\n |\nreceive module nht module | zserv module rnh module\n----------------------------------------------------------------------\n | | |\nbgp_update_ | | |\n main() | bgp_find_or_add_ | |\n | nexthop() | |\n | | |\n | | zserv_nexthop_ |\n | | register() |\n | | | zebra_add_rnh()\n | | |\n\nThe next hop notification control flow is the following:\n\n\u003c\u003d\u003d\u003d\u003d Zebra Process \u003d\u003d\u003d\u003d\u003e|\u003c\u003d\u003d\u003d\u003d BGP Process \u003d\u003d\u003d\u003d\u003e\n |\nrib module rnh module | zebra module nht module\n----------------------------------------------------------------------\n | | |\nmeta_queue_ | | |\n process() | zebra_evaluate_ | |\n | rnh_table() | |\n | | |\n | | bgp_read_nexthop_ |\n | | update() |\n | | | bgp_parse_\n | | | nexthop_update()\n | | |\n\n4.3. zclient message format\n\nZEBRA_NEXTHOP_REGISTER and ZEBRA_NEXTHOP_UNREGISTER messages are\nencoded in the following way:\n\n/*\n * 0 1 2 3\n * 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1\n * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+\n * | AF | prefix len |\n * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+\n * .
